After submitting a question in Qlik Answers, the real-time reasoning output is not displayed while the question is being processed. The reasoning stepper, which normally shows the model’s step-by-step thinking in real time, is either missing or fails to load. The issue may occur intermittently and does not consistently reproduce across sessions or browsers.
Example:
This is a client-side issue, rather than a defect in Qlik Answers, and is commonly caused by a browser extension.
Qlik Answers delivers its real-time reasoning output via a streaming HTTP response (Server-Sent Events / chunked transfer encoding). Browser extensions can interfere with this mechanism by intercepting, buffering, or suppressing streaming network traffic at the browser level. When any such extension disrupts the stream, the reasoning stepper never receives the data it needs to render.
Extension types known to cause this class of conflict include, but are not limited to:
This article documents a solution for Google Chrome.
If the issue persists after disabling all extensions:
The same class of interference can also be caused by corporate network proxies, SSL inspection appliances, or endpoint security agents operating outside the browser. If Incognito also fails to display the reasoning view, engage your IT or network security team to verify whether outbound Server-Sent Event connections to Qlik Cloud are being intercepted or buffered at the network level.
This conflict is not unique to Qlik Answers. Any web application that relies on Server-Sent Events or streaming HTTP responses may be affected by extensions or network components that proxy or intercept traffic at the browser level.
If you continue to experience issues after following the steps above, please open a support case and include the following:
When attempting to add an app to Qlik Answers, the error invalid logical model or other indexing errors appear, followed by the process hanging without further processing or simply erroring out.
The behavior is the same in both user-based tenants and capacity-based tenants.
The app reloads normally when scheduled or when reloaded manually. This indicates there is no issue with the app itself, which is not exhibiting any errors performing typical analytics activity.
If your app has existing business logic, your custom business logic may interfere with the expected Qlik Answers indexing preparation.
To resolve this:
If changes are made to the logical model after performing the above steps, those changes will be reindexed automatically. Keep in mind that this re-indexing may take up to 24 hours.
In some instances, business logic may need to be reset or may not be consistent with best practices, preventing Qlik Answers from indexing the Qlik app.
See Best practices for preparing applications for Qlik Answers for details.

Modern large language models that power advanced AI capabilities, such as Qlik Answers, require processing infrastructure that may not be available in every Qlik region. To provide our AI capabilities in as many regions as possible, Qlik Cloud now offers cross-region inference as an opt-in feature. You determine if available inference locations meet your data residency and compliance requirements.
Latest Update
March 9th, 2026
To deliver the best possible AI capabilities to our customers in Brazil, we are upgrading to modern AI models that require data processing across AWS commercial regions globally.
Starting 9th of April, data processing for Pipelines, API Designer, and Data Governance will move from Brazil-only to all AWS commercial regions.
For complete details about inference locations for your region and data protection measures, see the full documentation available in Enabling cross-region inference.
Please subscribe to this article to receive updates to any inference location.
This article provides answers to the most frequent questions asked about Qlik Answers.
For the Qlik MCP FAQ, see Qlik Model Context Protocol (MCP) FAQ.
In February 2026, we launched our new agentic experience, which will enhance decision-making and improve productivity through a combination of assistants and agents running on a cutting-edge architecture. This initial release includes out-of-the-box agents for structured data analytics, unstructured knowledge, discovery of anomalies, and help and assistance. These agents take advantage of our foundational capabilities, including our data products and unique analytics engine, to execute complex, multi-step tasks in a trusted, scalable, and secure manner.
Qlik Answers is the primary AI assistant for people to interface with agentic AI. It will understand the intent of natural language questions and engage the underlying agentic framework to execute tasks, build responses, and take actions.
Qlik Answers now combines structured data analytics with unstructured content and general knowledge and reasoning from LLMs to deliver the most complete and relevant answers and insights, helping our customers improve decisions, productivity, and business outcomes in ways not possible before.
Looking ahead, as we build additional agents, such as prediction agents and pipeline agents, they will all be invoked through Qlik Answers. A broader set of agents is planned, all aimed at helping users get more value from their data and become more productive as Qlik continues to evolve.
With Qlik Answers now able to handle both structured and unstructured data, you can drive hundreds more informed decisions and actions each day. You can drive productivity through automation of a broad range of data and analytics tasks and workflows. And with plug-and-play simplicity, you can quickly deploy assistants in a matter of hours, reducing risk, speeding time-to-value, and future-proofing their investments in AI.
For now, Qlik Answers will continue to be priced based on current models for the number of questions asked. You get capacity at corresponding levels in Standard, Premium, and Enterprise editions, as well as Qlik Sense Enterprise SaaS, with additional capacity available for purchase as needed.
There is currently no additional cost for structured data questions or task automation requests; a question is a question.
For additional details, refer to Pricing.
Since launch, Qlik Answers has been rolled out across regions, and the process is still ongoing. If you have Standard, Premium, and Enterprise editions, check if your region already supports it (see Supported regions).
If it is not yet available to you, then:
Yes, you must be a Qlik Cloud customer to use Qlik Answers. Qlik Answers is built on cloud-native technologies, specifically large language models (LLMs) that require significant compute resources and specialized infrastructure, and there is no mechanism to deploy these technologies in an on-premises environment.
However, you don’t have to fully migrate their analytics environment or documents to the cloud to take advantage of Qlik Answers. Analytics apps can be pushed to the cloud as needed to support Qlik Answers. See Qlik Answers and applications distributed from Qlik Sense Enterprise on Windows for details.
No. You will use either Qlik Answers or Insight Advisor, not both at the same time.
Qlik Answers represents the AI-first experience going forward. When a tenant chooses Qlik Answers, that becomes the primary way users interact with analytics. Insight Advisor is not available in parallel within the same tenant.
This is a deliberate choice to avoid duplicated experiences, inconsistent results, and user confusion.
No. Qlik Answers is cloud only.
There are no plans to bring Qlik Answers to on-premises environments. The product relies on cloud native AI services, managed infrastructure, and continuous model evolution.
Insight Advisor is not being discontinued.
If you remain on Insight Advisor, you can continue using it. However, within a tenant, you must choose between Insight Advisor and Qlik Answers. You cannot run both experiences side by side.
The most important and relevant business logic is preserved when moving to Qlik Answers.
That said, Qlik Answers is built for a newer generation of AI-driven analytics. In many cases, customers will find they no longer need to manually build or maintain the same level of logic, because the system handles more of that automatically.
The value is not in recreating everything exactly as it was, but in moving to a simpler, more capable experience.
This is essentially a buy vs build decision:
Qlik Answers is built on AWS Bedrock and currently utilizes Anthropic Claude models. The specific model versions vary by agent function and are continuously evaluated and updated based on performance, accuracy, latency, and cost optimization.
Our Model Selection Philosophy:
Qlik maintains flexibility in model selection to continuously improve the user experience as AI technology evolves. Different agents within the Qlik Answers architecture may use different models optimized for their specific tasks (e.g., semantic understanding, code generation, reasoning).
No. Not at this stage.
Qlik Answers is a managed experience with curated models and configurations. Customers who want to use their own models or bring custom AI stacks should use MCP instead.
Yes. Qlik Answers works on top of existing Qlik Sense applications and uses the same data, logic, and security model.
But to get the best experience, apps should be prepared beforehand:
Yes. Master measures and dimensions are always prioritized. If business logic exists, Qlik Answers uses it rather than creating new calculations.
Yes. Qlik Answers generates appropriate visualizations such as KPIs, bar charts, or time-based charts depending on the question.
Qlik Answers inherits and enforces Qlik's established security model without exception. All existing security rules, section access configurations, and row-level security policies apply automatically.
Key security principles:
Field-level security (if implemented) is respected in all analyses.
No additional security configuration is required. Organizations with complex security requirements can continue using their existing Qlik security implementations with confidence.
Yes, if their access rights differ. Answers are always scoped to the user’s permissions.
While no special data preparation is required beyond standard Qlik Sense data modelling best practices, the apps themselves should be prepared beforehand to give you the best experience possible:
Yes. Qlik Answers understands conversational context, allowing users to refine or continue their analysis.
At its initial GA release, Qlik Answers is optimized and fully supported for English language queries and responses.
While the underlying large language models have multilingual capabilities and may be able to process queries in other languages with varying degrees of accuracy, non-English language support is not officially validated, documented, or supported by Qlik at this time.
Additional language support is planned for future releases based on demand and regional priorities.
No. It accelerates analysis and reduces repetitive work but does not replace human expertise or decision-making.
Yes. Only enabled and indexed applications are available.
Not in the current GA release. Qlik Answers operates within the context of a single Qlik Sense application per query. Multi-application query capabilities are planned for a future release.
If you want to ask questions in an app, you just need the ‘Data analysis’ scope. If you plan on asking questions to an assistant, you need the ‘Data analysis’ and ‘Search knowledge base’ scopes.
Cross-region inference has minimal risks as the data still stays within the AWS Virtual Private Network. The only difference here is that the LLM call gets processed in a different region due to GPU availability.
We have made a deliberate design decision to prioritize the quality of answers and insights over the speed of responses. In general, Qlik provides a far richer reasoning process and answer than competing products, and this results in a longer response time. We are planning to improve and optimize this, as well as introduce a faster mode for simpler questions in the future.
Qlik Answers always references its sources in detail. To begin troubleshooting, check the citations, which will show:

For now, Qlik MCP will continue to be priced based on current models for the number of questions asked. You get capacity at corresponding levels in Standard, Premium, and Enterprise editions, as well as Qlik Sense Enterprise SaaS. There is currently no additional cost for structured data questions or task automation requests; a question is a question.
Use of the MCP server consumes questions when Qlik is accessed using Tool Calls. A Tool Call is a request made by the LLM to interact with Qlik's capabilities, such as, but not limited to, querying databases, calling APIs, or performing computations. These are typically visible in the LLM's log.
For Qlik's MCP server, 5 Tool calls consume 1 question. More questions may be purchased for expanded use cases.
See Pricing and the Qlik MCP server product description for details.
Qlik’s pricing does not include your chosen LLM subscription or usage, which will need to be paid separately.
Yes. Qlik MCP works on top of existing Qlik Sense applications and uses the same data, logic, and security model.

When asking the Qlik Answers Documentation Assistant a question and checking the source, it throws the following error:
Cannot access the source
This issue occurs when the Assistant user accessing the Documentation assistant does not have permission to the source. For reference, when setting up a documentation assistant, there should be two spaces:
As the Knowledge base lives in the Assistant Data space, confirm that Can consume data and Can view permissions are set:
For more information, see Qlik Answers use case: Documentation assistant.
In addition, if the Documentation assistant is consuming data from a Direct Access Gateway, confirm that the Assistant users have the permission Can Consume Data for the space where the Direct Access Gateway is installed.
This article answers the most frequently asked questions about Qlik Discovery Agent. It is split into five sub-sections:
If you are looking for information on how to get started, check out the Discovery Agent Interactive Walkthrough and our Discovery Agent Documentation.
Discovery Agent is an AI-powered, always-on monitoring capability in Qlik Cloud that automatically detects meaningful changes, anomalies, and trends in your data. It requires no rules, thresholds, or manual setup. Discovery Agent identifies spikes, drops, trend shifts, baseline changes, and data quality issues, then delivers clear, plain-language insights in a prioritized feed.
Traditional BI alerts rely on predefined thresholds or manual logic. Discovery Agent uses the Qlik Analytics Engine and its associative capabilities to evaluate wide combinations of data relationships automatically and proactively surface only those insights that matter. It is context aware, adaptive, and far more scalable than rules driven systems.
Yes. Discovery Agent is built directly into Qlik Cloud Analytics and leverages the Qlik Analytics Engine for associative, large scale anomaly detection.
Yes. You can ask questions directly from an insight card, and context from the insight will be transferred into Qlik Answers.
No. Discovery Agent is built exclusively for Qlik Cloud.
No. Monitoring runs outside active dashboards, ensuring no performance impact on live analytics experiences.
Yes. Insight delivery respects user permissions, governed access, and security boundaries.
Discovery Agent analyzes updated app data models using associative evaluation to identify:
No rules or thresholds are required.
Discovery Agent is always on, but processes changes when the application’s data model updates. Insights refresh after reload and appear in the feed once the system evaluates new data. Updated are currently capped at one reload per day.
The feed automatically refreshes upon reload. For most apps, this occurs once per day or whenever new data is introduced.
Yes. You can follow specific apps or insight categories once the Following tab is released. Filtering options are also planned to help tailor results.
Insight Triggers are structured metric definitions that serve as the foundation for generating analytical insights within the application. Each trigger is composed of a measure or expression, such as a calculated field or KPI, along with a set of additional configuration parameters. These parameters include the frequency at which the trigger evaluates data and the type of calculation to be applied (example: sum, average, count).
Together, these elements define the conditions under which an insight is surfaced to the user.
Yes, a date period is required for every trigger you configure.
All insights generated by the system are trend-based, meaning they analyze data over time to identify patterns, changes, or anomalies. This requires a date period to be added to the trigger's associated group. Without a defined time range, the system cannot perform the temporal comparisons necessary to produce meaningful insights.
The Insight Feed refreshes automatically each time the page is reloaded. No manual refresh action is required. The feed itself is regenerated once per day, and this regeneration is triggered by the introduction of new data into the application or applications that contain active triggers. As a result, the feed will always reflect the most recent data available as of the last daily reload cycle.
Filtering functionality is available in the Feed. A Filter button is currently visible at the top of the feed during the preview phase of the application. Users can use this to find specific insights in the feed.
Triggers are stored directly within the application in which they are created. They are not stored externally or in a centralized repository. That means each application manages its own set of triggers independently, and triggers defined in one application will not carry over to or affect another application.
Direct question-and-answer functionality within the feed is available.
The Insight Feed is integrated with Qlik Answers, enabling users to ask natural language questions without leaving the feed interface. Because each card displayed in the feed is tied to a specific application, context from the relevant card will be automatically transferred to Qlik Answers to ensure accurate, contextually appropriate responses.
This behavior is expected and occurs specifically after the first reload following the creation of new triggers.
During this initial reload, the system performs a comprehensive scan of all available historical data, rather than only the most recent data. This allows it to identify any and all qualifying insights across the full dataset. This is a one-time process. All subsequent reloads after this initial one will only evaluate and surface insights based on newly introduced data, so the volume of older insights will not continue to grow with each reload.
Yes. The Insight Feed and its associated trigger functionality require the cross-region inference toggle to be enabled. Please ensure this setting is activated in your environment before attempting to configure triggers or access the feed. If you are unsure how to enable the cross-region inference toggle, contact your system administrator or refer to the relevant configuration documentation.
To remove specific insights from the Insight Feed, you must delete the trigger that is generating those insights. Because the feed is dynamically generated based on active triggers, removing a trigger will prevent its associated insights from appearing in future feed reloads.
Deleting a trigger is a permanent action.
If you wish to stop surfacing certain insights temporarily, consider whether disabling or modifying the trigger may be a more appropriate course of action, depending on your platform's available options.
Section Access is not currently supported for applications used with the Insight Feed.
Any application that has Section Access enabled is incompatible with this feature at this time. As a result, all users who have been granted access to a given application will be able to see the insights generated from that application's triggers, regardless of any Section Access restrictions that may otherwise apply within that application.
This is an important consideration when deciding which applications to configure with triggers, particularly for datasets that contain sensitive or role-restricted data. Support for Section Access may be introduced in a future release.
Below is the minimum data requirement:
Weekly/Monthly/Quarterly/Yearly aggregation
Daily aggregation
Missing dates in the date field may prevent calculations. Creating a master calendar in the
load script can resolve this. Qlik is exploring options for date imputation.
OpenAI/ChatGPT now sends a request redirect_uri during the OAuth authorization flow (visible as a new “Redirect” field in ChatGPT’s UI). Qlik Cloud validates that redirect_uri against the Redirect URLs registered on the associated OAuth client. If the exact URL isn’t registered, Qlik rejects the login with errors like Invalid redirect_uri, redirect_uri is not registered, code OAUTH-1 (HTTP 400). This is standard OAuth behavior and is enforced by Qlik’s OAuth endpoints.
Qlik’s MCP administration guide explicitly instructs tenant admins to add the LLM client’s callback URL under Add redirect URLs, and it gives explicit examples (including ChatGPT):
https://chatgpt.com/connector_platform_oauth_redirecthttps://claude.ai/api/mcp/auth_callback
There are several possibilities why this may have worked previously in your setup:
Insight Advisor is not available when a tenant is using the Qlik Answers agentic experience. Use Qlik Answers instead to explore your application's data and create sheets and charts. For more information, see Qlik Answers.
You may wish to switch back to Insight Advisor if your deployment relies on the Microsoft Teams integration.
Disable Qlik Answers.
See Control access to AI features.
This article provides a practical guide for data modelers, BI admins, and analytics engineers.
Qlik Answers is a powerful solution - it lets your business users ask questions in plain language and get accurate, contextual answers directly from your data model. No dashboard navigation, no waiting on report requests. Just ask, and get an answer.
Out of the box, Qlik Answers already understands a remarkable amount of business language. But like any intelligent tool, the quality of its answers depends on the quality of what it has to work with. A data model with ambiguous field names or undocumented metrics might work fine when a developer manually hand-picks the right fields for a chart - but when an AI resolves a natural language question against that same model, those small inconsistencies start to matter.
Here’s a quick example. When someone asks “What’s our discount rate?”, Qlik Answers intelligently maps that question to fields in your semantic layer. If your model exposes Discount_Amount, Discount_Amount_Final_V1, Discount_Amount_Final_Sep24, Discount_Value, Discount1, and Discount2, the engine has to make a choice, and without clear naming, even the smartest AI can’t be sure which one you intended. It’s a signal that the model could use a little attention.
The great news is that with some straightforward preparation, you can unlock the full potential of Qlik Answers and give your users an experience that feels almost magical. This guide walks you through exactly how to get there.
If you’ve configured Business Logic for Insight Advisor before, you might be wondering: “Do I need to do all of that again?”
No - and that’s one of the best things about Qlik Answers. It uses an LLM-based approach that already understands common business language out of the box. Terms like “sales,” “revenue,” “customer,” “average,” and “quarter” just work. Standard aggregations, temporal concepts, and general business vocabulary are understood without any configuration on your part.
Where Qlik Answers benefits from your help is with your organization’s specific context. It doesn’t yet know that Discount1 is actually a coupon discount and Discount2 is a loyalty discount. And it can’t tell which of your three revenue fields is the current authoritative version. That is the context only you can provide.
With a few focused preparation steps, you’ll set Qlik Answers up to deliver accurate, trustworthy results from day one.
Three things worth doing before diving into your data model:
This tends to be the highest-impact change you can make. Ambiguous field names are the most common cause of incorrect field selection.
For every group of similarly named fields, ask: do these represent different business concepts, or are they redundant versions of the same thing?
If they’re different concepts, give them distinct, business-aligned names:
| Before | After |
|
Discount_Amount, Discount_Value, Discount1, Discount2 |
Product Discount, Promotional Discount, Coupon Discount, Loyalty Discount |
If they’re redundant versions, pick the authoritative one, create a master measure if the calculation is complex, and hide the rest using Business Logic visibility controls.
Naming principles:
Every visible field is a candidate answer to a user’s question, so fewer irrelevant fields means fewer wrong answers. A streamlined model is also faster to index.
Hide technical fields. In Business Logic → Logical Model → Visibility, set these to Hidden:
Consolidate redundant fields. If your model has Revenue_Old, Revenue_New, and Revenue_Current, users asking about “revenue” will get inconsistent results. It’s worth picking the authoritative version and hiding the rest.
Hidden fields remain fully functional for calculations, expressions, and existing charts. You’re only removing them from the Qlik Answers query scope, so nothing breaks.
Time-based queries are among the most common in natural language analytics (“revenue by month,” “trends over time,” “compare this quarter to last”). If your date fields are loaded as plain text, Qlik Answers won’t recognize them as dates. That means no auto-calendar, no chronological sorting, and no correct time-based analysis.
In Data Manager or Model Viewer, check the tags on every date-related field. You want Date or Timestamp tags. If you see $ascii or Text, fix it in the load script:
Date(Date#([SourceDateField], 'MM/DD/YYYY')) as [Order Date]
Timestamp(Timestamp#([SourceTimestamp], 'MM/DD/YYYY hh:mm:ss')) as [Order Timestamp]
After fixing, test with queries like “Show me trends over time” and “Sales by month” to confirm the engine applies chronological logic correctly.
Master items are one of your strongest levers for improving Qlik Answers accuracy - and this is where the platform really shines. When processing questions, Qlik Answers intelligently gives greater weight to master items than to raw fields in the data model, because it recognizes that master items represent curated business intent. It’s a great example of how the engine is designed to work with you.
For each of your top metrics, create a master measure with a validated expression and a clear description. The description matters - Qlik Answers uses it to understand context and match user intent. A good description explains what the metric measures, how it’s calculated, and when to use it.
For detailed guidance on writing effective master item descriptions, see the help documentation: Writing master item descriptions for Qlik Answers.
Qlik’s Business Logic vocabulary feature lets you define synonyms and map business terms to fields. It’s a useful tool, though you may need less of it than you’d expect. Because Qlik Answers is powered by an LLM, it already has a strong grasp of standard business terms: “sales,” “revenue,” “customer,” “average,” and “quarter” all work right out of the box. You only need to step in for the terminology that’s unique to your organization.
Where vocabulary adds value:
What to watch out for:
Configure in Business Logic → Vocabulary. Map each synonym to a specific field or master item, and test with queries using those terms to confirm the mapping resolves correctly.
It’s helpful to run representative queries across these categories and verify the results:
| Category | Example queries |
|
Basic aggregations |
"Total revenue," "Customer count," "Average order value" |
|
Time-based |
"Revenue by month," "Sales trends over time," "Compare Q3 to Q4" |
|
Filtered |
"Revenue for Product X," "Customers in Region Y" |
|
Comparative |
"Top 10 customers by revenue," "Highest margin product?" |
| Vocabulary
|
"Show me CAC," "What’s our churn rate?" (if configured) |
Use the reasoning panel. In the Source tab, click View Reasoning to see exactly which fields the engine selected and why. This is the fastest way to diagnose incorrect results and trace them back to a semantic layer issue.
For each test query, check:
If a query doesn’t resolve correctly:
You don’t need a perfect data model to get great results from Qlik Answers. You just need a clear one.
There’s no need to define what “revenue” or “quarter” means. By making sure your model is unambiguous, your dates are properly typed, your key metrics are defined, and your field list is clean, you’re giving Qlik Answers everything it needs to deliver the kind of instant, accurate insights your business users have been waiting for.
These are established data modeling best practices that have always mattered — Qlik Answers just makes the payoff more immediate and visible. Invest a little time in preparation, and you’ll be amazed at what your users can accomplish.
For the complete technical reference, including detailed guidance on field naming conventions, master item descriptions, and synonym configuration, see the official documentation: Best practices for preparing applications for Qlik Answers.
After upgrading to Qlik Talend Cloud Enterprise Edition R2025-08, some users reported that the tClaudeAIClient component was missing from the Talend Studio Palette.

This article covers how Talend Real-time Big Data can be used to effectively leverage Talend’s Real-time Data processing and Machine Learning capabilities. The use case handled in this article is how Twitter data can be processed in real time, and classify if the person tweeting has post-traumatic stress disorder (PTSD). This solution can work for any major health situation of a person, for example cancer, which is discussed at the end.
PTSD is a mental disorder that can develop after a person is exposed to a traumatic event, such as sexual assault, warfare, traffic collisions, or other threats on a person's life.
Considering the high increase in the end users of the social networks, we expect a humongous amount of data written every day into social networks. To handle such a huge amount of data, we need a Hadoop Ecosystem. Hence, this use case of PTSD is classified as a Big Data use case, as Twitter is our data source.
| Spark Framework Apache Spark™ is a fast and general engine for large-scale data processing. |
Random Forest Model Random forest is an ensemble learning method for classification, regression, and other tasks, that operates by constructing a multitude of decision trees at training time and outputting the class that is the mode of the classes (classification) or mean prediction (regression) of the individual trees. |
| Hadoop Cluster (Cloudera) A Hadoop cluster is a special type of computational cluster designed specifically for storing and analyzing huge amounts of unstructured data in a distributed computing environment. |
Hashing TF As a text-processing algorithm, Hashing TF converts input data into fixed-length feature vectors to reflect the importance of a term (a word or a sequence of words) by calculating the frequency that these words in the input data appear. |
| Talend Studio for Real Time Big Data Talend Studio to perform MapReduce, Spark, Big Data real-time Jobs. |
Inverse Document Frequency As a text-processing algorithm, Inverse Document Frequency (IDF) is often used to process the output of the Hashing TF computation in order to downplay the importance of the terms that appear in too many documents. |
| Kafka Service Apache Kafka is an open-source stream processing platform written in Scala and Java to provide a unified, high-throughput, low-latency platform for handling a real-time data feed. |
Regex Tokenizer Regex tokenizer performs advanced tokenization based on given regex patterns. |
Talend Studio not only supports Talend’s own components, it also supports the custom-built components from any third parties. All these custom-built components can be accessed from Talend Exchange, an online component store.
To perform all of the above, we need to get access to the Twitter API.
Deciding which hashtags to use plays a vital role. We may use a single hashtag, or a combination of multiple hashtags to pull the accurate data required. Choosing appropriate hashtags helps to filter the large volume of source data.
As we all know, nothing can be done without human intervention. Once the data pulled from Twitter is in place, we need to manually classify the tweets as Having PTSD or Not Having PTSD.
Classification can be done by adding a new attribute to that data. Values can be Yes or No (Yes – having PTSD, No – Not having PTSD). Once the classification is done, we can call this data as a training set that can be used to create and train the model.
To achieve our use case, before creating the model, training data needs to undergo some transformations such as:
After passing through all the algorithms above, training data can be passed into the model to create and train it. The model that suits this prediction use case best is the Random Forest Model.
Talend Studio for Real-time Big Data has some very good machine learning components that can perform regression, classification & prediction using Spark Framework. Leveraging the capability of Talend to handle machine learning tasks, the Random Forest Model has created and trained the model with the training data. Now we have the model ready to predict the tweets.
Note: All the work is done on a Cloudera Hadoop Cluster, Talend is connected to the cluster, and the rest of the computation is achieved by Talend.
Now we have the model ready on our Hadoop cluster. We can use the process in step 1 and pull the data from Twitter again, which acts as a test data. The test data has only one attribute: Tweet.
When the test data is passed to the model we have created, the model adds a new attribute Label to the test data, and its value will be Yes or No (Yes – having PTSD, No – Not having PTSD). The predicted value depends solely on the way the model is trained in step 2. Again, all this prediction can be done in Talend Studio for Real- time using Spark framework.
Once the model predicts the classification of the test data set, we find the records to be 25% erroneous (on average). We need to assign the right classification to that 25% of the records, add them to the training set, and retrain the model. It should predict accurately now. Add more records to the training set, and repeat the same procedure until the model becomes accurate. A model needs to evolve over time, by training it with newly added training data that comes with time. Some management is required.
Note: To boost the effectiveness of the model, we can add synonyms of the training data to the training set and retrain the model, which leads to developing the model synthetically rather than just organically.
A threshold of 90% accurate predictions is a must to classify the model as accurate. If the prediction accuracy level drops below 90%, then it is time to retrain the model.
| Application 1 When a tweet is classified as Yes (having PTSD), we can hand over the Twitter handle name of the person to any social welfare organization, so that they can reach out to that person via Twitter and offer services such as social activities, support groups, etc. |
Application 3 Conduct research and analysis into medication provided to PTSD-affected patients, and provide the results to pharmaceutical companies and the FDA. Evaluate treatment given to these patients, and redirect them to appropriate/better healthcare providers. |
|
| Application 2 Health care clinics can reach out directly to the person suffering from PTSD, understand the patient's present stage of the treatment, and provide better healthcare services. |
Application 4
Adding sentiment analysis as an extension to this proof of concept can lead to much more useful real-time applications to provide mental health support. |
Note: Once the classification of data is done (Yes or No), it may lead to many more useful real-time applications.
The use case solution designed can work for any of the major health situations. For example, if the use case is with cancer, using cancer-specific hashtags we can train the model in an equivalent way and start predicting if the person has cancer or not. The same real-time applications as discussed above can be achieved.
