Setting up the training-tutorial project for Technical BA Academy
FAQ relevant for: Technical BA Academy Hi Guys! Some good news for all of you doing the Technical Business Analyst Academy! We've added a new script to your VDIs to simplify the training-tutorial project setup. This script combines all the necessary setup commands into a single script! If you've already set up the training-tutorial project, there's no need to do it again! Also, you will still be able to setup the project manually by following BA Module 1.2: Smoke Test (after completing Module 1.1: Development Tools). The new script is just an additional method for setting up the training-tutorial project for the Scenario-based Tasks. The rest of this post will explain how to get the new script on your VDI, and how to use it to set up the training-tutorial project. How to get the updated setup scripts To add the new script to your VDI, you will need to unzip the setup scripts again. To do this run the following commands in order: cd ~ cp /opt/training/other-resources/setup-scripts/tba-academy/setup_scripts.zip ~ unzip setup_scripts.zip cd ~/setup-scripts-analyst/ chmod +x *.sh If you are prompted with this message: Enter A (or y) to overwrite the existing setup scripts folder with the new folder. Things to Check: Make sure you have the correct setup scripts: Open the /setup-scripts-analyst folder. Check that the file run_training_tutorial_setup.sh is there. If the file is missing, rerun the setup scripts above. Make sure you have the training-tutorial project Check you have the /training-tutorial folder in the home directory of your VDI. If you do not have the training-tutorial project run the following commands: cd ~/setup-scripts-analyst ./run_setup.sh Running the training-tutorial setup script Now that you have the new setup script, you can use it to set up the training-tutorial project! To run the script run the following commands in order: Step 1: Navigate to the /setup-scripts-analyst folder using: cd ~/setup-scripts-analyst Step 2: Run the training-tutorial setup script using: ./run_training_tutorial_setup.sh This script may take up to an hour to fully execute all the commands. Important Note: Do not leave the VDI idle for too long as it will disconnect from inactivity! If this happens, you will need to rerun the script If all the commands execute successfully, you will see this final message in the terminal: Now you should be able to run the Quantexa UI on the training-tutorial project using the run-all script! If you encounter any issues while running this script or have any questions, please let us know in the comments of this post! We hope this helps! Many thanks, The Academy TeamFAQ: Broken Elasticsearch Head Chrome Extension Workaround
FAQ relevant for: all Academy versions Hi all, Support for Manifest V2 has officially been disabled in Google Chrome, which means the Elasticsearch Head Chrome extension is no longer functioning properly on the VDIs. When you try to add the Elasticsearch Head Chrome extension you may see the following error: "This extension was turned off because it is no longer supported" or this error: "Cannot install extension because it uses an unsupported manifest version. Could not load manifest." We are looking into ways we can resolve this issue, however for now we have a workaround to get the extension working. Error Workaround Here are the steps you can follow to work around this error: Step 1: Navigate to chrome://flags/#extension-manifest-v2-deprecation-warning in the Chrome browser: Step 2: Disable the following settings: Extension Manifest V2 Deprecation Warning Stage Extension Manifest V2 Deprecation Disabled Stage Extension Manifest V2 Deprecation Unsupported Stage Step 3: Restart Chrome. Step 4: Re-add the Elasticsearch Head Chrome extension. This comment details how to add the extension to Chrome. You should now be able to use the Elasticsearch Head Chrome extension as normal! Apologies for the inconvenience, I hope this helps!FAQ - List of Academy Frequently Asked Questions

FAQ relevant for: all Academy versions When opening IntelliJ on the Academy VDIs, dependencies may take too long to load, causing the project to not index properly. This happens because IntelliJ attempts to download dependencies but fails as the VDIs do not have access to the internet. We can stop this happening by putting Gradle in offline mode. To do this you need to do the following: First, click on the Gradle panel near the top of the right sidebar: Then, click on the toggle offline mode button: The button will be a lighter grey colour when the offline mode is on Finally, click the refresh button to restart the indexing: Your project should now index a lot quicker (although it may still take 10-20mins)!FAQ: Academy Documentation Links
Hey all! Here are some useful links for the Academies: ETL Configuring .qmodel files Configuring .qentity files Entities, Start Paths, and traversals Defining Traversals Defining Compounds Defining Elements Quantexa Core Library Core Traversals Core Elements Core Templates Address Business Individual Core Compounds Address Business Individual + Individual Synonyms Core Parsers Address Business If Business parse Business If not Business parse Individual Date to Date parts Entity Resolution Resolver Config Resolution Templates Filtered Compounds Compound Exclusions Network Generation Expansion Steps Scoring (v2.1.8) Severity Tooling Assigning Severity to a Score Configuring Score Descriptions Score Descriptions Score Description Rendering Extracting Values from Configuration files Scorecard Configuration For Comprehensions (Scala Documentation) Project Example - Scoring Best Practices UI Search Configuration Expansion Templates Traversal DSL Functions home page Example Note: The Data Engineering is currently on v2.0.1 of the Quantexa Platform and the Scoring Engineer Academy is currently on v2.1.1, however the closest documentation versions we have are for v2.0.8 and v2.1.8 respectively. These versions should be sufficient for you to complete the Academy! Please comment below if you find any other useful links from the Quantexa Documentation Site so we can add them to the list!
FAQ: Elasticsearch "cluster health: Not connected" in Chrome / "Connection refused" script error
FAQ relevant for: all Academy versions Sometimes on the VDIs you will encounter your Elasticsearch being disconnected which will then mean that the data isn't available for easy viewing and it will also lead to errors in your UI. If you try to run e.g. a load Elastic ETL script while Elastic isn't connected then you will get an error, for example: Exception in thread "main" java.net.ConnectException: Connection refused To reconnect the Elasticsearch service you just need to run the following command anywhere in a terminal window on your VDI: sudo systemctl restart elasticsearch.service

FAQ: How can I handle dates when writing a Quantexa Score in Scala?
Handling Temporal Data Temporal data refers to any data that is associated with a specific point or period in time. This includes the use of dates, times, intervals or timestamps. This information is useful for indicating when an event has occurred. LocalDate One common way of handling temporal data such as dates in your score logic is by using the LocalDate option. This is part of the java.time package. Using LocalDate allows you to manipulate dates, calculate differences between two dates, format dates into strings and parse strings into Date objects. In Scala you can also use the java.time.format.DateTimeFormatter class to format and parse temporal data into specific patterns. Here is an example below: val dateTimeFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd") The above line will help parse your dates into an appropriate format. LocalDate.parse(yourDate, dateTimeFormatter) The above line ensures that the date is parsed as a LocalDate object and would then look like this: "2024-04-17" Now that we have our localDate we can now perform operations which can be useful when writing your score logic. Commonly Used Operations Comparing dates yourDate.isAfter(anotherLocalDate) yourDate.isBefore(anotherLocalDate) yourDate.isEqual(anotherLocalDate) Extracting the month, year and day yourDate.getMonth() yourDate.getYear() yourDate.getDayOfMonth() Calculating the period between two dates To compare two LocalDates we can use the .between method after having imported the java.time.Period class. We can implement the functionality seen above to extract the period and years in the following example: val duration = Period.between(yourDate, anotherLocalDate) duration.getYears() FAQ: Type Mismatch Errors A common issue experienced in the academy is a type mismatch error when using .addRelatedDate. When using .addRelatedDate for the addition of a dynamic date field to your score, it is recommended that you use a Date type. LocalDate can still however be used within your comparison logic.FAQ - List of Academy Frequently Asked Questions

FAQ relevant for: all Academy versions If you perform a search in your UI and it only returns eg. Business entities but not Individuals or Addresses, then there are a few things you can check to resolve this issue. Firstly, remember that when you perform a general search (red box below), it will search within any field sets (orange box) you have configured in the search definitions of the resolver config. If you have configured these search definitions for all entity types, then also double check for any spelling errors in the resolver config in terms of fields that you are pointing at in the underlying data - these searches go off of fields in the cleansed Document Data Model. The other place to check is that your elastic has the data you expect in it - do you have address and individual data there? If not, then you may want to review your ETL pipeline, and check out this related FAQ. Lastly - you may need to refresh the security permissions to be able to access these additional Entities. You can do by running: ./drop_recreate_databases.sh In your home directory on the VDI (while the UI isn't running). After this, you should see the additional search fields and be able to find these entities. Let us know in a new post if you are still having issues after performing these checks!
