Bot knowledge base

The knowledge base is a set of chatbot or voice assistant modules. Through the use of modules, chatbots can better understand customers and achieve various business goals.

The main advantage of the knowledge base is its simple user interface, through which you can easily control the bot modules and customize them to suit the project’s needs. This tool is primarily aimed at conversational AI development team members whose work does not directly involve technical tasks, such as writing code or fine-tuning the classifier.

Getting started​

  1. Create a new JAICP project or select an existing one.

  2. On the control panel to the left, select Knowledge base.

  3. Create the first module in your project.

    Selecting and adding a new module

The project knowledge base can consist of multiple modules.

You can manage these modules through the knowledge base menu and the tab bar. On this page, you can add new modules and switch between them. Right-click a tab with a module to rename it, disable or re-enable it, or else delete the module entirely.

What is a module​

A knowledge base module is a set of bot functions which share a common use case or a problem they help solve. There are two ways to manage knowledge base modules:

  • Manually add sets of frequently asked questions and answers (FAQ).
  • Attach documents where your bot can look for answers to set questions (CDQA).

Modules may enable the bot to:

  • React to spontaneous customer queries — this is usually referred to as “chit-chat”.
  • Respond to questions on specialized topics, such as the banking services your company provides.

Future versions of the knowledge base will also support modules which will be able to trigger their own separate scripts inside the main bot: for example, set an alarm by the customer’s request and set it off at the scheduled time.

tip
The central part of any module is its natural language understanding (NLU) component, which allows the bot having a certain module to understand user requests.

The NLU part of knowledge base modules is implemented through CAILA — the NLU core of JAICP. If the features of the knowledge aren’t enough for you, you can switch to CAILA and carry on your work in the intents interface. Navigate to CAILA → Intents and find an intent named KnowledgeBase in the intents tree. Each of its nested intents corresponds to one of the modules in the current project.

Module testing​

While working on the knowledge base, you can verify if questions within phrases are recognized correctly. In the top right corner, select:

  • Apply and test — this will apply the latest changes in the knowledge base, then open the test widget.

  • next to *Apply and test* → *Open the test widget* — in this case, the changes will not be applied.
    tip
    This option may come in handy when you need to check the behavior of the previous knowledge base version after you’ve already made changes to it.

Test widget​

The knowledge base shares its test widget with CAILA, which is why the test output contains all intents (including questions from FAQ modules) and entities recognized in the current project.

  • If CAILA detects a question that triggers an FAQ module, this question is displayed as an intent. Each recognized intent has a corresponding score in the interval from 0 to 1 — the level of confidence that the phrase contains it.
  • If a phrase has a question that the CDQA has an answer to, the widget will show this answer above the list of intents. Click on it to learn more about how the model has processed the question: its confidence value and the list of other possible answers with a lower score.

When prompted with the phrase “Branch offices”, the test widget displays a list of suitable intents with various scores. When prompted with the phrase “What is the knowledge base?”, the test widget a card with a CDQA response.

Applying changes​

To apply the latest changes in the knowledge base, select either Apply and test or  → Apply changes (this will not open the test widget).

caution
After applying the changes, they are immediately made available in all channels where the bot is deployed. During active development, it is recommended to test modules in a separate project before importing them to the primary one.

Module extension​

JAICP offers built-in tools to help you expand your knowledge base and prepare it for bot training.

The bot is trained on the contents of the FAQ modules. These make up your training set. To help the bot understand user requests better, the training set needs to be processed and expanded with data the bot will encounter when communicating with users.

tip
For practical recommendations on how to improve set quality, see How to train intents.

To use the tools, select and go to the knowledge base menu.

Here you can:

  • Add module.

  • Set up search for matches.

    Use this to avoid duplicates as well as similar questions and answers. If you don’t filter it out, the bot may answer the wrong question during a dialog.

  • Use fine-tuning.

    Use this you to update modules with questions and alternative phrases from previous user conversations. Fine-tuning will be useful if you’re using the bot long enough and it has collected enough conversation data.

    caution
    By default, fine-tuning is disabled. To access it, send a request to our customer support.
