# What for ?


In the “KB” tab you can configure all the questions you want the chatbot to answer as well as the expected answers.

Building a knowledge base means answering the following questions:

  • What should my chatbot answer?

  • Who are the users of my chatbot?

Before starting to build your knowledge base, please read the technical limitations .

# Import

If you already have a knowledge base, for example several questions and answers from a FAQ, you can import this data into the platform. The file must be in Excel format and follow this specific form:

  • Column 1: Questions
  • Columns 2: The answers
  • Alternatives: below the “principal” question. The altenative will be different than the e the same.

📖 What is a “principal” question?

    • Click on "Add a new fact" if you want to add an additional element
  • ColumnSet: It is possible to put several columns and thus add one element among "Elements" per column (text, image, media...)

# ELEMENTS

  • Rich TextBlock: use the JSON editor to edit text
  • Image: ⚠️ add the URL of the image you want to add
  • Media: It is possible to add a video but it will only be available on the Webchat (the media element is not available for the Teams channel)

It is also possible to create an Adaptive Card using a JSON code. To do this, click on "JSON" at the bottom left of the page.

To start the conversation tree, the new question is displayed in the first shape. Each shape corresponds to a chatbot message.

This first shape is the only one with text (the question) in the colored strip.

You can now start building your tree. To this, first create your boxes.

⚠️

In case you want to add a conversation tree to your knowledge base and the latter already contains a large number of questions with simple and contextual answers, the training (i.e. synchronization) can be longer. Click on "Train" and wait until the button is greyed out, before continuing to build your knowledge.

# Witivio shape

  • Bot Message: this shape corresponds to a bot message

# Alternatives

An alternative is a reformulation of the principal question. The number of alternatives to a main question is displayed below on the right.

low score

If you select a template when creating the question , it will have several alternatives automatically.

🔴

These alternatives created automatically, called "simple" alternatives are rewording of the main question, using the same words. Only users can provide the chatbot with "complex" alternatives. The latter are formulated differently but lead to the same answer.

Example :

  • Main question : Where can I find the reset password process?
  • Simple alternative : Where are the reset password process?
  • Complex alternative : I forgot my password, how can I reset it?

💡 Good practices

A main question must have at least 5 complex alternatives and the maximum number of altenatives is 99 (simple+complex) .

Click on the altenatives to add new ones or delete. You can use Free text or templates to add alternatives. Tick one or several alternatives to delete them (trash icon).
