Details

The "Negatable" property of an Entity enables you to label Both normal (positive) and negative instances of the Entity, teach based on positive and negative models and clear the value of an existing Entity. Entities with their "Negatable" property set are called Negatable Entities in Conversation Leaner.

Steps

Start on the home page in the Web UI.

Create the Model

  1. Select New Model.
  2. Enter NegatableEntity for Name.
  3. Select Create.

Entity Creation

  1. Select Entities in the left panel, then New Entity.
  2. Select Custom Trained for Entity Type.
  3. Enter name for Entity Name.
  4. Check Negatable to enable users to provide an entity value, or say something is not an entity value thereby deleting the matching entity value.
  5. Select Create.

Create the First Action

  1. Select Actions in the left panel, then New Action.
  2. Enter I don't know your name. for Bot's Response....
  3. Enter name for Disqualifying Entitles.
  4. Select Create.

Create the Second Action

  1. Select Actions in the left panel, then New Action.
  2. Enter I know your name. It is $name. for Bot's Response....
