The NER (Named Entity Recognition or Extraction of Named Entity) is the mechanism of automatic language processing to detect and extract them.

How to use an entity?

If you want to use them in natural language

In the training sentences of your intention, you will need to make the connection between the training sentences and your entities. To do this, simply annotate like the screenshot below. You can use entities for several reasons:

  1. You want to detect all possible occurrences of a particular word in an intention.
    • Example with this chatbot which puts you in touch with producers where it is possible to detect different products such as vegetables, meat, cheese, strawberries, etc ...
  2. You want to know if a particular word (a variable) is present or not in a sentence.
  3. Entities influence the interpretation of intention. This helps to reduce the number of intentions and avoid close intentions. Refer to the confusion matrix to optimize the operation of your chatbot with entities.
