Exporting from nbdev

In the first example, neither the FAQ or context datasets have samples. After the first context is added, it appears as a reponse to the typed answer. The second example adds a new question-answer pair. The context of the first example also provides an answer.

Technologies

The Chatbot is based on two types of question/answer models:

  1. Question Answering Model for SQuAD dataset
  2. Knowledge Base Question Answering

The first type of models can answer several questions from the same context, while the second type is very useful for specific and complex questions. It is strongly recommended to consult the deeppavlov library for further details of the available models for dialog systems.

Structure of the Package

The package let_me_answer_for_you consists of three modules: settings, dialog_system and chatbot.

The chatbot.py file of the repo, calls the ChatBot class in chatbot and is the child of the DialogSystem class in dialog_system. This last class has the three main methods of the library:

  1. question_answering
  2. new_question_answer
  3. new_context

The first method retrieves a set of answers for a given question. The second method adds a new question-answer pair to the FAQ data and retrains the model. The third method adds a new context to the context data. These are the methods that may be exported as the API calls.
