Notes:
The question classifier module is a component of a dialog system that is responsible for identifying the type or category of a given question. This module typically receives the user’s input in the form of natural language text, along with any additional context or information that the system has about the user or the current conversation. It then uses natural language processing techniques to analyze the input and determine the type or category of the question.
The question classifier module typically includes a set of rules or algorithms that define how the system should classify different types of questions. For example, the module may use rules to identify common patterns and structures in questions, such as the use of specific words or phrases, or the presence of particular grammatical constructions. It may also use algorithms to identify the underlying intent or purpose of the question, such as whether it is asking for information, seeking confirmation, or requesting an action.
Once the question has been classified, the module generates a set of intermediate representations of the question’s type or category. These representations may take the form of labels or tags, such as “factual” or “opinion,” or more detailed descriptions of the question’s intent or purpose. These representations can then be used by other modules in the system to generate appropriate responses or actions.
Overall, the function of the question classifier module is to help the dialog system identify the type or category of a given question. This can help improve the system’s ability to interpret and respond to a wide range of user input, and make the interaction more natural and effective for the user.
