Mis on NLU ja millised on selle alamülesanded (tahe, slotid, entiteedid)?

NLU (Natural Language Understanding) is a field of natural language processing responsible for understanding the meaning of user queries.

Main sub-tasks of NLU:

• Intent recognition — determining the goal or task the user wants to perform (e.g., "order a taxi" or "find out the weather").

• Entity recognition — identifying key objects or concepts in the query, such as names, dates, locations.

• Slot filling — extracting and structuring the parameters needed to fulfill the intent. For example, for the intent "order a taxi", slots might be: departure address, destination address, time.

These components together enable the system to understand exactly what the user wants and what data is needed to process the request.
