Combo of language understanding and information retrieval

Abstract:

A method, an apparatus and a system for information retrieval are provided. The method for information retrieval may comprise: receiving a query in a natural language form from a user (210); extracting a plurality of feature vectors from the query based on a plurality of knowledge entries in a knowledge base associated with the user and a built-in featurization source, one feature vector per knowledge entry (220); obtaining, with a pre-trained language understanding model, a plurality of language understanding results based on the plurality of feature vectors (230); and selecting a knowledge entry corresponding to the query among the plurality of entries based on the plurality of language understanding results (240). The method may extract more features and combine information retrieval and language understanding in one shot to improve efficiency.
