Combo of language understanding and information retrieval

An apparatus for information retrieval, comprising:

• a receiving module configured for receiving a query in a natural language form from a user;
• an extracting module configured for extracting a plurality of feature vectors from the query based on words in the query that match words in 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 wherein the plurality of knowledge entries comprise reminders previously provided by the user;
• an obtaining module configured for obtaining, with a pre-trained language understanding model, a plurality of language understanding results based on the plurality of feature vectors;
• and
• a selecting module configured for selecting a knowledge entry corresponding to the query among the plurality of knowledge entries based on the plurality of language understanding results.

A computing system, comprising:

• one or more processors;
• and
• a memory, storing computer-executable instructions that, when executed, cause the one or more processors to perform
• receiving a query in a natural language form from a user;
• extracting a plurality of feature vectors from the query based on words in the query that match words in 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 wherein the plurality of knowledge entries comprise reminders previously provided by the user;
• obtaining, with a pre-trained language understanding model, a plurality of language understanding results based on the plurality of feature vectors;
• and
• selecting a knowledge entry corresponding to the query among the plurality of entries based on the plurality of language understanding results.
