Log-Aided Automatic Query Expansion Based on Model Mapping

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a device to cause the device to:

• generate a vector representation for each of multiple words derived from historical user queries, wherein each of said vector representations is based on one or more system logs;
• generate a vector representation for each of multiple documents in a corpus of documents related to solutions to one or more hardware problems and/or one or more software problems;
• generate a vector representation for a user query based on the generated vector representation for each of the multiple words derived from the historical user queries;
• compare the vector representation for the user query to the vector representation for each of multiple documents in the corpus;
• and
• determine one or more documents from the corpus to output in response to the user query based on said comparing.

A system comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured for:
• generating a vector representation for each of multiple words derived from historical user queries, wherein each of said vector representations is based on one or more system logs;
• generating a vector representation for each of multiple documents in a corpus of documents related to solutions to one or more hardware problems and/or one or more software problems;
• generating a vector representation for a user query based on the generated vector representation for each of the multiple words derived from the historical user queries;
• comparing the vector representation for the user query to the vector representation for each of multiple documents in the corpus;
• and
• determining one or more documents from the corpus to output in response to the user query based on said comparing.

A computer-implemented method, comprising:

• generating a vector representation for each of multiple words derived from historical user queries, wherein each of said vector representations is based on one or more system logs;
• generating a vector representation for each of multiple documents in a corpus of documents related to solutions to one or more hardware problems and/or one or more software problems;
• generating a vector representation for a user query based on the generated vector representation for each of the multiple words derived from the historical user queries;
• transforming the vector representation for the user query to a space associated with the corpus by implementing a transformation function trained via the corpus;
• comparing the transformed vector representation for the user query to the vector representation for each of multiple documents in the corpus;
• ranking the documents from the corpus based on said comparing;
• and
• outputting one or more documents from the corpus in response to the user query based on said ranking;
• wherein the steps are carried out by at least one computing device.
