Microsoft patents AI system to extract dates from text queries
Microsoft has filed a patent for a system that uses machine learning to find and interpret dates within user queries. The system breaks down text into parts, focuses on time-related phrases, and converts them into a specific day, month, and year format for other software to use.
In the filing’s own words
A computing system including one or more processing devices configured to receive an input query. At a query parsing machine learning (ML) model, the one or more processing devices extract a temporal substring from the input query. At a sentence embedding ML model, the one or more processing devices compute a sentence embedding of the temporal substring. At a date classifier ML model, the one or more processing devices compute a date embedding based at least in part on the sentence embedding and perform classification on the date embedding to identify an output date including a day, a month, and a year indicated by the temporal substring. The one or more processing devices output the output date to an additional computing process.
What exactly they claim (claim 1)
1. A computing system comprising: one or more processing devices configured to: receive an input query; at a query parsing machine learning (ML) model, extract a temporal substring from the input query; at a sentence embedding ML model, compute a sentence embedding of the temporal substring; at a date classifier ML model: compute a date embedding based at least in part on the sentence embedding, wherein computing the date embedding includes upscaling an embedding space region of the sentence embedding ML model that encodes date-related semantic information; and perform classification on the date embedding to identify an output date including a day, a month, and a year indicated by the temporal substring; and output the output date to an additional computing process.
