THREE-DIMENSIONAL LATENT SEMANTIC ANALYSIS

摘要

In some examples, a computing system may access multiple information files, generate term-passage matrix data based on the multiple information files, and decompose the term-passage matrix data to generate a reduced-dimensional semantic space, which may be used for information retrieval.

主权项

1. A method comprising:
accessing, by one or more processors, a plurality of information files; generating, by the one or more processors, term-passage matrix data based on the plurality of information files; and decomposing the term-passage matrix data to generate a reduced-dimensional semantic space, wherein a number of rows of the term-passage matrix data corresponds to a sum of a number of distinct words in the plurality of information files and a number of distinct word pairs in the plurality of information files, and wherein a number of columns of the term-passage matrix data corresponds to a number of passages in the plurality of information files.
