Abstract

Techniques for prevalence-volume based relevance are provided. Corresponding systems and methods may include ingesting a corpus of documents; receiving a search operator; segmenting the corpus of documents into (i) a first set of documents that matches the search operator, and (ii) a second set of documents that do not match the search operator; extracting a first and second token list of tokens; calculating a prevalence-volume value for tokens included in the first and second token lists; generating a prevalence-volume ratio (PVR) matrix that associates tokens included in the first and/or second token lists with a PVR value, wherein the PVR value for a particular token is a ratio between the prevalence-volume value of the particular token for the first set of documents and the prevalence-volume value of the particular token for the second set of documents; and associating the search operator with the generated PVR matrix.

Dependent claims

A computer-implemented method comprising:

ingesting, via one or more processors, a corpus of documents;
receiving, via the one or more processors, a search operator;
segmenting, via the one or more processors, the corpus of documents into (i) a first set of documents that matches the search operator, and (ii) a second set of documents that do not match the search operator;
extracting, via the one or more processors, (i) a first token list of tokens included in the first set of documents and (ii) a second token list of tokens included in the second set of documents;
calculating, via the one or more processors, a prevalence-volume value for tokens included in the first and second token lists;
based on the calculated prevalence-volume values, generating, via the one or more processors, a prevalence-volume ratio (PVR) matrix wherein the PVR matrix associates tokens included in the first and/or second token lists with a PVR value, wherein the PVR value for a particular token is a ratio between the calculated prevalence-volume value of the particular token for the first set of documents and the calculated prevalence-volume value of the particular token for the second set of documents;
and
associating, via the one or more processors, the search operator with the generated PVR matrix.

5 more elements

A system comprising:

one or more processors;
and
one or more non-transitory memories coupled to the one or more processors and storing processor-executable instructions thereon that, when executed by the one or more processors, cause the system to:
ingest a corpus of documents;
receive a search operator;
segment the corpus of documents into (i) a first set of documents that matches the search operator, and (ii) a second set of documents that do not match the search operator;
extract (i) a first token list of tokens included in the first set of documents and (ii) a second token list of tokens included in the second set of documents;
calculate a prevalence-volume value for tokens included in the first and second token lists;
based on the calculated prevalence-volume values, generate a prevalence-volume ratio (PVR) matrix wherein the PVR matrix associates tokens included in the first and/or second token lists with a PVR value, wherein the PVR value for a particular token is a ratio between the calculated prevalence-volume value of the particular token for the first set of documents and the calculated prevalence-volume value of the particular token for the second set of documents;
and
associate the search operator with the generated PVR matrix.
