Patent ID: 8380719

Claim:
A computer-based method for document searching by semantic content, comprising: receiving a user selection of a first portion of a document, the first portion comprising desired semantic content; running the document, comprising the selected first portion, through one or more classifiers to identify a first potential target document comprising a second portion; responsive to determining that the second portion of the first potential target document does not have the desired semantic content: receiving a user selection of a third portion of the first potential target document that comprises the desired semantic content; and running the first potential target document, comprising the selected third portion, through the one or more classifiers to identify a second potential target document comprising a fourth portion that has the desired semantic content; and at least one of: receiving user input comprising an indication that a second document identified by the one or more classifiers comprises the desired semantic content; receiving user input comprising an indication that the second document identified by the one or more classifiers does not comprise the desired semantic content; receiving user input comprising a selected fifth portion of the second document, the selected fifth portion comprising the desired semantic content; running a plurality of documents through the one or more classifiers until a desired document selection accuracy is reached for the desired semantic content; running the plurality of documents through the one or more classifiers until a desired number of correct documents are retrieved without an incorrect document being retrieved; running the plurality of documents through the one or more classifiers until a desired number of documents have been retrieved; using a second classifier to validate a document retrieved by a first classifier; or identifying a combination of two or more classifiers that has a desired accuracy rate for retrieving documents, and utilizing the identified combination to retrieve documents for the desired semantic content.
