Patent ID: 8271483

Claim:
A computer-executed method for detecting sensitive content in a document, the method comprising: receiving a document; identifying a set of terms in the document; generating a combination of terms, based on the identified terms, that is associated with a semantic meaning and is potentially sensitive; performing a first search through a public corpus for the combination of terms and determining a first search hit count returned for the combination; performing additional searches through the public corpus for individual terms in the combination and determining search hit counts returned for each term in the combination; computing a search hit ratio between the first search hit count and the average search hit count for the individual terms in the combination; in response to the computed search hit ratio being smaller than a predetermined value, labeling the combination of terms as sensitive; and generating a result that indicates portions of the document which contain sensitive combinations; determining a relationship between the identified terms by processing the document with a syntactic parser to determine relationships between the terms; wherein determining the relationship between the identified terms further comprises scoring a respective relationship based on a determined relevance to the document and a likelihood of the terms being sensitive.
