Method and system for detecting undesired inferences from documents
First Claim
1. A method for detecting inferences from documents, the method comprising:
- receiving one or more documents;
extracting a first set of knowledge relevant to the documents;
formulating one or more queries to one or more reference corpora based on the first set of knowledge;
extracting a second set of knowledge from results received in response to the queries; and
producing a mapping relationship between at least one document and a piece of the second set of knowledge which is not within the first set of knowledge, the mapping relationship indicating an inference from the documents.

Abstract
One embodiment of the present invention provides a system that detects inferences from documents. During operation, the system receives one or more documents and extracts a first set of knowledge relevant to the documents. The system further formulates one or more queries to one or more reference corpora based on the first set of knowledge. The system then extracts a second set of knowledge from results received in response to the queries. Additionally, the system produces a mapping relationship between at least one document and a piece of the second set of knowledge which is not within the first set of knowledge, the mapping relationship indicating an inference from the documents.

14. A computer system for detecting inferences from documents, the computer system comprising:
-
a processor; a memory; a receiving mechanism configured to receive one or more documents; a first knowledge extraction mechanism configured to extract a first set of knowledge relevant to the documents; a query formulation mechanism configured to formulate one or more queries to one or more reference corpora based on the first set of knowledge; a second knowledge extraction mechanism configured to extract a second set of knowledge from results received in response to the queries; and a mapping mechanism configured to produce a mapping relationship between at least one document and a piece of the second set of knowledge which is not within the first set of knowledge, the mapping relationship indicating an inference from the documents. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
