Abstract
Official abstract text for this publication.
An equivalence determination system ( 10 ) according to this invention includes a specifying means ( 11 ) and determination means ( 12 ). The specifying means ( 11 ) specifies parts of respective electronic documents in a document database that are rarely modified manually. The determination means ( 12 ) determines whether the parts specified by the specifying means ( 11 ) match each other between a plurality of electronic documents, and when determining that the parts match each other, specifies that these documents are a plurality of similar electronic documents. An electronic document which cites part or all of another electronic document and is slightly modified can be quickly specified in the document database.
First claim
