  • Generating a fingerprint for a document
    Patent number: 7555489
    Abstract: Mechanisms for generating a set of one or more elements of a fingerprint for a document, the document comprising a semantic construct having one or more ordered words, are provided. With these mechanisms, a range of sizes for a fingerprint element is defined and ordered words of the semantic construct are divided into a set of one or more mutually exclusive fingerprint elements. Each of the one or more mutually exclusive fingerprint elements includes a number of adjacent words, the number being within the range of sizes for a fingerprint element. Responsive to a determination that the set of mutually exclusive fingerprint elements excludes a word from the semantic construct, the excluded word is discarded.
