A Text Similarity Meta-Search Engine Based on Document Fingerprints and Search Results Records

The retrieval of similar documents from the Web using documents as input instead of key-term queries is not currently supported by traditional Web search engines. One approach for solving the problem consists of fingerprint the document’s content into a set of queries that are submitted to a list of Web search engines.
