Extract salient words with WordRank for effective similarity search in text data

We propose a method named WordRank to extract a few salient words from the target document and then use these words to retrieve similar documents based on popular retrieval functions. The set of extracted words is a concise and topic-oriented representation of the target document and reduces the ambiguous and noisy information in the document, so as to improve the retrieval performance. Experiments and results demonstrate the high effectiveness of the proposed approach.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000233809200054&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Computer Science, Information SystemsComputer Science, Theory & MethodsSCI(E)CPCI-S(ISTP)
