RETRIEVAL RANKING METHOD FOR FILE SYSTEM, AND RELATED RETRIEVAL ENGINE

摘要

PPROBLEM TO BE SOLVED: To provide a retrieval ranking method suitable for a file system. PSOLUTION: This retrieval ranking method for the file system includes receiving a retrieval expression (a query), computing final adaptability scores of individual file items to the retrieval expression at least according to the energy scores of individual nodes on a present file system - energy tree to output a list of retrieval results based on the final adaptability scores, and updating the file system - energy tree in response to operation performed by a user to the file system. The file system - energy tree has a tree structure corresponding to the tree structure of the file system, and the individual nodes correspond to the individual file items of the file system. A file and a file folder in which the user is interested are usually arranged in the relatively high positions in the retrieval result list of file system retrieval. Further, as the user's clicks to the file increases, the retrieval result list is dynamically adaptable to the change of the user's interest and preference. PCOPYRIGHT: (C)2008,JPO&INPIT
