Abstract: The forms of library collection data are various and the data storage quantity is huge, especially for the semi-structured data with complex structure, which has brought enormous difficulties to library’s data management work. Aiming at this problem, this paper put forward a kind of intelligent retrieval system based on the semi-structured collection data of library. This system used the ontology technology to realize the feature extraction and data conversion of semi-structured collection data, and at the same time established case library by applying distributed retrieval structure based on sites to realize the multi-site retrieval and system display of user information, which can greatly reduce the operating cost of library and improve the retrieval efficiency of user information.
