/ A MANAGEMENT APPARATUS FOR STORING INDICES IN INFORMATION RETRIEVAL SYSTEM AND THEIR STORAGE/RETRIEVAL METHOD

摘要

1. the art that the invention defined in the claims; The present invention will on the lower storage structure management device and a data storage / retrieval method of the IR system.; 2. The invention attempts to solve the technical challenges; Search the invention the information that, by improving the efficiency of storage space for the document to dynamically generated using the inverted file structure of the dual structure managed by storing the structural information of compound nouns separately to avoid redundant storage of information, improving the reliability of the search to provide a computer readable recording medium recording a program for realizing the structure of the lower storage management device and a data storage / retrieval system and method of the above method that its purpose.; 3. Resolution of the subject matter of the invention,; The present invention, a first step of separating the compound nouns query with a simple noun; Using a discrete simple noun second step of extracting the stored information; Using the location information of the extracted index information, a third step of extracting the index list of documents; A fourth step of extracting structure information for each simple noun; And By implemented to include a fifth step of generating a search using the index information and structure information extraction result for each simple noun, using an inverted file structure of a dual structure with a variable storage space in accordance with the occurrence frequency of each index term assigned efficient processing of an increasing index, and further index term structure by using the information and extracts the location information and managed separately from the search to reduce the redundancy of the stored information in accordance with the part matching the support of compound nouns the search efficiency in accordance with the part matching the enhance, and improve the reliability of the search by reflecting the results for your search.; 4. An important use of the invention,; Search the invention is applied to the lower storage structure of an information retrieval system such as a digital library.
