A New Method of Document Management for Information Sharing Systems

摘要

The importance of sharing information on corporate LAN system has been pointed out for years, and many information sharing systems are currently up and running. However, users are not really satisfied with the current systems because 1) it requires a lot of labor to register the data to be shared, and 2) it is difficult to find the registered information efficiently because of mistakes on classifications. This paper proposes a information sharing system which has resolved these problems. This system allows users to register shared information only by dragging and dropping it into shared folders and automatically rearranges the registered information. To implement these features, we propose the methods to automatically extract and learn the keywords which used to be registered by users manually, to automatically cluster the learned keywords into categories, and to improve the search efficiency. We have evaluated our system using data of a search engine, Hi-Ho e-search, and have accomplished reproduction of 104 categories out of 125 (83.2%).
