| Research Abstract |
WWW contents are very important resources in Japan from the point of country resources view, so these contents are expected to be useful and efficient for our key industries. However, the WWW contents are only utilized for keyword search on commercial search engines at this time.
Our research goal is constructing high performance platform which provides the feasible access to Web contents in order to study novel search methods on WWW. So, we researched a novel system architecture which is appropriate for large data intensive processing, intelligent data management methods for searching large collected Web pages and log analyzing methods for providing an efficient utilization of Web-ware houses.
1) A large scale system architecture for Web-ware houses : we proposed the PC cluster systems with many disks connected by SAN ( Storage Area Network), that is, SAN PC cluster. The prototype system is implemented and evaluated with large data mining query. The evaluation results show our proposed system is effective for storing and processing large scale data such as WWW contents.
2) Data management methods for intelligent processing a large volume of WWW pages : we employed a novel approach based on hyper link information amongst WWW pages. This approach is completely different from previous methods. By using the proposed approach, we extracted a community chart from the whole Japanese WWW pages which are collected and stored into our PC cluster system and made a WWW map. Then, we provided a visualization tool supporting to search and show a various relationship among extracted communities.
3) WWW access log analysis methods : we analyzed WWW access log to investigate user's behavior and to reflect analyzed results to systems such as e-commerce site, WWW store and so on. Then, we could extract typical user's behavior pattern from global WWW log ( panel logs ).
