| Research Abstract |
This research has constructed an information retrieval system based on Z39.50. Z39.50 is a standard information retrieval protocol in ANSI and ISO, which defines data structure and data processing between servers and clients. Information retrieval systems based on Z39.50 allow users to connect the other Z39.50 systems in the world, and to share information resources. The present system consists of a client and a server. The client allows users to input words for retrieval in Japanese, and displays Japanese characters. The server consists of control module, protocol module, retrieval engine, and database. The database consists of indices and Japan/MARC records. Japan/MARC records are converted to plain text files which one record corresponds to one file. The number of the records is 1,019,696, which are from 1983 to 1998. Index terms are generated by the "CHASEN" which is a Japanese text processor. Indexing is processed by the "NAMAZU" which is a Japanese text indexer. This research concludes that the system allows users to share information resources on the Internet.
