I . Title Development of Science and Technology Information Service System

II. Obj ective of the s tudy and its importance The object of this project is research and develop a basic technology for efficiently performing storing and managing science and technology information which has various kinds and a huge volume. In order to accomplish this objective we divide the whole system into 3 areas of development of the electronic information service system, development of basic technology for information service and , development of basic technology for Hangul information retrieval system. Digital information service system - Developing National Innate Information System which contains research projects, academic papers, human resources, equipments related to science and technology. This can reduce the cost of edit, retrieve and service of information which have produced massively by gaining electronic information infrastructure building technique. This can also contribute the establishing joint information system by developing standard XML DTD and distribute it to related organizations. - Building and management system of the unified database system of journals, conference documents, bibliograph, title and abstract of research reports of foreign country by collection those informations effectively. Building and service the structured XML DB of bibliography and title of 15,000 kinds of imported journals. Perform SDI service when update these informations to recent one. Establishing the service system of automatic collecting possession information by linking to full- text information owner that can service it쥀 full- text. Offers a one- stop service of user- need information by realtime linking to various information such as abstract, possession, full- text, electronic journal. - Developing common XML document editing system including formula editor based on MathML for efficiently manage knowledge resources and formula representing system on the web. This makes possible the efficient generation of knowledge information resources based on XML. Developing the technology based on the information service. - Developing storage engine that can be able to support multiple language based on the unicode. Provides basic operations for managing multimedia information. Building various retrieval models for satisfy many users. Developing XML based full- text information storing & retrieval system based on all of the above techniques. - Developing libraries and distributed- systhesis information retrieval protocols that can easily retrieve information from the databases distributed various kinds of systems. Through the development of XML document editor, formula input and representation it쥀 now possible the systhesized information service system and information exchange between heterogeneous systems. This can prevents overlapped investments, increase each DB usage and makes possible a easy access to high- tech information and get a growth of economic, industrial as well as science and technology of whole nation. Development of basic technology for Hangul information retrieval system - Preventing subordination of information technology area and making basics of research for researchers in the nation by systematic access to Hangul information processing such as automatic Hangul indexing system based on unicode and apply it to science and technology term dictionary.

IV. Res ult of the study and Application schemes Development and distribution of national S&T information system Through the development and distribution of national S&T information system, we built a common academic information system between KISTI, university and research institutes. Also we built a research reports portal system by development and distribution of automatic collection management of research reports. And we built a automatic management system of academic society papers based on web- hosting and with it, we support system customizing for common utilization of the society paper information. We built a common utilization system of the academic information with link to 10 university libraries such as Hos대 univ., Hanla univ., etc. Development of the management system of foreign technology information Currently it is inconvenient for the user to access information of foreign journal because the information of bibliographs, contents and full- text requests are not linked in realtime to related institutes. It is possible now that offering full- text service and efficient information retrieval to users because journals collected by KISTI are built into the DB systematically. Development of applied XML technology It is possible now that efficient generation and representation of knowledge information resources based on XML by developing common XML document editing system including formula editor based on MathML for efficiently manage knowledge resources and formula representing system on the web. Development of the distributed- synthesized information retrieval system Distributed- synthesized information retrieval system is able to distributed information retrieval with no modification of existing various kinds of information retrieval systems. It can strengthen multi volume database site and also maintain information with it쥀 recent state. It also possible the efficient management of information resources and increase economical usage to develop and service a knowledge resources owned by each institutes by the results of various research activities to a specialized DB. The system was verified its expandability and stability by applied to the 줤cience and Technology Information Management System? It continuously developed and modified systematically the support tools based on GUI, management tool and collection and analysis function of retrieval result logs for system tuning and result merge. Development of automatic Hangul indexing system Automatic Hangul indexing system is a basis of Hangul information processing and is a necessary technique for improve information service which is a characteristic function of the KISTI. The necessary conditions of mass volume language data processing system as a key system are development of general language processing system and unique system modification and function addition as a consequence. It was developed to support unicode as a independent intellectual language processing system while provides various index type and contains many word data. Development of the English- Korean cross- language information retrieval and on- line translation system Applying on- line translation system to information retrieval system to have a information retrieval from documents made of multiple languages, It is possible th expand area of information service which is a characteristic function of the KISTI. In order to do this, we must improve the correctness of substitution word extractor. For this, it must preceded by the development of the expansion of a substitution words dictionary. This can be done by using dictionary management system. When apply on- line translation system to information retrieval system, we can provide information retrieval services with various kinds of languages and it differentiate with other systems. It improves quality of a information retrieval system. Distribution and technique transfer of the KRISTAL The efficient information retrieval service of the KISTI and specialized science and technology information center is possible by distribution of the storage engine and management system that can supports multiple languages based on unicode. Also it is possible that improve the productivity of science and technology information and level of information service by development/distribution of distributed- synthesized information retrieval system. And common utilization of information is also possible.
