The law affects our daily lives, and hence, constitutes a crucial information resource. However, electronic access to legal information using keyword-based retrieval systems appears to provide users with limited satisfaction. There are many factors behind this inadequacy. First, the discrepancies between formal legal terms and their counterparts in common language are quite large. Second, the situation is further confounded by frequent abbreviations in legal terms. Third, even though there is a constant deluge of legal information, users' needs have evolved to demand more Q and A type searches. All of these factors make the existing retrieval systems inefficient and ineffective. This article suggests an ontology-based system as a means to deal with such difficulties. To that end, a legal retrieval system(experimental system), built on the basis of a newly-constructed law ontology, was tested against a keyword-based legal retrieval system(existing one), yielding data on their relative effectiveness in retrieval and user satisfaction.

As the recognition of the importance of user-oriented services is increasing, there has been a heightened attention for finding aids that could improve the effectiveness of searching. This study tried to draw various facet elements that can be applied to the presidential records retrieval system using presidential records as cases in analyzing various resources, considering the importance of facets in finding aids for the improvement of effectiveness in searching in the future and the importance of presidential records in Korea. In drawing facet elements based on the characteristics of presidential records, the websites of the National Archives (NARA) and Presidential (Prime Ministers') Archives as well as their search options were examined as cases. In addition, the morpheme of each title of presidential records were analyzed, as well as the terms entered by the users of the Presidential Archives Portal of Korea, the terms used in the request for information disclosure toward the Presidential Archives in Korea, the search options of the Presidential Archives Portal, and the elements of the description and metadata standards. The significance of this study lies on suggesting the methodology of developing various facets as main elements in finding aids using the presidential records as cases.

In this paper, we analyzed the relationship between user query keywords that is used to search NDSL and technical terms extracted from NDSL journals. For the analysis, we extracted about 833,000 query keywords from NDSL search logs during nearly 17 months and approximately 41,000,000 technical terms from NDSL, INSPEC, FSTA journals. And we used only the English noun phrase in extracted those and then we did an experiment on analysis of equality, relationship analysis and frequency analysis.

정보검색과정에서 온라인 시소러스는 이용자가 생각하고 있는 개념어를 시스템의 색인어로 보다 정확하게 표현하는 동시에, 관련구조를 통해 탐색의 범위를 확장ㆍ축소할 수 있게 한다. 온라인 시소러스를 충분히 활용하기 위해서는 이용자가 시소러스의 구조에 쉽게 접근하여 계층ㆍ관련구조를 충분히 살피고, 용어 사이를 자유롭게 탐험할 수 있는 장치가 필요하다. 본 연구에서는 기존의 시소러스 표시방법의 장단점 등에 근거하여 정보검색과정에서 이용할 수 있는 시소러스 브라우저를 사전탐색 기능, 시소러스 구조의 표시 기능, 탐색문 형성 기능으로 나누어 설계하였다.

이 연구에서는 현재의 정보검색 환경에서 이용자 친화적인 검색 시스템을 개발하기 위한 한 방안으로 개별문서의 지식구조 브라우징 인터페이스를 제안하였다. 개별문서에 대한 지식구조를 자동 생성하기위해 개별문서에 출현한 용어를 이용하여 용어 클러스터링과 클러스터 대표어 선정 작업을 수행하였고, 이를 대상으로 다차원 축척법을 이용하여 2차원 공간에 개별문서의 지식구조를 표현함으로써 이용자가 개별문서에 대해 보다 용이하게 절근할 수 있는 브라우징 인터페이스를 마련하였다.

The study measured whether two search engines retrieve different Web documents for 6 queries. Two different search engines, Alta Vista in terms of keyword search engines and Yahoo in terms of subject directory engines were measured using as criteria, total number of documents retrieved, total number of relevant documents retrieved, recall and precision ratios. In addition, Alta Vista was suitable for specific and technical terms, while Yahoo was effective for general and plain terms. However, more elaborate research needs to be tested in terms of query characteristics.

The purpose of this study is to propose a hierarchical user interfaces for browsing the knowledge structure of a single document. To generate the hierarchical knowledge structure, hierarchical term clustering and cluster representative term selection were performed with a single thesis in information science field, and the result was applied to design the interfaces which browse a single document hierarchically using multidimensional scaling. The interfaces can be applied to develop the user-friendly information retrieval system.

This is to develop Intelligent Retrieval System which can automatically present early query's category terms(association terms connected with knowledge structure of relevant terminology) through learning function and it changes searching form automatically and runs it with association terms. For the reason, this theoretical study of Intelligent Automatic Indexing System abstracts expert's index term through learning and clustering algorism about automatic classification, text mining(categorization), and document category representation. It also demonstrates a good capacity in the aspects of expense, time, recall ratio, and precision ratio.

Technical documents are important research outputs generated by knowledge and information society. In order to properly use the technical documents properly, it is necessary to utilize advanced information processing techniques, such as summarization and information extraction. In this paper, to extract core information, we automatically extracted the terminologies and their definition based on definitional sentences patterns and the structure of technical documents. Based on this, we proposed the system to build a specialized terminology dictionary. And further we suggested the personalized services so that users can utilize the terminology dictionary in various ways as an knowledge memory. The results of this study will allow users to find up-to-date information faster and easier. In addition, providing a personalized terminology dictionary to users can maximize the value, usability, and retrieval efficiency of the dictionary.
