Since 1991 when the first Web pages wore placed on the internet, information access for numerous Web sites has developed new indexing methods which are different from traditional methods. This paper, as a basic research, deals with Web indexing(Website indexing). Embedded indexing providing basics of Web indexing is examined, and essential META tags used in Web indexing are reviewed in brief. Finally, all the important issues of Web indexing are investigated in detail.

Back-of-book-style indexes have a similar function as back-of-book indexes. The best advantage o4 back-of-book-style indexes for Information access on the web is to give direct access to specific subjects of interest. Though back-of-book-style indexes are alphabetically arranged as back-of-book indexes, they have linked index entries to contents on the site by using a anchor tag of HTML. In this research, I have created back-of-book-style indexes in two separated ways, by hand-crafted and semi-automatic Indexing. We have utilized back-of-book-style indexes, that is similar to back-of-book index of traditional information organization method of library and information science, in library circumstances.

Although traditional printed materials m indexed and abstracted by human beings with tools like thesaurus or controlled vocabulary, information resources on World Wide Web(WWW) are automatically indexed and abstracted without human beings efforts. It would be useful to investigate what major differences are in processes and in elements of indexing and abstracting between traditional printed materials and information resources on WWW. After discussing how WWW search engines work, six major WWW search engines were chosen for this study. Then, 17 indexing elements, 11 abstracting elements, and 2 meta elements were examined. Overall trends and issues for the future development of indexing and abstracting on WWW are also discussed.

논문에서는 최근 인터넷 상에서 표준 공통 포맷으로 대두되는 XML을 이용하여 웹 기반의 역사자료의 데이터베이스 검색 시스템을 설계 및 구현하였다. 원격 교육 시스템의 참조문헌 지원 시스템을 설계하였다. 컴퓨터 상에서 고문헌 자료 주로 한자를 입력하고 검색할 수 있는 환경이 점차 나아지고 있다고는 하지만, 여전히 원전사료의 한자를 일반적인 환경에서 자유롭게 구현하는 일은 결코 용이하지 않다. 종래의 연구자들은 텍스트 별로 수작업으로 작성한 색인류를 이용하여 연구를 해왔다. 그러나 이러한 색인 이용방법에는 문제가 있다. 색인어로 삼고자 하는 단어를 텍스트에서 추출하는 과정에서 누락되는 경우가 있기 때문이다. 전산화된 데이터는 이른바 '발견적 이용'이라는 관점에서 활용될 수 있다.

최근 XML 데이터베이스는 웹의 발전과 더불어 광범위한 인터넷의 자원 공유에 크게 기여하고 있다. XML로 작성된 문서를 저장하고 검색하기 위해 XML 문서의 저장, 질의언어, 질의처리 등에 대한 분야가 활발히 연구되고 있다. 특히 그 중 질의처리의 처리비용을 줄이기 위한 데이터 질의 최적화 기법에 관한 연구가 중요한 과제이다. 증포된 엘리먼트에 대한 기존의 색인기법들은 일차원 색인구조를 이용함으로써 XML Schema가 가지는 타입상속 개념을 고려한 XML 질의들에 대한 처리를 효율적으로 지원하지 못하는 문제점을 가지고 있다. 따라서 본 논문에서는 XML Schema가 가지는 타입상속 개념을 고려한 XML 질의들에 대한 처리를 효율적으로 지원할 수 있는 다차원 증포 엘리먼트 색인구조와 다차원 경로 엘리먼트 색인구조의 운용법을 제시한다. 또한 효과적인 질의 처리를 하기 위한 XML 데이터베이스 색인구조의 유지비용을 줄이기 위하여 저장 공간 및 갱신 유지 비용을 최소화할 수 있는 효과적인 색인할당 방법을 제시한다.

Structures of stories, paragraphs, and sentences and inferences applied to indexing and searching were studied to construct the full-text and sentence retrieval system for storytelling. The system designed the database of stories, paragraphs, and sentences and the knowledge-base of inference rules to aid to write the story. The Knowledge-base comprised the files of story frames, paragraph scripts, and sentence logics made by mark-up languages like SWRL etc. able to operate in semantic web. It is necessary to establish more precise indexing language represented the sentences and to create a mark-up languages able to construct more accurate inference rules.

Over the years, great attention has been paid to the question of exploiting inherent semantic of HTML in the area of web document retrieval. Although HTML is mainly presentation oriented, HTML tags implicitly contain useful semantics that can be catch meaning of text. Focusing on this idea. in this paper we define 'markup pattern' and try to improve performance of web document retrieval using markup patterns. Markup pattern is a mirror of intends of web document publisher and an internal semantic of text on web document. To discover the markup pattern and exploit it, we suggest a new scheme for extracting concepts and weighting documents. For evaluation task, we select two domains-BBC and CNN web sites, and use their search engines to gather domain documents. We re-weight and re-score documents using proposed scheme, and show the performance improvement in the two domains.

The development of the information retrieval field is evolving to the research field searching accurately for the information from thing finding rapidly a large amount of information. Personalization and the semantic web technology is a key technology. The automatic indexing technology about the web document and throughput go beyond the research stage and show up as the practical service. However, there is a lack of research on the document information retrieval field about the attached document type of except the web document. In this paper, we illustrate about the method in which it analyzed the text content of the unstructured documents prepared in the text, word, hwp form and it how to construction OWL ontology. To build TBox of the document ontology and the resources which can be obtained from the document is selected, and we implement with the system in order to utilize as the instant of the constructed document ontology. It is effectually usable in the information retrieval and document management system using the semantic technology of the correspondence document as the ontology automatic construction of this kind of the unstructured documents.

The purpose of this study is to construct a digital archive system by analyzing the collections of the Korean Christian Museum at S University, which has a large number of materials related to Korean Christianity published in the modern period from the time of Korea's enlightenment until liberation. In order to construct a digital archive system, indexes and metadata for the collection are complied according to the pre-defined format. After digitizing the selected collection, a database is built using metadata information, and the actual system is divided into a web standard-based management system and a user service system. Also a content-based search system is constructed, which provides the matching value of retrieval results in units of one character and an automatic search term completion function to enhance user convenience. Therefore, collections in the museum, which are difficult to access the original text, are digitized and provided so that they can be easily used, laying the foundation for the long-term development of humanities contents for improving the accessibility and availability of collections for both researchers and the public.

With the development of semantic web technologies in information retrieval area, the necessity for thesaurus is recently increasing along with internet lexicons. A thesaurus is the combination of classification and a lexicon, and is the topic map of knowledge structure expressing relations among concepts(terms) subject to human knowledge activities such as learning and research using formally organized and controlled index terms for clarifying the context of superordinate and subordinate concepts. However, although thesaurus are regarded as essential tools for controlling and standardizing terms and searching and processing information efficiently, we do not have a Korean thesaurus for geology. To build a thesaurus, we need standardized and well-defined guidelines. The standardized guidelines enable efficient information management and help information users use correct information easily and conveniently. The present study purposed to build a thesaurus system with terms used in geology. For this, First, we surveyed related works for standardizing geological terms in Korea and other countries. Second, we defined geological topics in 15 areas and prepared a classification system(draft) for each topic. Third, based on the geological thesaurus classification system, we created the specification of geological thesaurus. Lastly, we designed and implemented an internet-based geological thesaurus system using the specification.
