A Study on Semi-structured Data Extraction for Efficient Data Retrieval

월드와이드웹이 엄청난 정보자원이라는 것은 잘 알려져 있다. 따라서 웹상의 정보를 효과적으로 이용하는 것은 매우 중요하다. 본 고는 웹 페이지로부터 유용한 정보를 추출하기 위해 반구조적인 데이터를 전자문서의 표준인 XML문서로 추출하고 다시 객체관계형 DBMS에 저장함으로써 효과적으로 검색할 수 있다.It is well known that World Wide Web has become a huge information resource. Therefore, it is very important for us to utilize this kind of information effectively. This paper proposes a semi-structured data extraction method to get the useful information from web pages, and store it with XML which de facto standard electronic documents, and then store XML documents to ORDBMS(Object Relational Database Mangement System) for efficiently store and retrieve web-based information resources on the web.ope

The Design and Implementation of an Internet Marketing Analysis System for Electronic Commerce

인터넷의 급속한 성장과 더불어 전자 상거래의 규모가 커져가고 있다.사이버마켓에서 비지니스를 하려는 기업의 입장에서는 고객의 행태가 달라졌으므로 새로운 마케팅 패러다임의 도입이 불가피하다. 고객별로 개별화된 마케팅, 즉 1 대 1 마케팅(one-to-one marketing)이, 그 중 한 가지이다. 이것은 사이버마켓이라는 새로운 환경의 장점을 살리면서 기업의 경쟁력을 극대화할 수 있는 마케팅 방법으로 간주되고 있다. 이에 본 논문에서는 쇼핑몰 운영을 통해 축적된 데이터를 데이터 웨어하우스로 구축한 뒤, ROLAP도구를 통해서 1 대 1 마케팅에 필요한 정보를 분석해내고자 하였다. 이와 더불어, 고객의 특성을 정확히 파악하여 그들의 요구와 흥미에 부합하는 개인화된 정보나 상품, 그리고 서비스를 제공할 수 있는 인터넷 마케팅 분석 시스템 구현 모델을 제시하고자 한다.The scale of electronic commerce is getting larger with the rapid development of the Internet. As the behavior of customers in the cybermarket is different from the one that is in the conventional market, it is necessary for companies to adopt a new marketing paradigm. The individually customized marketing - one-to -one marketing- is known as the way to maximize the core competence of the companies which are to take advantage of the new market environment - the cybermarket. In this paper, the followings are introduced : (1) building a data warehouse of the accumulated data from a cyber shopping mall in use, (2) the analysis of this using a ROLAP tool, and (3) the implementation model of an Internet marketing analysis system to provide the customer-specific individualized marketing information about customers' informational need, products, and services corresponding to their demand and interest.The scale of electronic commerce is getting larger with the rapid development of the Internet.

The Design and Implementation of a Knowledge Management System

기업의 지적자산을 직접적인 경영 대상으로 보는 새로운 인식이, 최근 지식경영이라는 이름으로 확산되고 있다. 이에 본 논문에서는, 실제 중소기업에서 지식관리와 재사용에 활용할 정보시스템의 설계 및 구축을 시도하였다. 구체적으로는, 지식관리 시스템 개발시 고려해야 할 사항, 개발방향 설정, 그리고 개발 방법론 등을 검토하였다. 이를 토대로 지식관리 시스템의 원형을 구현하였다.There is growing recognition by the name of knowlege management that tintellectual assets are the management objects that should be directly managed. In this paper, we try to design and implement an information system for knowledge management and reuse in small-to-medium-sized enterprises. In doing this, we study initial considerations, development directions ans methodology for knowledge management systems. Based on the study, a prototype of the knowledge management system is constructed and described here.There is growing recognition by the name of knowlege management that tintellectual assets are the management objects that should be directly managed.
