Evaluation of Full-Text Retrieval System Using Collection of Serially Evolved Documents

Finding a document that is similar to a specified query document within a large document database is one of important issues in the Big Data era, as most data available is in the form of unstructured texts. Our testing collection consists of two parts: In the first part texts were produced by human work by artificial plagiarism approach through the linear pipelined procedure. In the second part, texts are generated by software that inserts, deletes, and substitutes certain parts of the target documents to make a similar document from an input document. These document set is known as the Serially Evolved Documents (SED). We propose new methods: Order Preserving Precision (OPP) and Order Preserving Recall (OPR), to compute how the evolutionary order is kept among output documents obtained from the subject IR system. Using those testing texts we evaluated KONAN, a document retrieval system for Korean documents.

A Case Study on International Technology Transfer of Korean Public Information Systems and Recommendations for NTIS

국제기술이전은 이해관계 불일치, 기술수준, 문화 등 여러 거시적 환경여건의 차이로 국내기술이전보다 더 어려운 점이 많은 것으로 알려져 있다. 본 연구에서는 정보마케팅의 관점에서 국내 공공정보시스템의 국제기술이전 사례연구를 통해 미래창조과학부 NTIS의 해외진출에 관해 제언하고자 한다. 국내 공공정보시스템 국제기술이전의 대표적 성공사례로 평가되는 관세청, 특허청, 조달청의 국제기술이전을 성공시키기까지의 과정을 분석하여 국가과학기술지식정보서비스(NTIS)의 국제기술이전 촉진을 위한 정보마케팅 관점에서 사전준비전략을 제시한다.

Design and Implementation Issues for Expanding Information in a Service (NTIS)

National Science & Technology Information Service(NTIS) established a system that collect, manage and service the information of national Research and Development(R&D) program in Korea. However, the existing system can’t support monitoring of detailed fund usage results of projects and commissioned projects. To solve this problem, NTIS need to collect additional detail information including each expense items of projects, co-work projects, commissioned projects and co-research information. We designed NTIS database structure for the improvement project and implemented the registration and management functions at the Standard Information Management Service(SIMS).
