Most of the work done in developing Z39.50 was carried out in the basic protocol framework. It becomes apparent that some problems would be quite unacceptable in implementing and reinforcing the networked information retrieval and that it needs some other arrangement such as ISP. This article discussed the current modifications like ISPs by reviewing the unique characters of Z39.50 and the overall design of a client-server search systems, and also distinguished the Z39.50 clients that have been developed as non-profits from those of profits in the perspective of Z39.50 function-expanding.

This study discussed why Precision(& Recall) is not a good effectiveness measurement of IR system providing ranked results, reviewed other effectiveness measurements appropriate for ranked results, and proposed new measurements based on the average rank of relevant documents retrieved. The 18 case-sets of ranked results were used for evaluating 10 effectiveness measurements including proposed measurements. Simple measurements were significantly similar with the 11-Point Precision requiring complicated calculation.

본 논문에서는 내장형 소프트웨어 시스템, 특히 로봇 소프트웨어를 위한 self-managed 소프트웨어 개발 프레임워크로서 SHAGE 프레임워크를 제안하였다. SHAGE 프레임워크는 소프트웨어를 실행시간에 동적으로 변경시킬 수 있도록 지원하는 여러 모듈로 구성되어 있다. Observer가 외부 상황을 관찰하고 관찰된 상황이 Architecture Broker로 전달되면 후보 아키텍처 재구성 전략을 검색하고 Component Broker가 구체화 컴포넌트들을 검색한 후 상황에 적절한 아키텍처 재구성 전략과 컴포넌트 구성을 Decision Maker가 선택한다. Reconfigurator가 선택된 전략과 컴포넌트 구성을 기초로 로봇의 아키텍처를 재구성한다. 적응행위를 Evaluator가 평가하고 그 결과를 Learner가 축적하여 나중에 Decision Maker가 사용할 수 있게 한다. 프레임워크의 효용성을 확인하기 위해서 실제 로봇을 이용한 사례연구를 수행하였고, 이 실험을 통해 적응 과정을 확인하였다. 로봇은 상황과 사용자의 피드백에 적응하였다.

1990년대 중반부터 인터넷의 활성화와 다양하고 강력한 문서편집기의 보편화에 따라 복잡한 문서들이 대량으로 생산됨에 따라 인터넷을 통한 효율적인 문서교환의 필요성이 늘어나고 있다. 그러나 생산된 방대한 양의 전자형태 복합문서들은 ？글, MS-Word, LaTex 등 다양한 문서편집기로 작성되었고 문서형식의 표준화가 이루어지지 않아, 효율적으로 활용되지 못하고 특히 문서교환에 있어 많은 문제점을 야기하고 있는 실정이다. 본 논문에서는 다양한 형태로 존재하는 복합문서들을 하나의 통일된 중간포맷으로 변환하고, 변환된 복합문서들을 전문데이터베이스(full-text database)화하여 이를 인터넷을 통해 효율적으로 검색할 수 있는 전문검색시스템 모델을 제시한다.

XML은 웹2.0 환경에서 데이터의 저장과 전달을 위한 역할을 수행하는 필수적인 포맷으로 각광받고 있다. 특히 RSS나 ATOM과 같은 피드기술은 XML을 이용한 성공적인 사례로 인정받고 있다. 이러한 XML 포맷 데이터는 빠른 검색을 위해 경로기반 클러스터링 기법이나 내용기반 클러스터링 기법을 적용하는 것이 일반적이다. 하지만 클러스터링 기법을 적용할 때 주어지는 임계값에 따라 재현율이 변화하게 되고, 검색 결과에서 배제되는 데이터가 발생하게 된다. 이 논문에서는 기존 클러스터링 기법을 적용할 때 발생하는 데이터 배제현상을 보완하는 2단계 인덱싱 기법을 제안하고, 제안한 방법의 성능에 대해 분석한다.

Lazy loaming methods including CBR have relative advantages in comparison with eager loaming methods such as artificial neural networks and decision trees. However, they are very sensitive to irrelevant features. In other words, when there are irrelevant features, larry learning methods have difficulty in comparing cases. Therefore, their performance can be degraded significantly. To overcome this disadvantage, feature weighting methods for lazy loaming methods have been studied. Most of the existing researches, however, were focused on global feature weighting. In this research, we propose a new local feature weighting method, which we shall call CBDFW. CBDFW stores classification performance of randomly generated feature weight vectors. Then, given a new query case, CBDFW retrieves the successful feature weight vectors and designs a feature weight vector fur the query case. In the test on credit evaluation domain, CBDFW showed better classification accuracy when compared to the results of previous researches.

It can be said that digital technology is at the center of the change in the modern work environment. In particular, in general public institutions that prove their work with records produced by business management systems and document production systems, the record management system is also the work environment itself. Gimpo City applied for the 2021 public cloud leading project of the National Information Society Agency (NIA) to proactively respond to the 4th industrial revolution technology era and implemented a public cloud-based AI-OCR technology enhancement project with 330 million won in support of 330 million won. Through this, it was converted into data beyond the limitations of non-electronic records limited to search and image viewing that depend on standardized index values. In addition, a 98% recognition rate was realized by applying a new technology called AI-OCR. Since digital technology has been used to improve work efficiency, productivity, development cost, and record management service levels of internal and external users, we would like to share the direction of enhancing expertise in the record management and implementation of work environment innovation.

The construction failures can be decreased by continuously improving the construction process based upon the information of construction failures. Herein, the information of construction failures can be utilized as the key factor far identifying the ineffective process and providing the improved construction process that can prevent failures. The objective of this research is to suggest a model for improving construction process continuously by using the information of construction failures. An extended review and analysis of literatures related to the construction failure are performed to investigate the definition, type, cause, and lesson teamed of failure. This research also identifies that process modeling methodology and case-based reasoning are applicable to the construction process improvement, and then it suggests a framework of CIMCP(continuous improvement model of construction process based on the module of case-based reasoning such as case retrieval, case index, and case adaptation.
