Recently data growth rates are growing exponentially according to the rapid expansion of internet. Since users need some of all the information, they carry a heavy workload for examination and discovery of the necessary contents. Therefore information retrieval must provide hierarchical class information and the priority of examination through the evaluation of similarity on query and documents. In this paper we propose an Multi-class support vector machines model based clustering for hierarchical document categorization that make semantic search possible considering the word co-occurrence measures. A combination of hierarchical document categorization and SVM classifier gives high performance for analytical classification of web documents that increase exponentially according to extension of document hierarchy. More information retrieval systems are expected to use our proposed model in their developments and can perform a accurate and rapid information retrieval service.

Considering that the classified items in the work section level can have an applicability when those items are being used to cost and specification information with consistency, the work section classification code should be applied as an Integrated code system. Our construction industry is using three work section classification systems for civil engineering projects, such as integrated construction information classification system, standard method of measurement and guide of project specification. And each standard construction specification is also using different work section classification systems. This study suggests a methodology to integrate the code systems in construction specifications with civil engineering standard method of measurement. And the methodology suggested in this study was applied to a web-based prototype system with practical specification codes.

With the development of deep learning technology, various research and development are underway to estimate preference rankings through learning, and it is used in various fields such as web search, gene classification, recommendation system, and image search. Approximation algorithms are used to estimate deep learning-based preference ranking, which builds more than k comparison sets on all comparison targets to ensure proper accuracy, and how to build comparison sets affects learning. In this paper, we propose a k-disjoint comparison set generation algorithm and a k-chain comparison set generation algorithm, a novel algorithm for generating paired comparison sets for crowd-sourcing-based deep learning affinity measurements. In particular, the experiment confirmed that the k-chaining algorithm, like the conventional circular generation algorithm, also has a random nature that can support stable preference evaluation while ensuring connectivity between data.

As the information-intensive society in 21c based on the environment of global internet is promoted, the software is getting more large and complex, and the demand for the software is increasing briskly. So, it becomes an important issue in academic and industrial field to activate reuse by developing and exchanging the standardized component. Currently, the information services as a product type of each company are provided in foreign market place for reusing a commercial component, but the components which are serviced in each market place are different, insufficient and unstandardized. That is, construction for Component Data Registry based on ISO 11179, is not accomplished. Hence, the national government has stepped up the plan for sending out public component at 2001. Therefore, the systems as a tool for sharing and exchange of data, have to support the meta-information of standardized component. In this paper, we will propose the C_MDR system: a tool to register and manage the standardized meta-information, based upon ISO 11179, for the commercialized common component. The purpose of this system is to systemically share and exchange the data in chain of acceleration of reusing the component. So, we will show the platform of specification for the component meta-information, then define the meta-information according to this platform, also represent the meta-information using XML for enhancing the interoperability of information with other system. Moreover, we will show that three-layered expression make modeling to be simple and understandable. The implementation of this system is to construct a prototype system of the component meta-information through the internet on www, this system uses ASP as a development language and RDBMS Oracle for PC. Thus, we may expect the standardization of the exchanged component metadata, and be able to apply to the exchanged reuse tool.

하천주변 저지대에 주택이나 공장 등의 시설물 집중과 산지의 개발 및 인구 집중으로 인한 도시화 지역의 증가로 홍수 피해는 더욱 커지고 있다. 특히, 상습침수지구의 주민들은 항상 재해로부터 위험을 느끼고 있으므로 새로운 재해관리체계를 구축하여 이에 대한 확고한 대책이 필요하다. 최근 인터넷 사용의 증가로 많은 사용자들이 웹을 통해 다양한 데이터를 공유하고 있으며, 이러한 추세는 더욱 더 증가할 것이다. 인터넷은 다양한 정보를 네트워크를 통해 사용자에게 실시간으로 제공하고 있으며, 통신기술의 발전, 네트워크 통합화 속에서 그 내용과 방식이 더욱 다양해지고 있다. GIS분야에 있어서도 인터넷 네트워크를 이용하여 분산되어 있는 많은 조직이나 사용자들에게 그 기능과 서비스를 제공하는 추세로 바뀌고 있다. Internet GIS는 원격 지리정보 데이타에 대한 접근, 전송, 분석 및 GIS를 표현하는 수단으로 인터넷을 이용하는 특별한 GIS 도구이다. Internet GIS는 전통적인 GIS 소프트웨어가 가지고 있는 대부분의 기능은 물론 인터넷 및 그와 관련된 WWW 및 FTP 프로토콜의 장점을 가지는 부가적인 기능들을 포함할 수 있다. 이들 부가적인 기능은 원격 데이타 및 응용 프로그램의 교환, 지역 컴퓨터에 GIS 응용 프로그램 없이 GIS 분석 기능을 수행, 인터넷상에서 상호작용하는 지도 및 데이타를 표현하는 기능들을 포함한다. Internet GIS는 객체지향적이고 상호운영적이며, 분산적이라는 주요한 특징을 갖는다. 인터넷에서 각각의 GIS 데이타 및 기능성은 하나의 객체로서 서로 다른 서버에 위치하며 필요시 조합 또는 통합되어 운영된다. Internet GIS를 이용한 상습침수지구 지역정보 제공사이트를 구축하기 위해서는 인터넷으로 서비스 할 수 있는 인터넷용 상습침수지구 GIS기본도를 구축이 필요하다. 인터넷 서비스를 위한 상습침수지구 기본도는 또 다른 형태의 주제도라고 볼 수 있으며, 이를 구축하기 위해서는 자료변환 및 가공이 필요하다. 즉, 각 상습침수지구에 필요한 지형도는 국립지리원에서 제작된 1:5,000 수치지형도가 있으나 이는 자료가 방대하고 상습침수지구에 필요하지 않은 자료들을 많이 포함하고 있으므로 상습침수지구의 데이터를 인터넷을 통해 서비스하기 위해서는 많은 불필요한 레이어의 삭제, 서비스 속도를 고려한 데이터의 일반화작업, 지도의 축소.확대 등 자료제공 방식에 따른 작업 그리고 가시성을 고려한 심볼 및 색채 디자인 등의 작업이 수반되어야 하며, 이들을 고려한 인터넷용 GIS기본도를 신규 제작한다. 상습침수지구와 관련된 각종 GIS데이타와 각 기관이 보유하고 있는 공공정보 가운데 공간정보와 연계되어야 하는 자료를 인터넷 GIS를 이용하여 효율적으로 관리하기 위해서는 단계별 구축전략이 필요하다. 따라서 본 논문에서는 인터넷 GIS를 이용하여 상습침수구역관련 정보를 검색, 처리 및 분석할 수 있는 상습침수 구역 종합정보화 시스템을 구축토록 하였다.
