Web service technologies provide a standard means for interoperation and integration of heterogeneous applications distributed over the Internet. For efficient execution of hierarchically interacting composite web services, this paper proposes an approach to distribute web service invocations over peer systems effectively, exploiting intensional XML data embedding external service calls as a result of well services. A cost-based optimization problem on the execution of web services using intensional results was formalized, and a heuristic search method to find an optimal solution and a greedy algorithm to generate an efficient invocation plan quickly were suggested in this paper. Experimental evaluation shows that the proposed greedy algorithm provides near-optimal solutions in an acceptable time even for a large number of Web services.

최근에 지리 정보를 검색, 관리, 분석 할 수 있는 지리 정보 시스템(Geographic Information System, CIS)의 사용이 확대됨에 따라 단순한 수치지도 정보 이외에 좀 더 현실적이고, 사실적인 정보를 제공해 줄 수 있는 시스템에 대한 요구가 커지고 있으며 이동통신 기술의 발달과 모바일 단말의 급속한 확산으로 인하여 지리 정보 시스템의 모바일 시스템화가 급속히 진행중이다. 이러한 현상에 맞추어 무선 인터넷 환경에서 공간 객체의 실제 영상 정보를 보여주는 시스템의 필요성이 대두되고 있다. 현장에서 공간 객체에 대한 영상 정보를 검색 할 수 있는 시스템은 현실적 모습 및 상태에 대한 정보를 실시간으로 제공해 줄 수 있어. 공간 객체의 실제 모습이 필요한 여러 분석이나 의사결정이 필요한 분야에서 효율적으로 이용될 수 있다. 공간 객체의 실제 영상 정보를 제공하기 위해 현재 영상을 고려하는 지리 정보 시스템이 개발 중이기는 하나, 이러한 시스템들은 무선 인터넷 환경을 고려하지 않고 있어, 현장에서 공간 객체에 대한 영상을 효율적으로 얻기에는 적합하지 않다. 본 논문에서는 무선 인터넷 환경에서의 공간 객체에 대한 영상 정보 검색 시스템을 설계하고 구현한다. 이를 위 해 1) 수치 지도 및 영상, 그리고 그 매핑 정보의 구축 방안을 제시한다. 그리고, 2) 제안된 시스템을 전체적으로 설계 및 구현함으로써, 그 유용성을 보인다.

In this study, we investigated how to distinguish customer delivered value to re-purchasing in fierce B2C industry. To identify key managerial variables that could distinctively impact re-purchasing, we first identified customer value proposition as per the customer buying decision process. Next, core value propositions of choice efficiency and competitive price are defined to determine vendor satisfaction during the searching stage and purchasing stage. The trust level is also introduced in the sense of reflecting confirmation to guarantee after purchase security. Then, significant managerial variables to impact on core value propositions are extracted. The resulting structural model illustrated that search convenience and quality assurance affect the choice efficiency, and re-purchase intention is strongly explained by both the vendor satisfaction and trust level. The empirical testing results also support that transaction cost reduction is key determinant of shopping at the Internet shopping mall. Furthermore, trust level should be combined to induce re-purchasing in addition to transaction cost savings.

There are currently about 6000 bacterial species with validly published names, but scientists assume that these may be less than 1% of bacterial species present on the earth. Microbial resource is one of the most important bioresources in bioinderstry and provides us with high economic values. To find missing ones, the studies of metagenome, metabolome, and proteome about microbes have started recently in developed countries. We construct the information system that integrates information on microbial genome resources and manages the information to support efficient research of microbial genome application, and name this system 'Bio-Meta Information System (Bio-MIS)'. Bio-MIS consists of integrated microbial genome resources database, microbial genome resources input system, integrated microbial genome resources search engine, microbial resources on-line distribution system, portal service and management via internet. In the future, we will include public database connection and implement useful bioinformatics software for analyzing microbial genome resources.

For analyzing a huge amount of web pages available in the Internet, we need to extract the encoded information in web pages. In this paper, we propose a method to extract and convert web information from web pages into XML documents for multidimensional analysis. For extracting information from web pages, we propose two languages: one for describing web information extraction rules based on the object-oriented model, and another for describing regular expressions of HTML tag patterns to search for target information. For multidimensional analysis on XML documents, we propose a method for constructing an XML warehouse and various XML cubes from it like the way we do for relational data. Finally, we show the validness of our method through the application to US patent web pages.

With the development of the Internet and the increase of smart phones, various services considering user convenience are increasing, so that users can check news in real time anytime and anywhere. However, online news is categorized by media and category, and it provides only a few related search terms, making it difficult to find related news related to keywords. In order to solve this problem, we propose a method to recommend related documents more accurately by applying Doc2Vec similarity to the specific keywords of news articles and weighting the title and contents of news articles. We collect news articles from Naver politics category by web crawling in Java environment, preprocess them, extract topics using LDA modeling, and find similarities using Doc2Vec. To supplement Doc2Vec, we apply TF-IDF to obtain TC(Title Contents) weights for the title and contents of news articles. Then we combine Doc2Vec similarity and TC weight to generate TC weight-similarity and evaluate the similarity between words using PMI technique to confirm the keyword association.

Theses days, a number of data over the Internet are represented using XML because of a virtue of XML. In proportion to the increase of XML data, query processing techniques are required that support quickly and efficiently the diverse queries to search the useful information on XML documents. But, up to now, the researches handling queries for XML data are methodologies focusing on how to process regular path expressions. Therefore, we have developed a new genealogy-based indexing technique to solve various queries such as not only regular path expression but also simple path expression, path expression referencing other elements, and so on. Also, we have applied this technique on object-relational model and evaluated the performance for many documents and various query types. The result shows improved performance in comparison with the other storage techniques.
