This paper introduced Internet totally, which is continuously changing, for the aspect of service-improvement to users. Particulary, the concepts, the features and methods of Gopher, Veronica, Archie, WAIS and WWW which are used broadly in the aspect of information retrieval, have been introduced with command-language in Internet. Among them, this paper intends not only to describe in detail the use of Web-browser's method but also to explain about the search engine which is provided in the large online service on the base of actual experience.

The purpose of the present study is to verify the two hypotheses: (1) Online services are fundamentally automated versions of the reference services. Accordingly there will be a major impact on reference services when Online service is introduced into the traditional library environment. The chief impact will be that the use of data bases retrieval service supplements and improves the traditional reference service when Online service is coordinated with the traditional reference service. and is fully incorporated into the existing user service areas. (2) The availability of data bases retrieval service will make it possible for the first time for the reference services to offer substantial search services of any kind resources limited to the printed sources. In light of such circumstances, libraries would provide better service to their users and greatly increase the productivity of reference librarians. There will be also the recognition that a result of an improved professional image for reference librarians and the library heightens user interest. This change may be translated into increased usage of library services generally. To achieve the purpose, 4 Research Libraries adopted Online retrieval from DIALOG's data bases-searching and reference services available in-house were chosen.

The unstructured and semi-structured big data in social network poses new challenges in query retrieval. This requirement needs to be met by introducing quality retrieval time measures like indexing. Due to the huge volume of data storage, there originate the need for efficient index algorithms to promote query processing. However, conventional algorithms fail to index the huge amount of frequently obtained information in real time and fall short of providing scalable indexing service. In this paper, a new LIndex algorithm, which is a heuristic on Lucene is built on Neo4jHA architecture that holds the social network Big data. LIndex is a flexible and simplified adaptive indexing scheme that ascendancy decomposed shortest paths around term neighbors as basic indexing unit. This newfangled index proves to be effectual in query space pruning of graph database Neo4j, scalable in index construction and deployment. A graph query is processed and optimized beyond the traditional Lucene in a time-based manner to a more efficient path method in LIndex. This advanced algorithm significantly reduces query fetch without compromising the quality of results in time. The experiments are conducted to confirm the efficiency of the proposed query retrieval in Neo4j graph NoSQL database.

Recently the mobile RFID technique research is applied in the portion which is various with fusion of RFID technique and the mobile machine of communication alcoholic beverage of existing. As result of this research, the establishment of the new mobile RFID code system and research and development of retrieval system are advanced. Like this the retrieval system where researching and developing are advanced is appropriate in each application field and it is not applied there is a problem point. So the mobile RFID retrieval system which uses the product from the dissertation which it sees newly the area. It is a Lospector that it proposes and the retrieval system is appropriate in each service field and it is not applied to improve the problem point, it presents an efficient search technique.

Web based simulation service is utilized to computationally analyze various phenomena in real world according to the progress of network and computing technology. To provide suitable simulation service, web based simulation service will be improved by analyzing execution data. Especially, an API for data retrieval is designed, because every analyst needs different data. In this paper, we design the retrieval API for a user to analyze the web based simulation execution data, which is used on CFD (Cumputational Fluid Dynamics) and Chemistry. The designed retrieval API provides an simulation execution data depending on an user requirement such as a user type, an execution period, and an affiliation, which is based on the core information such as an user, a simulation program, and a cyberlab. Besides, a developer can provides a suitable information for a user to execute a simulation well such as a simulation statistics, an execution trend, and a frequent error.

This study is to design a Semantic Navigation Retrieval System for Oriental Medicine Articles based on a XTM so that people can search and use them more effectively than before. Keywords extracted from articles are categorized 4 topics : herbs, prescription, disease, and action. Keywords analysis Ontology is modeled based on 4 topics and their relations, and then represented Topic maps. Next, Article analysis Ontology is consist of title, author, keywords, abstracts and organization Topics from metadata. Keywords and Article analysis Ontology were integrated through Keywords Topic. Korean Medical Article Retrieval System is optimistic in terms on search results supporting semantic navigation in the information service aspects and easier accessibility because all related information are semantically connected with each different DBs.

In current Web 2.0 environment, one of the most core technology is social bookmarking which users put tags and bookmarks to their interesting Web pages. The main purpose of social bookmarking is an effective information service by use of retrieval, grouping and share based on user's bookmark information and tagging result of their interesting Web pages. But, current social bookmarking system uses the number of bookmarks and tag information separately in information retrieval, where the number of bookmarks stand for user's degree of interest on Web contents, information retrieval, and classification serve the purpose of tag information. Because of above reason, social bookmarking system does not utilize effectively the bookmark information and tagging result. This paper proposes a Web contents ranking algorithm combining bookmarks and tag information, based on preceding research on associative tag extraction by tag clustering. Moreover, we conduct a performance evaluation comparing with existing retrieval methodology for efficiency analysis of our proposed algorithm. As the result, social bookmarking system utilizing bookmark with tag, key point of our research, deduces a effective retrieval results compare with existing systems.

In these days everyone search the information easily with the Internet as the rapid distribution and active usage of the Internet. The search engines were developed specially to accuracy of information retrieval. User search the information more quickly and variously with them. The search portal system will be embossed with representation and basic services. The Internet user needs the result of text, image and video, knowledge search. The keyword based search is used generally for getting result of the information retrieval and another method is category based search. This paper investigates the classification of knowledge search structure for oriental medicine in market leader of search portal system by ranking web site. As a result, each classification system is unified and there is a possibility of getting up a many confusion to the user who approaches with classification systematic search method. This treatise proposed the improved oriental medicine classification system of internet information retrieval in knowledge search area. if the service provider amends about the classification system, there will be able to guarantee the compatibility of data. Also the proper access path of the knowledge which seeks is secured to user.
