WWW which is an applicable massive set of document on the Web is a thesaurus of various information for users. However, Search engines spend a lot of time to retrieve necessary information and to filter out unnecessary information for user. In this paper, we propose the EFAM(the Extended Fuzzy AHP Method) model to manage the Web resource efficiently, and to make a decision in the problem of specific domain definitely. The EFAM model is concerned with the emotion analysis based on the domain corpus information, and it composed with systematic common concept grids by the knowledge of multiple experts. Therefore, The proposed the EFAM model can extract the documents by considering on the emotion criteria in the semantic context that is extracted concept from the corpus of specific domain and confirms that our model provides more efficient decision-making through an experiment than the conventional methods such as AHP and Fuzzy AHP which describe as a hierarchical structure elements about decision-making based on the alternatives, evaluation criteria, subjective attribute weight and fuzzy relation between concept and object.

The importance of early project planning is broadly recognized for construction projects. From the planning step, If extensive historical data related with the project is applied effectively, It can be major resource for estimating cost and project scope. However, The accumulation, analysis, and application of historical data is not sufficient in Korea. So useful information of construction project has disappeared. In order to solve the problems, Project Historical Data Management Systems is need to be developed. The purpose of this study is to analyze current problems and to find the method to utilize historical data in similar project.

EMF (Electromagnetic Field) is a valuable resource for living in a knowledge-based information society. The EMF is used in home appliances that make our lives easy and convenient, and in telecommunication devices such as mobile phones, personal computers, medical devices and broadcasting towers. However, the biological hazards associated with EMF exposure are also increasing in signal from telecommunication devices. Studies of the effects of EMF exposure on humans have been conducted for a long time, but it has not yet been demonstrated whether the EMF effect is harmful. In this paper, we examine the electromagnetic field emitted from various electronic devices around living and its effect.

RDF is widely used as the ontology language for representing metadata on the semantic web. Since ontology models the real-world, ontology changes overtime. Thus, it is very important to detect and analyze changes in knowledge base system. Earlier studies on detecting changes between RDF models focused on the structural differences. Some techniques which reduce the size of the delta by considering the RDFS entailment rules have been introduced. However, inferencing with RDF models increases data size and upload time. In this paper, we propose a new change detection using RDF reasoning that only computes a small part of the implied triples using backward chaining strategy. We show that our approach efficiently detects changes through experiments with real-life RDF datasets.

Conventional exhibition management information systems recommend tourist attractions that are close to the place in which an exhibition is held. Some recommended attractions by the location-based recommendation could be meaningless when nothing is related to the exhibition's topic. Our goal is to recommend attractions that are related to the content presented in the exhibition, which can be coined as content-based recommendation. Even though human exhibition curators can do this, the quality is limited to their manual task and knowledge. We propose an automatic way of discovering attractions relevant to an exhibition of interests. Language resources are incorporated to discover attractions that are more meaningful. Because a typical single machine is unable to deal with such large-scale language resources efficiently, we implemented the algorithm on top of Apache Spark, which is a well-known distributed computing framework. As a user interface prototype, a web-based system is implemented that provides users with a list of relevant attractions when users are browsing exhibition information, available at http://bike.snu.ac.kr/WARP. We carried out a case study based on Korean Tourism Organization Linked Open Data with Korean Wikipedia as a language resource. Experimental results are demonstrated to show the efficiency and effectiveness of the proposed system. The effectiveness was evaluated against well-known exhibitions. It is expected that the proposed approach will contribute to the development of both exhibition and tourist industries by motivating exhibition visitors to become active tourists.

Library 2.0 advocates a socially rich, multimedia enabled, user originated and communally innovative environment that poses significant opportunities for the libraries to evolve and make themselves even more relevant and significant for her users. This paper presents a case study of the National Library Board of Singapore, in playing a vital role to facilitate the realisation of a long-term key national program, The Singapore Memory (SM) Project. SM embraces the attributes of the Library 2.0 environment to enable the nation's memory to be collected, organised, preserved, discovered, researched, augmented and created. The output of is an evolving collection of knowledge assets on Singapore along a Singapore Memory Content Continuum of existing content that is steadily augmented with new content. The content will be collected across all formats, in any language, from Singaporeans and non-Singaporeans, from any institution and agency, from Singapore and abroad, and from official and unofficial sources. The utopian scenario of SM Project is that any person, community, group or institution who has ever experienced Singapore in any way or has any material on Singapore will engage actively in the contribution, discovery and creation of content for the project, and thus become advocates to further encourage and catalyse more contribution, discovery and creation. The paper outlines the key approaches, concepts and ideas for the project. An important element is the proliferation, exposure and accessibility of the rich contents envisaged in the project. The SM proliferation plan along with examples of how two existing resources, namely, the Singapore Infopedia, a database of articles on Singapore's history, culture, people and events 4 and NewspaperSG, an online resource of current and historic Singapore and Malayan newspapers, have been designed are presented to demonstrate how content can be exposed, searched and discovered.

The publication of the result of scholarly research is an integral part of the process by which learning is advanced. The university presses, as one of the major scholarly publishers are now confronted with many critical problems, such as the declining unit sales, the explosion of manuscripts, the challenge of new publishing technologies, etc., in performing the role of the scholarly communication system. The purpose of this study is to identify the problems imposed on the university presses and alternative strategies for them. For the study, the related literature to the subject were read, analyzed and synthesized, from which the overall prospect of the problems and alternative strategies are derived. The conclusion of the study can be summarized as follows: (1) The faith of the university should lie in its role to advance scholarly learning through production and dissemination of high-quality knowledge, and the university press should materialize such a faith. (2) The scholarly books, though not the best media of scholarly communication taking a side view of its timeliness and brevity, can perform the function of the best media for the specific subject and readers. (3) The scholarly books as national resource must be published for the scholars demanding them even though the publication can't help depending on the subsidiary fund. (4) For the survival and activation of the university presses, the following strategies should be examined, and put in force if necessary. (a) The role of the foundation su n.0, pporting the university presses should be expanded (b) The Co-operative system among the operations of the presses should be established. (c) It is desirable that the university without the press should participate in the university with the press for both the financial su n.0, pporting and the publicizing its faculty's manuscripts. (d) The positive efforts should be made for the increase of sales copies by implementing the dual-system of publication. (e) It is desirable that 'recording system' should be incorporated in the traditional publication system both for the lightening of financial problems and the explosion of publications. (f) It is necessary that the effective methods of the bibliographical control should be developed for the improvement of the scholarly communication. (g) Any kind of the permanent organization composed of the representatives from all the infrastructures of information industry should be established to study the character and direction of technological changes and to discern the better choice of specific, technologies in the scholarly communication system.

Ontology is an indispensable component in intelligent and semantic processing of knowledge and information, such as in semantic web. Ontology is considered to be constructed generally on the basis of taxonomy of human concepts about the world. However. as human concepts are unstructured and obscure, ontology construction based on the taxonomy of human concepts cannot be realized systematically furthermore automatically. So, we try to do this from the relation among linguistic symbols regarded representing human concepts, in short, words. We show the similarity between taxonomy of human concepts and relation among words. And we propose a methodology to construct and generate automatically ontologies from these relations mon words and a series of algorithm to convert these relations into ontologies. This paper presents the process and concrete application of this methodology.

This study aims for developing an instructional design strategy to improve collaborative teaching between teacher librarians and subject teachers in library-assisted instruction. Collaborative teaching is an important management activity enhancing teaching role of teacher librarians in their school community. But in the actual condition the level of the library-assisted instruction as its practical strategy is cooperation and subject teachers are leading teaching and learning except for selecting resources. Because library-assisted instruction is resource-based learning, the procedural knowledge of information literacy curricula and topics of subject specific curricula should be designed as a whole. Also, there must be possibilities of reducing trial and error and expanding successes. From these sides, the collaborative design strategy for library-assisted instruction can be planned like 'statement of learning situation-co designing-co teaching-co evaluating'.
