  • This study identifies the concept of a digital convergence paradigm, which deals with the relationship among convergence and consumer participation, digital contents services, and the culture of consumption (web 2.0). This research was conducted using a quantitative method involving focus group interviews (FGI) and literature reviews. This research examines the relationship between convergence and consumer participation and the adoption of a concept of "convergence culture", which is categorized as "collective intelligence" and "intellectual community participation". The role of the consumer has changed from one of a "consuming consumer" to that of a "collaborating consumer" and finally to the concept of a consumers as the originator of a new consumption culture. In the study, the consumption culture of web participants indicated the characteristics of funology, self-expression, life-catching, quick-tempered, immersion(arousal), sharing culture, multitasking, and cyber justice. The recognition level of networking on the "digital convergence" of the consumer was identified as that of the combination of IT(information technology); product and multi-services or alliance of industry groups(telecom, broadband, IPTV service); or the use of one source with multiple devices.

  • As web technologies evolve and so-called Web 2.0 technologies appear, collective intelligence is being applied in widespread areas. In general, mass collective intelligence like Wikipedia is created, revised, and managed by anonymous participants in an uncontrolled system. Thus, the knowledge provided by mass collective intelligence may be distorted, and may not be true, which may affect the user acceptance behavior. However, there have been few academic studies that analyzed the factors that affect user acceptance of mass collective intelligence, and their relationships. Under this academic background, we develop a model to examine how mass collective intelligence is accepted by users. The theoretical model is validated through an online survey of the Wikipedia users from three universities in Korea. The results reveal that the users will have positive attitude towards adopting mass collective knowledge when they perceive that the knowledge from mass collective intelligence is useful. We also find that the perceived usefulness of the knowledge is affected by perceived knowledge quality and trust in knowledge contributors. The results also suggest that perceived knowledge quality is determined by perceived level of collaboration, perceived objectivity, and recipient expertise, whereas trust in knowledge contributors is determined by natural propensity to trust and perceived objectivity. Theoretical and practical implications about mass collective knowledge are discussed.

  • The new technology, RSS(Really Simple Syndication), allows people to send and receive a lot of up-to-date information by constant monitoring websites and databases for new information, without having to visit the site or database. The "gatekeeping" task for capturing and delivering various information influx via new digital channels as speedy as possible, is being discussed as a new form of service in the field of information service system nowadays. Given this situation, the RSS tool can be greatly useful in the gatekeeping task. This paper, by analyzing concrete cases in which RSS is actually employed in libraries and also newly applied to other diverse information services in France, expects to provide insightful ideas for developing innovative information services in other countries.

  • Recently, the various web service and applications are provided to the user. As to these service, because of providing the service to the authenticated user, the user undergoes the inconvenience of performing the authentication with the service especially every time. The OAuth(Open Authorization) protocol which acquires the access privilege in which 3rd Party application is limited on the web service in order to resolve this inconvenience appeared. This OAuth protocol provides the service which is convenient and flexible to the user but has the security vulnerability about the authorization acquisition. Therefore, we propose the method that analyze the security vulnerability which it can be generated in the OAuth 2.0 protocol and secure user authority authentication method.

  • Information retrieval is the challenge of the Web 2.0 world. The experiment of knowledge organisation in the context of abundant information available from various sources proves a major hurdle in obtaining information retrieval with greater precision and recall. The fast-changing landscape of information organisation through social networking sites at a personal level creates a world of opportunities for data scientists and also library professionals to assimilate the social data with expert created data. Thus, folksonomies or social tags play a vital role in information organisation and retrieval. The comparison of these user-created tags with expert-created index terms, author keywords and title words, will throw light on the differentiation between these sets of data. Such comparative studies show revelation of a new set of terms to enhance subject access and reflect the extent of similarity between user-generated tags and other set of terms. The CiteULike tags extracted from 5,150 scholarly journal articles in marine science were compared with corresponding Aquatic Science and Fisheries Abstracts descriptors, author keywords, and title terms. The Jaccard similarity coefficient method was employed to compare the social tags with the above mentioned wordsets, and results proved the presence of user-generated keywords in Aquatic Science and Fisheries Abstracts descriptors, author keywords, and title words. While using information retrieval techniques like stemmer and lemmatization, the results were found to enhance keywords to subject access.

  • Background: Nodal invasion by colorectal cancer is a critical determinant in estimating patient survival and in choosing appropriate preoperative treatment. The present meta-analysis was designed to evaluate the diagnostic value of endorectal ultrasound (EUS) in preoperative assessment of lymph node involvement in colorectal cancer. Materials and Methods: We systematically searched PubMed, Web of Science, Embase, and China National Knowledge Infrastructure (CNKI) databases for relevant studies published on or before December 10th, 2014. The sensitivity, specificity, likelihood ratios, diagnostic odds ratio (DOR) and area under the summary receiver operating characteristics curve (AUC) were assessed to estimate the diagnostic value of EUS. Subgroup analysis and meta-regression were performed to explore heterogeneity across studies. Results: Thirty-three studies covering 3,016 subjects were included. The pooled sensitivity and specificity were 0.69 (95%CI: 0.63-0.75) and 0.77 (95%CI: 0.73-0.82), respectively. The positive and negative likelihood ratios were 3.09 (95%CI: 2.52-3.78) and 0.39 (95%CI: 0.32-0.48), respectively. The DOR was 7.84 (95%CI: 5.56-11.08), and AUC was 0.80 (95%CI: 0.77-0.84). Conclusions: This meta-analysis indicated that EUS has moderate diagnostic value in preoperative assessment of lymph node involvement in colorectal cancer. Further refinements in technology and diagnostic criteria are necessary to improve the diagnostic accuracy of EUS.

  • The change in information technology demands drastic change in digital library service. This study defines what a social semantic digital library should consist of and proposes a new architecture that incorporates core functions needed in designing a SSDL. The SSDL supports semantic information processing based on metadata and ontology and is an innovation system that allows SSDL users to participate in generating new knowledge by interacting with existing metadata and ontology structures. This study designed a SSDL model that consists of five horizontal and two vertical structures.
