Ontology and the Semantic Web

Zhang, Jane January 2007 (has links)
This paper discusses the development of a new information representation system embodied in ontology and the Semantic Web. The new system differs from other representation systems in that it is based on a more sophisticated semantic representation of information, aims to go well beyond the document level, and designed to be understood and processed by machine. A common theme underlying these three features, i.e., turning documents into meaningful interchangeable data, reflects a rising use expectation nurtured by modern technology and, at the same time, presents a unique challenge for its enabling technologies.

Document clustering for electronic meetings: an experimental comparison of two techniques

Roussinov, Dmitri G., Chen, Hsinchun 11 1900 (has links)
Artificial Intelligence Lab, Department of MIS, University of Arizona / In this article, we report our implementation and comparison of two text clustering techniques. One is based on Wardâ s clustering and the other on Kohonenâ s Self-organizing Maps. We have evaluated how closely clusters produced by a computer resemble those created by human experts. We have also measured the time that it takes for an expert to â â clean upâ â the automatically produced clusters. The technique based on Wardâ s clustering was found to be more precise. Both techniques have worked equally well in detecting associations between text documents. We used text messages obtained from group brainstorming meetings.

Search engines are about excitement, optimism, hope and enrichment. Search engines are also about despair and disappointment. A researcher while using search engines for resource discovery might have experienced one or the other sentiments. One may say that user satisfaction depends much upon the search strategies deployed by the user. But at the same time its also depends upon the quality of search engine used for information retrieval. Today, there are many search engines used for resource discovery. They display the results of the searches made in readily-comprehensible manner with lots of customization possibilities including refining and sorting. This paper is an attempt to analyze qualitatively and quantitatively the three most used and popular search engines for academic resource discovery: Google Scholar, Scirus and Windows Live Academic.

A comparative analysis of online peace movement organizations

Hara, Noriko, Shachaf, Pnina January 2008 (has links)
The use of the Internet for civic engagement by the general public is becoming increasingly prevalent, yet research in this area is still sparse. More studies are particularly needed in the area of cross-cultural comparisons of online social movements or online peace movement organizations (PMOs). While it is possible that PMOs in diverse cultures differ in their collective action frames, it is unclear whether PMOs use collective action frames and, if so, how differently they are used. This paper describes a comparative study that examined websites of PMOs in Japan and Israel. Collective action frame is used as a theoretical framework to analyze seventeen websites, identifying the similarities and differences in the ways that online PMOs frame their activities. The findings indicate that these organizations employed various strategies to develop resonance, highlighting the importance of cultural resonance in framing online PMOs in different countries.
