Self-Organization and Identification of Web Communities

Self-Organization of the Web and Identification of Communities∗

Despite the decentralized and unorganized nature of the web, we show that the web self-organizes such that communities of highly related pages can be efficiently identified based purely on connectivity. This discovery allows the identification of communities independent of, and unbiased by, the specific words used by authors. Applications include improved search engines, content filtering, and ...

Finding Communities in Site Web-Graphs and Citation Graphs

The Web is a typical example of a social network. One of the most intriguing features of the Web is its self-organization behavior, which is usually faced through the existence of communities. The discovery of the communities in a Web-graph can be used to improve the effectiveness of search engines, for purposes of prefetching, bibliographic citation ranking, spam detection, creation of road-ma...

Self-organised virtual communities: bridging the gap between web-based communities and P2P systems

In this paper we argue for the benefits of enabling the self-organization of virtual on-line communities, which today are mainly formed and operated by centrally managed web servers. However, self-organization requires community members to contribute themselves different types of resources (e.g. bandwidth, storage, etc.), as in the case of peer-to-peer (P2P) systems. Unfortunately, this coopera...

Using Reinforcement Learning to Enhance a Knowledge Management System for Web Recommendation Based on Self-Organization of Communities

SWAN: A distributed knowledge infrastructure for Alzheimer disease research

SWAN – a Semantic Web Application in Neuromedicine – is a project to develop an effective, integrated scientific knowledge infrastructure for the Alzheimer Disease (AD) research community, using the energy and self-organization of that community, enabled by Semantic Web technology. This infrastructure may later be deployed for research communities in other neuromedical disorders. SWAN incorpora...
