Information on the Web includes a huge diversity of opinions, viewpoints, sentiments, emotions, and biases. Accordingly, more and more methods, techniques and tools are available to extract these semantics from text. Representation and exchange of diversity-related information can be easily supported by the use of semantic technologies. For this, we introduce the Knowledge Diversity Ontology (K...

Many works has been made to improve the users browsing on Web sites notably with the adaptation techniques which allow to guide the users according to their profile in order to direct them to the most interesting pages. Considerable improvements has been made in this domain but it is very difficult to judge the impact of the implementation of such techniques on a site. In this paper, we are goi...

Due to the recent growth of the World Wide Web, numerous spatio-temporal applications can obtain their required information from web sources. In this demonstration we show The WorldInfo Assistant, an application that extracts and integrates spatial, temporal and other information about different regions of the world from different web sources and databases. This application also provides integr...

The ability to compare two instances of Internet censorship is important because it is the basis for stating what is or is not justified in terms of, for example, international law or human rights. However these comparisons are challenging, even when comparing two instances of the same kind of censorship within the same country. In this position paper, we use examples of Internet censorship in ...

In this paper we present a model of Web communities which constitute a part of the Web structure. The proposed model is aimed at characterization of the topology behind the Web communities. It is inspired by small world graphs that show behaviors similar to many natural networks. We model Web communities as clusters of Web pages using graph grammars. Graph grammars allow us to simulate the stru...

We describe a system for helping people discover potential collaborators. Similarities between people are found by comparing the items they access on the World-Wide-Web. Using people’s browsing patterns to establish document similarity, we find matches between people without having to analyze the content of the information they access.

One of the main challenges for those working in the field of ICT mediated learning is to develop innovative systems to support the knowledge building process. Did@browser, a system developed in the Institute for Educational Technology, is an attempt to meet this challenge. It is a new educational tool for middle schools which stimulates awareness of students’ cognitive and learning strategies b...
