Actual document search engines base searches on the file name or syntactic content, which means that the word or part of the word to search must exactly match. This article proposes a semantic graph-based method for document search. The approach allows to organize, search, and display documents or groups of documents. Groups are formed according to topics contained in documents.

Organizing multimedia data is very challenging. One of the most important approaches to support users in searching and navigating media collections is collaborative filtering. Recently, systems as flickr or last.fm have become popular. They allow users to not only rate but also tag items with arbitrary labels. Such systems replace the concept of a global common ontology, as envisioned by the Se...

This paper is concerned with a case study in content-based classification of textual documents. In particular we compare the application of two prominent self-organizing neural networks to the same problem domain, namely the organization of software libraries. The two models are Adaptive Resonance Theory and Self-Organizing Maps. As a result we are able to show that both models successfully arr...

Many grid architectures have been developed since the first protogrid systems in the early 70’s, but there are not so many based on groups using an efficient node neighbor selection. This paper proposes a grid architecture based on groups. The architecture organizes logical connections between nodes from different groups of nodes allowing sharing resources, data or computing time between groups...

This paper presents generic simulation tools which rely on an original methodological approach of designing multi-agent simulators. We will see that these tools are generic specially because they are not related to a particular scheduling method. On the contrary they aim at providing facilities that allow to design complex activation structures that remain comprehensible, analyzable and moreove...
