Organisation du contenu du Web selon la perspective des systèmes complexes adaptatifs

The web continues to grow at a phenomenal rate and the amount of information on the web is overwhelming. Finding the relevant information on the web remains a big challenge. Due to its wide distribution, its openness and high dynamics, the WWW is a complex system, for which we have to imagine mechanisms of content maintaining, filtering and organizing that are able to deal with its evolving dynamics and distribution. This paper explores the web from a complex adaptive system (CAS) perspective. It reviews some characteristic behaviours of CAS and shows how the web exhibits similar behaviours. We illustrate with a model for web content organization adopting the CAS vision and using the multi-agent paradigm. MOTS-CLÉS : organisation du contenu du web, systèmes complexes adaptatifs, autoorganisation, stigmergie.
