Sophisticated techniques from various areas of Artificial Intelligence can be used to improve the access to the WWW; the most promising ones stem from Data Mining and Knowledge Modeling. We describe the process of building two experimental systems: the VSEved system for intelligent meta-search, and the VSEtecka system for navigation support. We discuss our experience from this process, which seems to justify the hypothesis that the Multi-Agent paradigm can improve the efficiency of web access tools, in the future. With this respect, we outline a web-oriented multi-agent architecture.
