Fuzzy approaches to access information on the web: recent developments and research trends

In this paper some research trends are presented concerning the application of fuzzy techniques to model flexible systems for the access to information on the WWW. The focus is on the definition of flexible systems, i.e. systems that can represent and manage the vagueness and uncertainty which is characteristic of the process of information searching and retrieval. We also identify some research directions which are worth to explore by the fuzzy community.
