Abstract
In this chapter, besides discussing the current strategies for Web content filtering, outlining their advantages and drawbacks, we present an approach, formerly developed in the framework of the EU project EUFORBIA, which, besides addressing the main drawbacks of the existing systems, can be applied for purposes comprising both users’ protection and quality assurance. The main features of such an approach are the support for multiple metadata vocabularies for the rating and filtering of Web resources, and the possibility of specifying policies which allow the system to decide whether a resource is appropriate or not for a given user based on his/her preferences and characteristics.
