Systems and methods for filtering electronic content according to thesaurus-based contextual analysis of the content are described. The systems and methods of the present invention consist of a list-based and context-based filtering software solution that can be used on personal computers, local area networks, local or remote proxy servers, Internet service providers, or search engines to control access to inappropriate content. Access to content is controlled by a filtering software administrator, who determines which sites and which contexts to restrict.
