APPARATUS AND METHOD FOR CONTENT ANNOTATION AND CONDITIONAL ANNOTATION RETRIEVAL IN A SEARCH CONTEXT

摘要

Computer systems and methods incorporate user annotations (metadata) regarding various pages or sites, including annotations by a querying user and by members of a trust network defined for the querying user into search and browsing of a corpus such as the World Wide Web. A trust network is defined for each user, and annotations by any member of the querying user's trust network are made visible to the querying user during search and/or browsing of the corpus if the querying user and trust network members use similar queries to identify documents in the corpus. Users can also limit searches to content annotated by members of their trust networks or by members of a community selected by the user.
