document: Using annotations in enterprise search A major difference between corporate intranets and the Internet is that in intranets the barrier for users to create web pages is much higher . This limits the amount and quality of anchor text , one of the major factors used by Internet search engines , making intranet search more difficult . The social phenomenon at play also means that spam is relatively rare . Both on the Internet and in intranets , users are often willing to cooperate with the search engine in improving the search experience . These characteristics naturally lead to considering using user feedback to improve search quality in intranets . In this paper we show how a particular form of feedback , namely user annotations , can be used to improve the quality of intranet search . An annotation is a short description of the contents of a web page , which can be considered a substitute for anchor text . We propose two ways to obtain user annotations , using explicit and implicit feedback , and show how they can be integrated into a search engine . Preliminary experiments on the IBM intranet demonstrate that using annotations improves the search quality .
