A system and method is described herein that uses community-based metadata to improve the manner by which a search engine generates an abstract for a document, such as a Web page. The community-based metadata may comprise, for example, tags or descriptors associated with the document by users of a Web service, such as users of a social bookmarking Web service. By using community-based metadata to help identify text fragments within a document that are most suitable for generating the abstract, an embodiment of the present invention generates an abstract that more accurately represents relevant document content as compared to conventional abstract generation algorithms.
