UsersÕ information needs are often too complex to be effectively expressed in standard query interfaces to full-text retrieval systems.A typical need is to find documents that are similar to a given source document, yet describing the content of a document in a few terms is a difficult task.We describe Phrasier, an interactive system for browsing, querying and relating documents within a digital library.Phrasier exploits keyphrases that have been automatically extracted from source documents to create links to similar documents and to suggest appropriate query phrases to users.PhrasierÕs keyphrase-based retrieval engine returns ranked lists of documents that are similar to a given source text.Evaluation indicates that PhrasierÕs keyphrase-based retrieval performs as well as full-text retrieval when recall and relevance scores assigned by human assessors are considered.
