Welcome to NIRVE

The purpose of NIRVE (NIST Information Retrieval Visualization Engine) is to allow you to visualize and manipulate a set of documents resulting from a query to a search engine. The query is characterized by a set of keywords. NIRVE will let you consolidate these keywords into a smaller set of concepts and then will organize the documents into groups, called clusters, based on the documents' concept profiles. You can inspect individual documents and clusters. You can also suppress viewing of selected documents and clusters so as to concentrate on items of greater interest.

NIRVE is brought to you by the Visualization and Virtual Reality Group of NIST. Send questions to John Cugini.
