摘要：A document search and retrieval system and method stores documents ingroups based on content. The documents are self-organized into a hierarchy ofconceptual clusters, and branches of the hierarchy are stored separately in distinct
physical stores, each having an index. In response to a query, the system finds theconcepts (clusters) that best match the search criteria and returns the documents fromthose content categories. The indexing, clustering, and searching are performed usingdocument themes and/or summaries. Themes are automatically developed by stemmingand scoring phrases from the sentences in each document, and clustering the sentencescontaining the highest-scoring stems. A set of phrases (themes) is taken from eachcluster. Document summaries are taken from text segments for each cluster ofsentences within a document, then strung together to create a summary.
