Disclosed is a computer-assisted method for generating a summary of or a browsing aid for a document. At an index creation time, information that is relevant to at least one dummy query and is necessary to compile at least one temporary summary for the summary or browsing aid is extracted from a document and cached for later use. The information may be compiled into the summary and saved as such. At a search time, the summary or browsing aid is generated using the information that was cached at index creation time. An apparatus for performing this computer-assisted method is also disclosed.

Method and apparatus for rapidly producing document summaries and document browsing aids

A computer method for preparing a summary string from a source document of encoded text. The method comprises comparing a training set of encoded text documents with manually generated summary strings associated therewith to learn probabilities that a given summary word or phrase will appear in summary strings given a source word or phrase appears in encoded text documents and constructing from the source document a summary string containing summary words or phrases having the highest probabilities of appearing in a summary string based on the learned probabilities established in the previous step.
