AI Technical Summary

Benefits of technology

The system effectively generates summaries by selecting the appropriate summarization engine for each document cluster, optimizing the summarization process for various document types, thereby enabling users to quickly and efficiently browse large quantities of content.

Problems solved by technology

While the performance of the MultiGen system is suitable for use with documents which are closely related, this system was not intended to generate summaries for document collections which axe less closely related, such as collections of documents addressing multiple events, issues and biographical documents.
Documents in these forms of diverse collections present additional challenges for generating readable, meaningful summaries.

Embodiment Construction

[0025]FIG. 1 is a simplified block diagram of a system for generating a document collection, generating summaries of document collections containing multiple documents having various relationships between the documents and presenting the summaries to a user in a comprehensible format. The system generally includes a document collection engine 103, a document collection database 105, a preprocessing program 110, a router program 115 and a number of document-type specific summarization engines tailored to the characteristics of expected document collection types having varying degrees and relationships of similarity. The preprocessing program 110 performs a number of tasks which, depending on application, can include content and image extraction, grouping documents into document clusters, assigning clusters to various categories and generating suitable labels for both the clusters and categories. A user interface 135, generally in the form of a graphical user interface such as an inte...

Abstract

Computer-based method of generating a summary of one or more documents comprises identifying content including text having a measurable quality from a predetermined location, evaluating the content, using a computer processor, to determine whether the content represents a document of interest, and preparing a summary of the content if the content represents document of interest. A computer-based method of generating a summary of one or more documents, each including two or more sentences, is also provided.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to automatic document collection and summarization and more particularly relates to systems and methods for generating summaries of multiple documents grouped as clusters including documents of various degrees of relatedness.BACKGROUND OF THE INVENTION[0002]The desirability of generating a summary of a document, such as an abstract, is well known. A more difficult task, yet equally desirable, is that of providing a summary of multiple documents in a document collection which are directed to a common event, person, theme and the like. Generally, such a collection of documents can span numerous sources, ranges in time and focus. The ability to generate a readable summary which conveys the content of the document collection is important to enable researchers to determine if the collection of documents pertains to the research question at hand.[0003]A number of methods for generating a summary of multiple related docume...
