Benefits of technology

[0007]It is a further object of the invention to provide a system which enables a user to browse large quantities of content, such as news articles, through categorization, clustering and summarization of the 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 are 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

System for generating a summary of a plurality of documents is provided. The system includes a computer readable document collection containing a plurality of related documents stored in electronic form therein, a plurality of forms of multiple document summarization engines, and a router for determining a temporal relationship of at least a subset of the documents in the collection and selecting one of the plurality of forms of multiple document summarization engines for generating a summary of the subset of documents based on the temporal relationship.

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...
