System And Method For Forming Spines Of Document Clusters With The Aid Of A Digital Computer

A system for forming spines of document clusters with the aid of a digital computer, comprising:

• concepts for each of a plurality of document clusters;
• a server comprising a central processing unit, memory, an input port to receive the concepts, and an output port, wherein the central processing unit is configured to:
• select candidate spines for placement of at least a portion of the document clusters based on the concepts, comprising:
• determine the concepts generated for each document cluster;
• for each concept, determine a number of other document clusters for which the concept is generated;
• identify those concepts that are generated for more than a single document cluster and that are generated for less than a threshold number of the document clusters;
• and
• designate the identified concepts as candidate spine concepts and form the candidate spines based on the candidate spine concepts;
• and
• assign other clusters to the candidate spines based on the candidate spine concepts.
