BUILDING LINEAGES OF DOCUMENTS

A system for organizing a collection of documents from multiple sources, identifying which are different versions of the same content, and using metadata from those documents to provide an ordered collection to display the iterations as a lineage. For text-based documents the system determines which documents are different versions of the same using content analysis techniques. For non-text-based documents, a different mechanism based on file names is performed that detects common conventions for iterating on file names.
