Automatic categorization

Hot Neuron has released Version 2.0 of its Clustify document clustering software, which automatic document categorization and other tools to help corporations and law firms explore and organize large document sets.

The company explains that Clustify groups related documents into clusters, allowing the user to explore the document set and categorize entire clusters of documents with a single mouse click. The addition of automatic categorization further leverages any manual labor put into categorization by automatically categorizing new documents based on the categories assigned to similar documents that were categorized in the past. Documents that aren't sufficiently similar to previously categorized documents are put into clusters for efficient manual processing.

Other new features include:

• keyboard shortcuts for faster manual categorization,
• the ability to drag and drop one document onto another to display a side-by-side comparison that highlights common text, and
• options for greater control over the clustering process, and handling of many additional file formats on Windows via the same IFilter technology that is used in Microsoft's search products.

Further, says Hot Neuron, Clustify can generate concept-based clusters, or it can require documents in the same cluster to contain identical passages of text in order to detect near-duplicates (i.e. different revisions of the same document).
