Automatic Categorization Added in Hot Neuronís Clustify 2.0

Hot Neuron, LLC announced the release of version 2.0 of its Clustify document clustering software, which features automatic document categorization and other tools to help corporations and law firms explore and organize large document sets. Clustify groups related documents into clusters, allowing the user to explore the document set and efficiently and consistently categorize documents by categorizing 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 features added since version 1.0 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, 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.

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). Version 2.0 builds on the excellent scalability of previous versions with even faster near-duplicate detection. It also features better handling of documents having widely varying lengths, with improved conceptual analysis for very short documents.

Hot Neuron is an information retrieval software and services company located in Bryn Mawr, Pa. It owns and operates (, a search engine and directory for finding online magazine articles. For more information on Clustify, visit
