Really good to see the latest Mental Health demonstrator from the ASSERT project: http://nactem3.mc.man.ac.uk:8080/ASSERT_Refactored/. I really like the visualisation - I think this will really help social scientists get to grips with text mining and has the potential to facilitate and speed up the systematic review process.
And in a nice join up between two of my projects (NaCTeM and CO-ODE), NaCTeM has released its TerMine Plugin for Protégé. The plugin "uses text mining tools to extract candidate terms from a corpus of text and provides an interface for rapidly bringing these terms into an OWL ontology. It uses the TerMine term extraction tool provided by NaCTeM to extract concepts from text. The plugin accesses TerMine via a Web Service over the Internet."
The plugin can be downloaded from http://www.co-ode.org/downloads/protege-x/plugins/
Also worth mentioning the Kleio demonstrator http://nactem4.mc.man.ac.uk:8080/Kleio/ developed from Phase 1 of NaCTeM.
