The PUBLIC website for the CTSA Health Ontology Mapper SHRINE integration is located here: however the caGRID based site has not been made public yet (not because it's secret or anything but we haven't had the time yet).

The Ontology Mapper project has been very active from its inception and our work continues at a brisk pace.

We are now working on version 2: This project is currently making our tools interoperable with both SHRINE and the NCBO BioPortal with the OpenMDR TRIAD system at OSU.  We have an active project under way to allow the command line operation of UETL and HOM from batch job processing environments and there is an exploratory project that would allow NLP extraction of biomedical concepts from incoming full text data fields.
