IBM Watson

Watson and Jose Luis Preza Diaz I have successfully implemented Watson APIs within the Phaidra Analytics platform for real time information enrichment of digital objects stored in a repository. I am invited to Keynote this integration in an upcoming Metadata Conference in June here at the University of Vienna and probably in Semantics Leipzig in September this year. IBM has expressed interest on this work as well.
