CALO is in the news. I heard about it from Adam Cheyer about four years ago, when it was just starting. In fact, we were looking at integrating HyperScope into it some how. May still be a good idea.
CALO is a massive, four-year-old artificial-intelligence project to help computers understand the intentions of their human users. Funded by the Defense Advanced Research Projects Agency (DARPA), and coordinated by SRI International, based in Menlo Park, CA, the project brings together researchers from 25 universities and corporations, in many areas of artificial intelligence, including machine learning, natural-language processing, and Semantic Web technologies. Each group works on pieces of CALO, which stands for “cognitive assistant that learns and organizes.”
