The AAAI-17 workshop program included 17 work-shops that covered a wide range of topics in AI and were an excellent forum for exploring emerging approaches and task areas, for bridging the gaps between AI and other fields or between subfields of AI, for eluci-dating the results of exploratory research, or for cri-tiquing existing approaches. Workshops were held Sun-day and Monday, February 4–5, 2017, at the Hilton San Francisco Union Square in San Francisco, California, USA. Workshop participants met and discussed issues with a selected focus — providing an informal setting for active exchange among researchers, developers, and users on topics of current interest. To foster interaction and exchange of ideas, the workshops were kept small, with 25–65 participants. Attendance was sometimes limited to active participants only, but most workshops also allowed general registration by other interested individ-uals. Most of the workshops were held on a single day. Of the 17 workshops held, all but 2 (Increasing Diver-sity in AI and Developing Artificial Intelligence Startup Companies) were included in the AAAI digital library as technical reports.
