A couple of weeks ago I handed out a short list of talks that seemed to have something to do with semantics. However, in the meantime there have been a couple of changes. So: Don’t trust the locations (particularly) on the handout, trust the online schedule instead.
Systematically, things labeled “B” on my handout will meet in the East Balcony as part of session C, things labeled “C” will meet in the Conference Auditorium as part of session B, and things labeled “A” will meet in Metcalf Small as part of session A.
