We go beyond simple propositional meaning extraction and present experiments in determining which propositions in text the author believes. We show that deep syntactic parsing helps for this task. Our best feature combination achieves an Fmeasure of 64%, a relative reduction in Fmeasure error of 21% over not using syntactic features.

We present a generalized committed choice construct for concurrent programs that interact with a shared store. The generalized committed choice (GCC) allows multiple computations from different alternatives to occur concurrently and later commit to one of them. GCC generalizes the traditional committed choice in Dijkstra’s Guarded Command Language to handle don’t know non-determinism and also a...
