encoding and acquiring meanings

... Generalization and Refinement Phrases are acquired in a process of hypothesis formation and error correction. The program generates and refines hy- potheses about both the linguistic pattern, and the ... of each phrase. This paper is concerned in the representation of phrase meanings and the process of acquiring these meanings from examples in context. * This research was supported in part ... request, and on the other hand, John read the riot act implies that he reacted angrily about a certain event in the past.
