Traditionally, the most imPortant input to the dialogue management component of a natural language system are semantic representations (e.g., formulae of first-order predicate calculus). Only recently, other kinds of information (e.g., phonetic transcriptions of unknown words) has been used. There is, however, room for the utilization of additional knowledge sources.

Explicit fusions provide a small-step account of reaction in process calculi such as the pi calculus and the fusion calculus. In this respect they are similar to the explicit substitutions of Abadi, Cardelli and Curien, wh...
متن کاملTransformed fusions
or most normal mammalian cells, survival depends on attachment. By binding to integrins, many extracellular matrix proteins activate survival pathways that prevent detachment-induced apoptosis. But on page 559 Todorovic et al. reveal a matrix molecule that kills instead. This death matrix protein, CCN1, is selective in its carnage. Endothelial cells are known to thrive on CCN1, but the group no...
