Cooperating constructions

Optimality theoretic (OT) syntax (Dekkers et al. 2000, Legendre et al. 2000, Sells 2001) is an important development in the world of constraint based grammar, because it introduces a new way of looking at constraint interactions. The leading idea is that not all constraints are “surface true” – constraints may be violated when they have to be in order to satisfy some more important, higher rank...

Bidirectional Cooperating Distributed Grammar Systems Bidirectional Cooperating Distributed Grammar Systems

We consider bidirectional cooperating distributed (BCD) grammar systems in the sense of Asveld. Independently of their mode , , =, , or t, BCD grammar systems with two components characterize the re-cursively enumerable languages even with right-linear rules and without-productions. This sharply contrasts earlier results on solely generating or accepting grammars, where right-linear rules alway...

Learning by Cooperating Agents

Most algorithms for learning and pattern discovery in data assume that all the needed data is available on one computer at a single site. This assumption does not hold in situations where a number of independent databases reside on different nodes of a network. These databases cannot be moved to a common shared site due to size, security, privacy, legal, and data-ownership concerns but all of t...
