... a tree adjoining grammar as follows. A tree adjoining grammar G is a paw (i,A) where i is a set of initial trees, and A is a set of auxiliary trees. A tree a ls an initial tree if it is of ... set of alJ trees derived in G starting from initial trees in I. This set will be called the tree set of G.

... of the corresponding type. Then, if A is of type a * fl and B is of type a, the function application (AB) is a formula of type ft. Finally, if x is a variable of type a and C is a term of ... argument of such a predicate is of type ti. Predicates are to be thought of as representing sets and relations. Thus a predicate of type f * o represents a set of individua...

In situation semantics the meanlng of a sentence is a relation between various types of situations, types of discourse situations on t...

... grammars. Our approach to syntax uses a cascade of rule sequence processors, each of which can be thought of as approximating some aspect of the underlying grammar by finite-state transduc- ... spanning parses through successive stages of partial pars- ing. For the purpose of the present paper, we need to mostly be concerned with the level of analysis of core noun phra...

Instead of assuming this correspondence, we penal- ize for the lack of isomorphism between the sets of roles in aligned predicates with the penalty depen- dent on the degree of violation. This softer ... encoded as a clustering of syntactic signatures of predicate ar- guments. The clustering implicitly defines the set of permissible alternations. For predicates present...
