Syntactic and Semantic Knowledge in the DELPHI Unification Grammar

Development of a Spoken Language System

We developed and used a data collection facility to collect 2277 utterances from 62 subjects. We were the only site to reach the data collection goals by the original deadline of 1 September. We completed an initial version of a new DELPHI NL system, which incorporates a semantic component integrated with the unification-based syntactic grammar, but separated from it. This allows for multiple s...

Syntactic/Semantic Coupling in the BBN DELPHI System

We have recently made significant changes to the BBN DELPHI syntactic and semantic analysis component. These goal of these changes was to maintain the fight coupling between syntax and semantics characteristic of earlier versions of DELPHI, while making it possible for the system to provide useful semantic interpretations of input for which complete syntactic analysis is impossible. Semantic in...

Semantic tree unification grammar: a new formalism for spoken language processing

In this paper we present the Semantic Tree Unification Grammar (STUG) which is a new formalism for parsing spoken language. The main motivation of this formalism is the combination of the robustness and simplicity of the classical semantic grammar to the deepness of the traditional syntactic formalisms. The key properties of STUG are: the direct linearization of the semantic structure, an econo...

The two be's of English

This  qualitative  study  investigates  the  uses  of  be  in  Contemporary  English.  Based  on  this  study, one  easy  claim  and  one  more  difficult  claim  are  proposed.  The  easy  claim  is  that  the  traditional distinction between be as a lexical verb and be as an auxiliary is faulty. In particular, 'copular-be', traditionally considered to be a lexical verb, is in fact a prototypi...
