Implementing a Task Specific Grammar for Recognition and Parsing using the CPK NLP Suite for Spoken Language Understanding

Abstract

This paper describes how a task specific grammar can be implemented using a dedicated "NLP" Augmented Phrase Structure (APS) grammar formalism. The APS is used for generation of appropriate semantic frames to be passed on to the dialogue manager of a spoken dialogue system. In a derived form, conforming to the HTK Standard Lattice format, the same APS may be used for constraining the approved speech recogniser grapHvite by Entropics. APS and HTK (standard lattice) are just two of several NLP and recognition grammar formats supported by the CPK NLP Suite for Spoken Language Understanding. The suite can be downloaded (in C++ source code) for research and other non-commercial use at the web address http://www.cpk.auc.dk/~tb/nlpsuite. 1. INTRODUCTION This paper is a tutorial-like introduction to the CPK NLP suite for Spoken Language Understanding. The suite has been developed and used within a number of national and international projects and supports a number of grammar formalisms. The ..
