Natural Language Understanding: Integrating Syntaz, Semantics, and Discourse
Objeeti~ea: (1) Creation of an integrated, portable system for the detailed understanding of multi-paragraph text and messages. (2). Develop a principled computational treatment of semantic and discourse phenomena, including treatment of reference and temporal information. (3) Development of an integrated loglc-based analysis algorithm which uses syntactic, semantic and discourse information to...
متن کاملIntegrating Speech and Natural Language
The overall goal of this project is to integrate speech and natural language knowledge sources to build a speech understanding system for human-machine communication using spoken English. The speech knowledge sources use acoustic models based on hidden Markov modeling techniques. The natural language knowledge sources use a Unification grammar formalism for describing the syntax of English, a h...
متن کاملIntegrating Natural Language Subtasks with Bayesian Belief Networks
The development of automatic natural language understanding systems remains an elusive goal. Given the highly ambiguous nature of the syntax and semantics of natural language, it is often impossible to develop rule{based approaches to understanding even very limited domains of text. The diiculty in specifying rules and their exceptions has led to the rise of probabilistic approaches where model...
متن کاملGenerating Contextually Appropriate Intonation
One source of unnaturalness in the output of text-to-speech systems stems from the involvement of algorithmically generated default intonation contours, applied under minimal control from syntax and semantics. It is a tribute both to the resilience of human language understanding and to the ingenuity of the inventors of these algorithms that the results are as intelligible as they are. However,...
متن کاملSituations and Intervals
The PUNDIT system processes natural language descriptions of situations and the intervais over which they hold using an algorithm that integrates ~peet and ~en~e [ogle. It analyzes the tense and aspect of the realverb to generate representations of three types of situations-states, processes and events-and to locate the situations with respect to the time at which the text was produced. Each si...
