An utterance is normally produced by a speaker in linear time and the hearer normally correctly identifies the speaker intention in linear time and incrementally. This is hard to understand in a standard competence grammar since languages are highly ambiguous and context-free parsing is not linear. Deterministic utterance generation from intention and n-best Bayesian interpretation, based on the production grammar and the prior probabilities that need to be assumed for other perception do much better. The proposed model uses symbolic grammar and derives symbolic semantic representations, but treats interpretation as just another form of perception. Removing interpretation from grammar is not...
This book presents important results from the ESPRIT Project 393 "Construction and Interrogation of Knowledge Bases Using Natural Language Text and Graphics" (ACORD). The project involved more than fifty people overfive years, and included industrial and academic partners from three countries. The main result of the project is a highly sophisticated human-machine interface allowing the construction and interrogation of a common knowledge base in English, French, and German, using both natural language and graphics. Chapter 1 presents an overview of the project. Chapters 2-4 develop specific issues concerning thegrammar models used (functional grammars and unification categorial grammars). Chapter 5 discusses anaphora resolution and Chapter 6 text generation. Chapter 7 explains the integration of text and graphics, and Chapter 8 discusses the knowledge base module. The contributions are theoretically oriented and strongly concerned with generalization and the underlying background of potential further developments.
Bidirectional Optimality Theory (BiOT) emerged at the turn of the millennium as a fusion of Radical Pragmatics and Optimality Theoretic Semantics. It stirred a wealth of new research in the pragmatics-semantics interface and heavily influenced e.g. the development of evolutionary and game theoretic approaches. Optimality Theory holds that linguistic output can be understood as the optimized products of ranked constraints. At the centre of BiOT is the insight that this optimisation has to take place both in production and interpretation, and that the production-interpretation cycle has to lead back to the original input. BiOT is now generally interpreted as a description of diachronically stable and cognitively optimal formmeaning pairs. It found applications beyond the semantics-pragmatics interface in language acquisition, historical linguistics, phonology, syntax, and typology. This book provides a state of the art overview of these developments. It collects nine chapters by leading scientists in the field.
Castel Ivano, originally built in 1375, is one of many beautiful and impressive castles strategically placed atop hills in Trentino's Valsugana in Northern Italy. It was in this castle on a series of brilliant sunny crisp November days in 1990 that an international group of computer scientists and cognitive scientists met at a workshop to discuss theoretical and applied issues concerning communi cation from an Artificial Intelligence and Cognitive Science perspective. About forty people, representing nine countries, participated in the workshop, either as speakers, discussants, or observers. The main motivationfor the workshop wasto address the questionofwhether and how current computational...
This book presents current research that discusses some of the major issues in pragmatics from new perspectives, and directs attention to aspects of fundamental tenets that have been investigated only to a limited extent. Current pragmatic theories emphasize the importance of intention, cooperation, common ground, mutual knowledge, relevance, and commitment in executing communicative acts. However, recent research in cognitive psychology, linguistic pragmatics, and intercultural communication has raised questions that warrant some revision of these major tenets. Debates about the place of intention in pragmatics have indicated that Gricean intentions may play a less central role in communica...
'The Oxford Handbook of Linguistic Interfaces' explores how the core components of the language faculty interact. This book shows how these interactions are reflected in linguistic and cognitive theory, considers what they reveal, and looks at their reflections in expression and communication.
The book addresses a controversial current topic in language acquisition studies: the impact of frequency on linguistic structure in child language. A major strength of the book is that the role of input frequency in the acquisition process is evaluated in a large variety of languages, topics and the two major theoretical frameworks: UG-based and usage-based accounts. While most papers report a clear frequency effect, different factors that may be interacting with pure statistical effects are critically assessed. An introductory statement is made by Thomas Roeper who calls for caution as he identifies frequency as a non-coherent concept and argues for a precise definition of what can and cannot be explained by statistical effects.
presupposition fails, we now give a short introduction into Unification Grammar. Since all implementations discussed in this volume use PROLOG (with the exception of BlockjHaugeneder), we felt that it would also be useful to explain the difference between unification in PROLOG and in UG. After the introduction to UG we briefly summarize the main arguments for using linguistic theories in natural language processing. We conclude with a short summary of the contributions to this volume. UNIFICATION GRAMMAR 3 Feature Structures or Complex Categories. Unification Grammar was developed by Martin Kay (Kay 1979). Martin Kay wanted to give a precise defmition (and implementation) of the notion of 'f...
Sense and Sensitivity advances a novel research proposal in the nascent field of formal pragmatics, exploring in detail the semantics and pragmatics of focus in natural language discourse. The authors develop a new account of focus sensitivity, and show that what has hitherto been regarded as a uniform phenomenon in fact results from three different mechanisms. The book Makes a major contribution to ongoing research in the area of focus sensitivity – a field exploring interactions between sound and meaning, specifically the dependency some words have on the effects of focus, such as "she only LIKES me" (i.e. nothing deeper) compared to "she only likes ME" (i.e. nobody else) Discusses the f...
