How do people describe events they have witnessed? What role does linguistic aspect play in this process? To provide answers to these questions, we conducted an experiment on aspectual framing. In our task, people were asked to view videotaped vehicular accidents and to describe what happened (perfective framing) or what was happening (imperfective framing). Our analyses of speech and gesture in retellings show that the form of aspect used in the question differentially influenced the way people conceptualized and described actions. Questions framed with imperfective aspect resulted in more motion verbs (e.g. driving), more reckless language (e.g. speeding), and more iconic gestures (e.g. path gesture away from the body to show travel direction) than did questions framed with perfective aspect. Our research contributes novel insights on aspect and the construal of events, and on the semantic potency of aspect in leading questions. The findings are consistent with core assumptions in cognitive linguistics, including the proposal that linguistic meaning, including grammatical meaning, is dynamic and grounded in perceptual and cognitive experience.

Anaphora processing is a central topic in the study of natural language and has long been the object of research in a wide range of disciplines. The correct interpretation of anaphora has also become increasingly important for real-world natural language processing applications, including machine translation, automatic abstracting, information extraction and question answering.This volume provides a unique overview of the processing of anaphora from a multi- and inter-disciplinary angle. It will be of interest and practical use to readers from fields as diverse as theoretical linguistics, corpus linguistics, computational linguistics, computer science, natural language processing, artificial intelligence, human language technology, psycholinguistics, cognitive science and translation studies.The readership includes but is not limited to university lecturers, researchers, postgraduate and senior undergraduate students.

The second volume in the Vancouver Studies in Cognitive Science series, this collection presents recent work in the fields of phonology, morphology, semantics, and neurolinguistics. Its overall theme is the relationship between the contents of grammatical formalisms and their real-time realizations in machine or biological systems. Individual essays address such topics as learnability, implementability, computational issues, parameter setting, and neurolinguistic issues. Contributors include Janet Dean Fodor, Richard T. Oehrle, Bob Carpenter, Edward P. Stabler, Elan Dresher, Arnold Zwicky, Mary-Louis Kean, and Lewis P. Shapiro.

Purpose - This paper aims to provide an overview of principles and procedures involved in creating a faceted classification scheme for use in resource discovery in an online environment.Design methodology approach - Facet analysis provides an established rigorous methodology for the conceptual organization of a subject field, and the structuring of an associated classification or controlled vocabulary. This paper explains how that methodology was applied to the humanities in the FATKS project, where the objective was to explore the potential of facet analytical theory for creating a controlled vocabulary for the humanities, and to establish the requirements of a faceted classification appropriate to an online environment. A detailed faceted vocabulary was developed for two areas of the humanities within a broader facet framework for the whole of knowledge. Research issues included how to create a data model which made the faceted structure explicit and machine-readable and provided for its further development and use.Findings - In order to support easy facet combination in indexing, and facet searching and browsing on the interface, faceted classification requires a formalized data structure and an appropriate tool for its management. The conceptual framework of a faceted system proper can be applied satisfactorily to humanities, and fully integrated within a vocabulary management system.Research limitations implications - The procedures described in this paper are concerned only with the structuring of the classification, and do not extend to indexing, retrieval and application issues.Practical implications - Many stakeholders in the domain of resource discovery consider developing their own classification system and supporting tools. The methods described in this paper may clarify the process of building a faceted classification and may provide some useful ideas with respect to the vocabulary maintenance tool.Originality value - As far as the authors are aware there is no comparable research in this area.
