Abstract The project is concerned with the foundations of natural language interpretation and its consequences for knowledge representation, focusing on the themes of partial information and dynamic interpretation, with attention to the goal of developing a formal theory of natural language interpretation which admits computational implementation. DYANA II is a continuation of DYANA (3175).


Aims

The specific objectives of DYANA-2 are four-fold: (i) To determine those aspects of the structure of information states which are relevant to natural language interpretation; (ii) To examine specific semantic and pragmatic phenomena which currently prevent the effective use of natural language in human-computer interaction; (iii) To develop sufficient understanding of the logical and computational properties of sign-based grammar architectures to allow application across all components of the grammar; (iv) To demonstrate the utility of sign-based grammar architecture by providing a principled account of cross-linguistic variation.

Approach and Methods

Research is carried out on an interdisciplinary, collaborative basis drawing on concepts and tools from linguistics, logic, artificial intelligence and computer science. The work is divided into three interdependent themes:

Progress and Results

In its first year the DYANA consortium has shown results in the following areas:

Potential

The research themes that constitute the DYANA project aim to meet some of the challenges that lie ahead on the way towards computer systems that use natural language. Although the major aim of the project is to carry out fundamental research in natural language processing, work is also directed towards the development of prototypes and proof-of-concept implementations. A DYANA Newsletter is published which contains up to date information about recent publications, new deliverables, and DYANA-related workshops.

Latest Publications

Information Dissemination Activies

A DYANA Newsletter is published every six months which contains up to date information about recent publications, new deliverables, and DYANA related workshops. At relevant occassions members of the DYANA consortium make DYANA more widely known using The Hyperdyana Illustration Set.
