Dialogue Act Modelling for Analysis and Specification of Web-Based Information Systems

Web-based information systems aim to enable people to live and do things in society with help of computer systems on internet. User interfaces and navigation structures of these systems become more important and critical than the ones of traditional information systems to the user because of the nature and specific characteristics of these systems. The experiences on requirements analysis and specification of these systems have shown the need of gathering and specifying communicational requirements for these systems in the analysis model as a basis for designing user interfaces and navigation structures. This paper addressed this issue and proposes a dialogue act modelling approach that has focus on communicational requirements with pragmatic and descriptive views in terms of the Speech Theory in social science and the object modelling techniques in Software Engineering.
