TAILIEUCHUNG - Web Semantics: Science, Services and Agents on the World Wide Web

What has received much less attention is how mega-events are related to urban processes, for they often transform urban space through the erection of landmark structures or through the renewal of urban space such as plazas or parks or new housing/ retail developments. The extensive urban waterfront development in Barcelona for the 1992 Olympics is a particularly outstanding case in point (de Moragas Spa and Botella, 1994). In any event, the mega-event (formerly called hallmark event) may be of short duration but it has an impact and meaning far beyond the event itself for the host city (Ritchie, 1984; Hall, 1997) | This article appeared in a journal published by Elsevier.

The Simple Event Model SEM is created to model events in these various domains without making assumptions about the domain-specific vocabularies used. SEM is designed with a minimum of semantic commitment to guarantee maximal interoperability. In this paper we discuss the general requirements of an event model for Web data and give examples from two use cases historic events .
