“…As my work is from an information systems viewpoint, I have focussed on the information systems definition of situations. Barwise (1987), Akman and Surav (1996), Adi et al (2002) and Fischer et al (2002) provide definitions that initially appear to be quite different, however they all take context into account, either explicitly or implicitly, and they all consider the state of things in the context.…”

“…Rules need to be defined to specify the appropriate actions that should be taken in response to occurrences of each reactive situation (Adi et al, 2002). Where the same response is required for a number of reactive situations, these situations form a class or type of situation (Cherry, 2001) for which reaction rules must be defined.…”

“…• Whether and under what conditions an event is consumed (Adi et al, 2002) Adi and Etzion's event class does not include any location attributes. For mobile users it must be extended to include at least location attributes and most likely, other attributes of context.…”

This paper introduces a novel design artefact, namely a generic situation management ontology based on situation theory. This ontology contributes to the foundation knowledge base of mobile service delivery systems for future research and systems design. It demonstrates the applicability, and feasibility of using situation theory in the design of reactive information systems. The support within the ontology for context based filtering for situation detection also contributes to the efficiency of implementation and operation of situation driven reactive information systems.Highly mobile people (HMPs) require flexible, reactive service delivery due to their regularly changing location and activities and the lack of a wired network connection. A mobile service delivery system should be able to detect relevant events that occur such as change of location, availability of new last-minute specials, sales opportunities and safety issues and then reactively take action in response to these events. This paper describes a generic situation management ontology that was developed in OWL using the ontology development tool, Protégé. The ontology is combined with domain specific classes in the travel domain to create a travel situation management ontology that can be used as the basis for a ubiquitous mobile travel service application. Using a typical independent traveler scenario, the travel situation management ontology is instantiated to demonstrate its effectiveness.

“…While they are similar, they differ according to the viewpoint of the researcher. As this work is from an information systems viewpoint, it has drawn upon the work of Barwise (1987), Akman and Surav (1996) , Adi et al (2002) and Fischer et al (2002). They provide definitions that initially appear to be quite different, however, they all take an information systems perspective, taking context into account, either explicitly or implicitly, and they all consider the state of things in contexts.…”

“…Situations that do require some action to be taken, that is, reactive situations, require action rules to be defined. In this work the following, slightly modified version of Barwise's definition (Barwise, 1981): "a situation is a state of affairs in a particular context" was adopted but it draws upon Adi et al's work (Adi et al, 2002) to define reactive situations.…”

A Travel Situation Management Ontology

Highly mobile people (HMPs), such as international executives, airline crew, international sportspersons and independent travellers require flexible, reactive service delivery due to their regularly changing location and activities and the lack of a wired network connection. A mobile service delivery system should be able to detect relevant travel-related events such as change of location, availability of new last-minute specials, sales opportunities and safety issues and then reactively take action in response to those events. This paper describes a generic travel situation management ontology that was developed in the Ontology Language for the World Wide Web (OWL) using the ontology development tool, Protégé. This ontology can be used as the basis for mobile travel service applications.
