Modelling the “Information Aspect” of Human Purposeful Activities
The process of information systems development seems lacking an information modelling stage, which requires a concrete expression of information. This paper suggests to use predicate logic to express items of information, and to use Barwise and Devlin’s situation theory to model the information aspect of a human purposeful activity as a remedy of the problem. The idea is to capture the information flow in a human purposeful activity from the point of view of the ‘actor’, an agent who performs the activity, by means of a set of formal concepts. This ‘information aspect’ will capture the information requirements of the actor for accomplishing the activity, and provides a basis for objects and data identification.
