Formal Concept Analysis (FCA) is an exploratory data analysis technique for boolean relations based on lattice theory. Its main result is the existence of a dual order isomorphism between two set lattices induced by a binary relation between a set of objects and a set of attributes. Pairs of dually isomorphic sets of objects and attributes, called formal concepts, form a concept lattice, but ac...

By incorporating aspects of coordination and collaboration, workflow implementations of information systems require a sound conceptualisation of business processing semantics. Traditionally, the success of conceptual modelling techniques has depended largely on the adequacy of conceptualisation, expressive power, comprehensibility and formal foundation. An equally important requirement, particu...

Over time there has been a shift, at least in the rhetoric, from a pipeline conceptualisation of knowledge implementation, to one that recognises the potential of more collaboration, co-productive approaches to knowledge production and use. In this editorial, which is grounded in our research and collective experience, we highlight both the potential and challenge with collaboration and co-prod...

This paper investigates an approach to human-computer interaction – actability theory – that emphasises human-via-computer-to-human interaction. This social action approach to HCI is confronted with affordance theory by Gibson; an ecological theory of perception. The notion of affordance is compared and related to actability. Different IT usage situations described in actability theory are crit...

The issues raised by the design and development of technologies to enhance learning has led to a demand for an appropriate language and form of conceptualisation. However we are insufficiently familiar with the way in which different types of mediated tool use occur, to develop the theoretical models needed for the development of this language and form of conceptualisation. In its absence a som...

In practice, domain-specific modelling is intended for improved conceptualisation of a specific domain. Further, distinct parts of a large software system are modelled by different domain-specific modelling languages. This approach sometimes leads to the problem of poor semantics, interoperability and reusability of domain model concepts. However, ontology aids in common understanding of domain...

Some economists find markets everywhere and assume that they emerge spontaneously once a set of necessary conditions such as well-defined property rights is fulfilled. Others emphasise the role of organisations and contend that markets are actually less dominant. But despite claims to the contrary, the market concept is hardly analyzed in depth. Nor are there serious attempts to examine empiric...

Metaphors are an undeniable part of many forms of art and they hint at the underlying conceptualisation that takes place in the silent conversation between an art piece and its perceiver. Abstract art, in particular, requires the viewer not only to analyse the colour palette and the shapes of the strokes but to subconsciously react to the underlying structures that often define the metaphors. A...
