Change operators are the building blocks of ontology evolution. Different layers of change operators have been suggested. In this paper, we present a novel approach to deal with ontology evolution, in particular, change representation as a pattern-based layered operator framework. As a result of an empirical study, we identify four different levels of change operators based on the granularity, ...

Business change designates one of the most conspicuous and most pervasive features of organisational life. However, there has been very little consideration of business change in itself, rather the emphasis has been on studying the outcomes of this change. This paper focuses on a subset of business change which is centred on the information flows of the organisation and is stimulated by catalys...

karun river with a length of about 890 km is considered as a main river in the country. in this paper, types of karun’s screws regarding to the geometric factors of radius of curvature and chord length were identified by fitting circles with the arcs of the river’s axis. river’s arcs were classified into simple and compound screws. then, by formation of the database consist of topographic...

You get a raise on 1 March but the system doesn’t find out about it until mid-May. In the meantime, who knows what happens? Reconciling these two time lines, world time and system time, is one of the most difficult problems to solve in writing information systems. Many of the actions in business are irreversible. It is complicated and expensive to take an incorrect check back. To “make the chec...

Automatic change pattern mapping in urban and sub-urban area is important but challenging due to the diversity of urban land use pattern. With multi-sensor imagery, it is possible to generate multidimensional unique information of Earth surface features that allow developing a relationship between a response of each feature to synthetic aperture radar (SAR) and optical sensors to track the chan...

Change is recognized as being intrinsic to ecosystems, but is also the essence of instability and the outgrowth of situations that lack sustainability. Change is arguably the most fundamental symptom for onset of abnormality in ecosystem function, and change in change cannot be detected without sufficient monitoring to determine spatial and temporal aspects of characteristic change regimes acro...

Service-based architectures have become commonplace, creating the need to address their systematic maintenance and evolution. We investigate architecture change representation, primarily focusing on the identification of change patterns that support the potential reuse of common changes in architecture-centric evolution for service software. We propose to exploit architecture change logs captur...

While there exist OWL ontologies that capture events and acknowledge the dynamic nature of certain domains, the possibility of change is neglected in many domain-specific ontologies. Solutions to the representation of fluents have been proposed, however there exists no guidance for the average Semantic Web practitioner on how to incorporate these solutions into existing ontologies or implement ...

INTRODUCTION "Change-glasses" approach in pattern recognition [1] relies on the assumption that there are subspaces of the initial feature space where the chosen classification rule can be replaced by another, more competent, one (see, e.g. [2]). This will hopefully lead to a better classification accuracy in comparison with that obtained through one rule only. This classification strategy bear...
