In this paper, we present a novel unifying concept of pairwise spatial relations. We develop two way directional relations with respect to a unique point set, based on topology of the studied objects and thus avoids problems related to erroneous choices of reference objects while preserving symmetry. The method is robust to any type of image configuration since the directional relations are top...

Information Systems (IS) should be based on consistent representations of the reality. Poor modeling results in problems throughout the IS development. Ontologies are key instruments for the improvement of conceptual modeling since they are able to provide well-defined semantics. This paper discusses the application of foundational ontologies in conceptual modeling, presenting partial results o...

Ontologies define a specific vocabulary to describe a certain reality, while Context is knowledge that helps to identify what is relevant in a given situation. Among the classifications, there are task and domain ontologies, which combined, produce a vocabulary that describes concepts related to a set of applications that work by performing a particular task in a related field. Currently, few s...

Many economists and social scientists have recently emphasized the importance of government policies, economic, political and legal institutions, and more broadly, the organization of society.1 There is also mounting evidence that various institutional features are indeed important for economic growth.2 Nevertheless, despite important theoretical advances, we still lack an organizational framew...

Data warehouse is used to provide effective results from multidimensional data analysis. The accuracy and correctness of these results depend on the quality of the data. To improve data quality, data must be properly extracted, transformed and loaded into the data warehouse. This ETL process is the key to the success of a data warehouse. In this paper we propose a conceptual ETL framework for a...

OPEN is the premier third-generation, process-focussed, public domain OO methodology. It is documented in a number of professional-level texts. In this tutorial, a beginner’s level presentation, OPEN is introduced through a number of case studies using UML as the notation. Biography: BRIAN HENDERSON-SELLERS is a Professor of Computer Science at the University of Technology, Sydney. He is author...
