Toward a Canonical Method to Solve Patterns of Ontology Modelling Issues 2 ____________________________________________________________________________________________________________UNIVERSITY OF SOUTHAMPTONABSTRACT Faculty of Engineering, Science and Mathematics School of Electronics and Computer Science Intelligence, Agents, Multimedia Group and Dependable Systems and Software Engineering Group Nine month progress report submitted for continuation towards a PhD by Benedicto RodriguezThis report presents a brief description of the different activities carried out in the field of ontology engineering. It identifies a lack of guidelines on how to address modeling issues during the ontology conceptualization phase, in the current methodologies to build ontologies from scratch. It describes an example scenario of an ontology modeling task and it proposes a possible solution inspired by folksonomy based systems and faceted classification. This is followed by a study of the difficulties found to adapt the IEEE Learning Object Metadata (LOM) standard to model an ontology fit for purpose in a specific university curricula domain. It also gives an example of a prototype for a potential next generation semantic web application and a brief summary of the main viewpoints that will characterize such applications. Finally it outlines possible paths of further research to address ontology modeling issues and it suggests looking at various sources for possible solutions (schemes of folksonomy and faceted classification, design principles of object-oriented and relational database applications, and ontology evaluation).

Toward a Canonical Method to Solve Patterns of Ontology Modelling Issues 4 ____________________________________________________________________________________________________________1. IntroductionThe original idea at the beginning of this PhD program was to evaluate and understand the current state of knowledge technologies, specifically ontology engineering, and assess if these technologies could be applied to the field of software engineering to assist development teams in improving the quality of the artifacts delivered along the software development process. The evaluation of the current state of ontology engineering, uncovered new areas of research interest linked to some of the difficulties encountered when following any of the methodologies available to create ontologies. One of such problems was laying out the initial ontology model once the glossary of terms pertaining to the domain knowledge was already available. Ontology creation methodologies provide some guidelines on how to approach this design step however they do not seem to provide enough level of detail on how to address certain modeling issues. This deficiency could lead ontology designers into making incorrect modeling choices having to rely on a subjective interpretation of the problem. The aim of this research is to explore this aspect of the ontology creation process in depth and try to propose better guidelines that could assist ontologists in solving specific design issues in a more deterministic, reproducible and objective manner.
