Lightweight Community-Driven Approach to Support Ontology Evolution Essay

Lightweight Community-Driven Approach to Support Ontology maturation - Essay ExampleThe chapter goes on to identify the advantage of ontology evolution, the lack of systematic approach for ontology evolution and explains the need for this study. The chapter ends with the objectives of the study and thesis structure. 1.2 Ontology Definitions The term Ontology is derived from its usage in philosophy where it means the study of being or existence as well as the basic categories (Witmer 2004). Therefore, it is now used to refer to what exists in a system model. Definition 1 According to the Merriam-Webster Dictionary (2011), It is a particular nature of being or the kinds of things that have existence. Definition 2 Gruber (1993), on the other hand, provides a more concrete definition of Ontology. He defines it as a study which explicitly explains concepts and relationships (Gruber 1993). The set of concepts (e.g. classes, relations, functions) are used to represent and describe field knowledge. For example, in oil and gas industry there is an established ontology for Statoil in Norway (Association 2008) a standard subroutine library related to an oil and gas do chief(prenominal). 1.3 Ontology Editor Ontology Editor is an application which is developed to view and edit ontology. In the past few years many applications have been developed such as OilEd (Bechhofer, Horrocks et al. 2001), OntoEdit (Sure, Erdmann et al. 2002), Protege (Gennari, Musen et al. 2003) and Web-Protege (Tudorache, Vendetti et al. 2008). come on details are explained below about each ontology editor - OilEd OilEd was developed in Manchester University. It is a simple ontology editor that provides further guidance in the development of Ontology Interchange Language (OIL)-based ontologies (Bechhofer, Horrocks et al. 2001), which is essentially a web-based representation of ontologies organized to make it accessible and usable (Cover, 2000). It is the one which pioneers ontology editing (Bec hhofer, Horrocks et al. 2001). - OntoEdit OntoEdit was developed by the Knowledge Management Group at University of Karsnuhe Institute AFIB. It provides an ontology development that allows collaboration and inferencing. The method involves three main steps which start with requirements specification, last and evaluation. The first step is where the ontology engineers and domain experts meet and wrick towards identifying the goal of the ontology, definition of the domain, and the availability of references. Design guidelines are also established in this step. Then, the team then makes the ontology in the refinement phase. Finally, the ontology requires evaluation according to its requirements specification by identifying possible errors in the ontology and efficiency for enabling collaborative work (Sure, Erdmann et al. 2002). - Protege Protege was developed by Mark Musen at Stanford University. It is an ontology editor which has come a long way. Protege started in 1987 as a small application, which was aimed at building knowledge acquisition tools. Protege has then been developed further, providing many in the raw features for each mutant that has been released. Currently, there are hundreds of individuals and research groups are using Protege (Gennari, Musen et al. 2003). - Web-Protege Web-Protege is a web version of Protege, also developed in Stanford University. This allows the users who have access to view and edit the ontology from the internet (Tudorache, Vende
