Updated Competency Questions<\/strong><\/h4>\n

Purpose<\/strong><\/p>\n

The ontology is developed to represent concepts required for the design of a sports complex.\u00a0This civil system\u00a0includes\u00a0four sub systems which are\u00a0student’s sport venue, accommodation for the students, accommodation for the employees’\u00a0and eating facility\u00a0.\u00a0The\u00a0development of the ontology\u00a0was based on previous research conducted on the technical details of the four separate systems.<\/p>\n

Scope<\/strong><\/p>\n

The ontology will represent concepts such as components, functions, infrastructures, features, use, users, environmental aspect and elements of a sports complex. Furthermore, it will represent possible interaction the sub parts of the sports complex with each other and with their environment. Each of the concept along with their relationship will be represented in the ontology.<\/p>\n

I<\/strong>ntended\u00a0<\/strong>u<\/strong>sers<\/strong><\/p>\n

The ontology developed for a\u00a0sports complex\u00a0will have many benefits in future design of such facilities. Public and private schools or collages, architects and engineers and other players in the design of a\u00a0sports complex are the intended end-users of the ontology.<\/p>\n

Schools or universities can use it to identify and sort their need. They will have the necessary knowledge of the components of a sports complex, its required features, expected use, environmental interaction, and the relationship between these concepts.<\/p>\n

Intended use<\/strong><\/p>\n

The ontology is intended to be used as knowledge representation to support the design of a\u00a0sports complex that include four main sub parts which are discussed on previous paragraphs.<\/p>\n

Integrating the Ontologies<\/strong><\/h4>\n

The integration of the\u00a0four individual ontologies (High school gymnasium<\/a>, Restaurant Design<\/a>,\u00a0 Single Story House<\/a> and Student Residence Building<\/a>) included few necessary steps. These are\u00a0combining, aligning, re-organizing and extending.<\/p>\n

1. Combining Ontologies<\/strong><\/p>\n

To begin the integration process, the four individual ontologies were all opened in a single prot\u00e9g\u00e9 window. Then, using prot\u00e9g\u00e9\u00a0natives merging tool (‘Merge ontologies’), the were merged into a single ontology. At this point we had our first copy of the combined ontology which we called ‘Sports Complex Ontology’.<\/p>\n

At this early stage, the combined ontology had 243 classes, 89 object properties, 59 data properties, 79 individuals and 1430 Axioms<\/strong>.\u00a0<\/em>However there\u00a0is more actions required to make the ontology ready for use.<\/p>\n

The first challenge encounter after the combining the ontologies was the difference in the naming convention. As shown on the picture below, the Single story house ontology (Top left figure) used a different naming system than the rest of the ontology. Since 3 out of the4 ontologies used\u00a0PascalCase<\/strong> naming convention, the same was applied to the single story house ontology.<\/p>\n

2.\u00a0Alignment<\/strong><\/p>\n

Our next task was looking for correspondence between the combined ontologies. For instance, in the high school gymnasium ontology, we had\u00a0a class ‘GymnasiumEnivaronmentalAspect<\/em>‘. This class had subclasses that represent environmental aspects of\u00a0 a gymnasium. However these aspects can also be applied to\u00a0the rest of the systems. Hence the class was renamed to ‘BuildingEnivaronmentalAspect<\/em>‘. An existing object property ‘hasEnvironmentalAspect<\/em>‘ was used to create relationships between all the systems in the sports complex with the\u00a0\u00a0‘BuildingEnivaronmentalAspect. <\/em>Examples of the new axioms created based on this for all the four systems are the following.<\/p>\n
