Locating termins within a structure

When a terminology is systematically developed for a body of knowledge or a subject domain, a structural ontology is often created which reflects how the concepts in the field relate to each other. 

In Chapter Two we looked at the terms relating to the construction of an assessment. It might be useful to put these terms into a structure, and so this final chapter of Part 2 discusses the relationships between the terms examined more formally, and then summarizes this part of the course.

Different types of relationships can be used in an ontology. In the diagram below, two are used: the whole-part relationship is used to relate the components of an assessment to other components, and the generic-specific relationship is used to relate different instances of the same component to the component itself. The darker the color gets, the more information is contained in the object.
