Conceptual indexing of project diagrams in an electronic archive

Abstract

The objective of the research, results of which are present in the article, is the development of a method for conceptual indexing of semistructured project diagrams. The task arouses interest in development of intelligent repositories of design organizations and allows grouping the realized projects. The proposed method of conceptual indexing is based on the use of the special type of ontologies – the project ones. In essence, an ontology plays a role of a compatible model for knowledge representation in a project organization. The ontology includes semantic description of project diagram notations and design pattern used in design activity. Conceptual indexing of project diagrams are carried with the following steps: defining the project context, defining the subset of the electronic archive diagrams corresponding to the project context, defining a degree of conformity of design patterns from an ontology to the project diagram concerning each element of the obtained subset of the electronic archive diagrams. In case of conceptual indexing of project diagrams representing composite elements of information resources of the electronic archive, both a text component (comments in program code, different instructions, etc.) and elements of semistructured notations of project diagrams are taken into account. Technically, the result of conceptual indexing is represented in the form of a fuzzy hypergraph defined on sets of terms of a domain ontology and terms corresponding to design patterns. The ontology of project diagrams describing semantics of UML class diagrams and including «delegation» as a design pattern in Java.
