Analysis of the performance of languages for working with the ontological model of the assembly of 3D-constructions

Abstract

Abstract The paper studies the performance of various languages used to work with ontological models. The languages are used in the methodology for modifying and verifying the 3D construction ontology presented in this paper. The methodology consists of three stages: building an ontological model of the assembly system and an ontological model of the desired 3D structure, modifying the original 3D structure model, and verifying the result in order to decide on further actions. The paper considers two groups of languages: query languages and modification languages. SQWRL and SPARQL are analyzed as query languages, and OWL DL and SWRL are used as modification languages. The comparison is based on the speed of performing such basic Boolean operations as conjunction and disjunction. To achieve the greatest objectivity a study is carried out on models of different dimensions. All measurements are made in the Protégé system since this system supports all 4 languages, the dependence of the runtime results on the runtime environment is minimized. The evaluation results are presented as a graph of the dependence of the rate of change in the process of performing an operation on the number of elements in the ontological model. The conclusion shows that the languages OWL DL (reasoner Pellet) and SWRL as ontology transformation languages and SPARQL as a query language are most suitable for working with the assembly ontology of 3D structures.
