Ontology reuse for multiagent system development through pattern classification

Abstract

Summary Ontologies play a crucial role in multiagent systems (MASs) development, especially for domain knowledge modeling, interaction specifications, and behavioral aspect representation. Domain‐specific ontologies can be developed in an ad hoc or systematic manner through the incorporation of ontology development steps on the basis of agent‐oriented methodologies. Developing such ontologies, however, is challenging because of the extensive amounts of knowledge and experience required. Moreover, since many ontologies cater for very specific domains, the question arises of whether some can be reused for faster systems development. This paper attempts to answer this question by proposing an ontology pattern classification scheme to allow the reuse of existing ontology knowledge for MAS development. Specifically, ontology patterns relevant to the design problem at hand are identified through the pattern classification scheme. These patterns are then reused and shared among agent software communities during the system development phase. The effectiveness of the proposed approach is validated using a restaurant‐finder MAS case study. Our findings suggest that utilization of the classified ontology patterns reduces development time and complexity when dealing with domain‐specific applications. The scheme also seems useful for software practitioners, where searching and reusing the patterns can easily be done during the analysis, design, and implementation of MAS development.

Ontology for Architectural Knowledge Condensation in a Co-Localized Agile Environment

“…Одним из способов повторного использования архитектурного знания является применение онтологий, которые представляют собой формальное описание связанных друг с другом обобщенных понятий [47]. Онтология позволяет повторно использовать знания путем прояснения неоднозначностей [26] и способна облегчить процесс конденсации знаний, поскольку вводит словарь для обмена информацией и помогает принимать более конкретные архитектурные решения [48].…”

Ontology for knowledge condensation to support expertise location in the code phase during software development process

“…Moreover, in addition, to help with the decision making, ontologies could mitigate the problems caused by the knowledge vaporisation mentioned before, and also could prevent constant questions to experts which sometimes lead to an erosion in interpersonal relationships, affecting the knowledge flow. Additionally, ontologies present a visual way to share a common understanding of an information structure between several people or computer systems [24], and also they allow to reuse knowledge through ambiguities clarification [25].…”

RTPO: A Domain Knowledge Base for Robot Task Planning

“…It can represent and understand the sophisticated world. Until now, it has been widely employed in various fields such as AI [4,5], Semantic Web [6,7], Information Science [8], etc. Ontology-based task planning is essentially a series of relevant queries and reasoning on ontology knowledge [9].…”
