In this paper, we present an ontology of educational theories their relation to learning design. This ontology takes into account learning design (LD) specifications such as OUNL-EML and IMS-LD at the conceptual level (1), semantic web standards such as OWL at the formal level (2), as well as JAVA standards at the implementation level (3). This ontology is(More)
Functionality is one of the key concepts of knowledge about artifacts. Functional knowledge shows a part of designer's intention (so-called design rationale), and thus its sharing among engineers plays a crucial role in team-activities in engineering practice. Aiming at promoting engineering knowledge management, we have developed an ontological modeling(More)
Although importance of knowledge sharing among designers has been widely recognized, the knowledge about functionality in the conceptual design phase is hard to capture and is often scattered across technical domains. Aiming at capturing such functional knowledge easily applicable to other domains, we have developed an ontological framework for its(More)
Intelligence in an ITS authoring system could rely on content-based engineering of instructional design (ID) knowledge, i.e. based on principles such as conceptualization, standardization and theory-awareness. An ontology-based architecture with appropriate ontologies has been proposed for a theory-aware ITS authoring system. Ontological engineering (OE) as(More)
Starting from a general characterization of roles, we focus on the ways in which roles are specified, we examine the formal constraints on their definitions, and propose definitional schemas motivating different kinds of roles. This classification , in addition to clarify the notion of role itself, helps us to reconsider the two standard solutions that have(More)
Although a lot of researchers have pointed out the signicance of functional representation, the general relations between function and behavior is not fully understood yet. We consider the knowledge of each component in a system as consisting of two elements. One is a necessary and sucient information for simulation of the component which we call behavior.(More)
