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)
Intelligence sponsored the first Knowledge Acquistion for Knowledge-Based Systems Workshop (KAW) in order to increase the limited communication between knowledge acquisition researchers and help reduce the substantial duplication of their efforts. Organized by John Boose and Brian Gaines, this workshop was held from November 3-7, 1986 in Banff, Canada.(More)
This paper discusses long-term prospects of AI-ED research with the aim of giving a clear view of what we need for further promotion of the research from both the AI and ED points of view. An analysis of the current status of AI-ED research is done in the light of intelligence, conceptualization, standardization and theory-awareness. Following this, an(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)
In Sustainability Science (SS) it is not only difficult to identify what needs to be solved but how to solve the problems once identified. There has been no consensus on underlying question of " What is structuring in SS? " This paper focuses on articulating in the form of a reference model a set of required elements, functions, and actions for structuring(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)
We have developed an environment for building/using ontologies, named Hozo, based on both of a fundamental consideration of an ontological theory and a methodology of building an ontology. Since Hozo is based on an ontological theory of a role-concept, it can distinguish concepts dependent on particular contexts from so-called basic concepts and contribute(More)
