The inherited slots can be specialized by a sub concept. For example, Destruction of Satoyama, a traditional rural landscape in Japan, inherits “a/o place of occurrence = region” from its super concept Destruction of regional environment and specializes it to “a/o place of occurrence = Satoyama.” In this way, RG7112 cost concepts can be defined during the process of ontology building through inheritance and specialization. 2. Basic structure Due to the emphasis on the problem-solving approach of SS, Problem and Countermeasure against a problem are two of the SS ontology’s top-level concepts. Also, when trying to solve a problem,
a goal or goals for countermeasures must be set, and the existing conditions and impacts of the countermeasures must be evaluated explicitly or implicitly. Post evaluation as well as prior evaluation
may result in finding a new problem. Thus, we include Goal and Evaluation in the AZD1390 manufacturer top-level concepts of the ontology. In addition, we set Domain Concept as another top-level concept. In the SS ontology, the knowledge in the domain is not organized by individual Cilengitide molecular weight fields or disciplines, such as energy, climate, population, policy, or laws. Instead, it is organized by more general concepts, such as objects, activities, situations, and attributes, on the basis of ontology engineering theory (Mizoguchi 2003, 2004a, b). In ontology engineering theory, an ontology is composed of domain-specific concepts under the upper level concepts, which are highly domain-neutral. In this way, the ontology is organized in a domain-neutral manner. Our ontology consists of five top-level concepts: Goal, Problem, Countermeasure, Evaluation, and Domain Concept. Although they are SS-specific, they are sufficiently generalized to be independent of the targeted domains. Furthermore, while concrete occurrences and activities can be the sub concepts of Domain Concept, these concepts do not depend on the context of problem-solving.
By describing the world using two types of super concepts, domain-independent and domain-dependent, we can represent any kinds of countermeasures for sustainability Dapagliflozin that we would like to show. Domain-specific knowledge seen from a specific viewpoint can be represented by combining these concepts. Also, such a conceptual system can support the generation of ideas for new concrete countermeasures that were not conceived when the system was initially designed. 3. Prototype of SS ontology Using Hozo as an application platform, we have developed a prototype of SS ontology. It is not our intention in this paper to present a fully developed SS ontology. However, we briefly explain the top-level concepts and second-level concepts with the slots, which are concepts of parts and attributes, that are used to describe them. In the current implementation, SS ontology has 562 concepts and 14 hierarchy levels. (i) Problem (a) Top- and second-level concepts.
