An ontology-based universal design knowledge support system

Abstract

Cataloged from PDF version of article.An effective and efficient knowledge support system is crucial for universal design process, as it has become a major design issue in the last decade with the growth of the elderly population and disabled people. There are a limited number of CAD investigations on the nature of knowledge processing that supports the cognitive activities of universal design process. Therefore, this paper proposes an ontology-based computer-assisted universal design (CAUD) plug-in tool that supports designers in developing satisfactory universal design solutions in the conceptual design phase. The required knowledge processing and representation of the developed tool is motivated by the ontological language. It is based on the multiple divergence-convergence cognitive strategies and cognitive needs of designers in the analysis/synthesis/evaluation operations. The CAUD plug-in tool is the first attempt to interface the universal design knowledge ontologically and respond to the requirements of conceptual design phase. According to the user acceptance study, the tool is assessed as useful, understandable, efficient, supportive and satisfactory

Grammatical error simulation for computer-assisted language learning

“…However, designing effective tutoring strategies from learners' data requires numerous language learners with a variety of cognitive and affective factors (e.g., proficiency level, age, gender, mood, and concentration) [8], which is usually very expensive and timeconsuming even with design support systems [1].…”

Setting The Key Issues And A Prioritization Strategy For Designing Sustainable Interior Environments

“…Although there is a general lack of knowledge how designers achieve solutions, they should operate an effective strategy to increase the possibility of creating promising concepts as early as possible (Afacan and Demirkan, 2011). Analyzing interior environmental quality raises a number of methodological difficulties involving correlated qualitative and quantitative variables.…”

“…Using a grid box, the technique of cross consistency assessment (CCA) reduces the number of possible solutions by eliminating illogical solution combinations (Afacan and Demirkan, 2011;Ritchey, 2006). This method is based on the insight that there may be numerous pairs of conditions in the morphological field that are mutually incompatible.…”

A novel method for adaptive knowledge map construction in the aircraft development

“…To express the semantic information of knowledge to ensure that the knowledge is comprehensible to either humans or machines [1,3], domain ontology is constructed to annotate the knowledge to specify the knowledge domain. The complexity of the ontology model will increase dramatically with the increase of covering areas.…”
