Introduction: Autism is a nervous system disorder, and since there is no direct diagnosis for it, data mining can help diagnose the disease. Ontology as a backbone of the semantic web, a knowledge database with shareability and reusability, can be a confirmation of the correctness of disease diagnosis systems. This study aimed to provide a system for diagnosing autistic children with a combinat...
While ontology development is beneficial, it is very costly and time consuming. In order to reduce this cost as well as to increase the accuracy and quality of ontology development, researchers have proposed different methodologies. The goal of these methodologies is to present a systematic manual or semi-automated development of ontologies, while each differs and has its strengths and weakness...
the present paper aims at clarifying the role of the concept “walåyah” in the philosophy of the unity of being in islamic philosophy (waedat al-wujid). the concept “walåyah” is deeply built into the philosophic system of the islamic theory of being, and moreover the dynamic aspect of this concept has always activated islamic philosophy of existence and stimulated the thought of islamic philosop...

information systems (is) and the process of distinguishing information systems ontology have been the center of challenge during the 50 years of is development. the importance of this challenge is emergent in direct link between knowledge development process in is and the is ontology. in other words, theorizing and efforts to falsify theories, which have been developed, is influenced by the way...
Context-aware systems must be interoperable and work across different platforms at any time and in any place. Context data collected from wireless body area networks (WBAN) may be heterogeneous and imperfect, which makes their design and implementation difficult. In this research, we introduce a model which takes the dynamic nature of a context-aware system into consideration. This model is con...
Ontology is the main infrastructure of the Semantic Web which provides facilities for integration, searching and sharing of information on the web. Development of ontologies as the basis of semantic web and their heterogeneities have led to the existence of ontology matching. By emerging large-scale ontologies in real domain, the ontology matching systems faced with some problem like memory con...
In recent years, many efforts have been done to design ontology learning methods and automate ontology construction process. The ontology construction process is a time-consuming and costly procedure for almost all domains/applications, so automating this process is a solution to overcome the knowledge acquisition bottleneck in information systems and reduce the construction cost. In this artic...
