Due to the heterogeneity of the semantic web, the integration of client applications and services using slightly different ontologies is a major challenge, shown by the significant research effort directed towards aligning ontologies and identifying matching concepts. A novel method for service selection by matching a query with services, represented by input and output parameters and a description,...
Data quality is crucial for data integration and the consistency dimension is an important issue in data quality. Traditional methods of data consistency focus on the conflict or inconsistency that occurs in the same concept. However, it is sometimes insufficient to ensure the data consistency only using these methods. In this paper, we divide the conflicts among different data sources into the traditional...
A method for facilitating the communication between agents which have close ontologies by constructing a model of the interlocutor agent ontology is presented. The model of the interlocutor agent understanding is gradually refined based on the information exchanged between agents. We are in the situation where only the terms communicated between agents are made public and known by the other agent...
Based on a geometrical interpretation of knowledge space, this work defines relationships between data, concepts and models, and establishes a framework for their integration. Concepts encapsulate our knowledge and provide a basis for data acquisition. They change as we learn more. Every discipline operates with a specific set of concepts organized in models. In order to co-process data collected...
This paper proposes an easy and natural way to create ontologies through concept mapping. We also present the well-grounded theoretical framework, which supports concept mapping as a valuable educational activity and as a navigational tool
