Manufacturers of road vehicles have to comply with the functional standard ISO 26262. This standard requires the creation of a safety case, which compiles all the work products of the life-cycle in a traceable manner. The creation of a safety case is extremely time-consuming. Its creation is needed for the purpose of self-assessment in order to manage the liability risk. To speed up such creation,...
The integration of Traditional Chinese Medicine (TCM) and Western Medicine (WM) requires extensive interdisciplinary and cross-cultural collaboration. The productivity of integrated studies is often limited by the lack of understanding between practitioners from different cultural backgrounds. Information technologies, especially the Semantic Web and ontologies, can facilitate the exchange of medical...
Complex networks of direct relevance to biomedicine have not yet been fully mapped largely due to the incompleteness, isolation, and heterogeneity of data. The Semantic Web, by providing a technical framework for the integration and sharing of heterogeneous databases in different domains, can potentially enable more effective complex network mapping and analysis. However, the feasibility of using...
Diabetes mellitus is a group of metabolic disorders characterized by hyperglycemia resulting from defective secretion and / or insulin action. Biological criteria for diagnosis are established and reviewed by an international committee of experts from the American Diabetes Association. A type of diabetes that was little known caused by physiological consequences such pregnancy, gestational diabetes...
The Semantic Web is a collection of components that work together so that a machine is able to process and understand information. In order for this vision to be fully realized, formal standards for representing and interpreting data must be determined and enforced. These formal standards include the Resource Description Framework (RDF) and machine processible ontologies. On the one hand, crafting...
All knowledge representation techniques have to solve the problem of semantics, i.e. how to represent the meaning of the represented knowledge. Basically, there are two possible approaches: explicit and implicit context approaches. Actually, all known knowledge representation techniques are based on the explicit context representation where the meanings of the represented concepts, properties and...
In this paper, we present a new way of delivering social network information about a certain user, solving the intersections that may occur between different accounts that he/she owns and creating a semantic model of the profile in RDF format. The novelty consists in developing a social profile that includes not only personal data and his/her activity in social networks but also information about...
With the increase of information resources and software assets in industries, many companies seek today to improve knowledge sharing and the access to information. In fact, information retrieval has become a daily challenge for many actors of these companies where the quantity of information is huge and is from different sources. The semantic web field tries to address this problem by offering many...
Doctor usually uses his experience from the clinical practice to confirm a diagnosis and to prescribe an appropriate treatment for a specific patient. The computerized medical reasoning should not only focus on existing medical knowledge but also on physician's previous experiences and new knowledge. Such knowledge and experience are vague and define uncertain relationships between facts and diagnosis...
Libraries always play critical role for the dissemination of Knowledge and serve as repositories of knowledge. The revolutionary developments in the Information and Communication Technology had a great impact in the libraries and the Internet has been instrumental in delivering digital information all over the world. The Current Web (web 2.0) is a syntactic and developed based on user centric. The...
Chemical Grid is a collaborative grid platform based on CGSP (China Grid Support Platform) and provides a grid computing environment for various chemical applications. On this platform we constructed a knowledge service architecture using Semantic Web technology, in particular RDF (Resource Description Framework), to integrate heterogeneous chemical information, generate domain knowledge and provide...
At present, the Web resources description methods are mainly used for viewing and retrieving text; these methods are not suitable for exchanging and processing mass information. This article describes a Web resources description model based on RDF which encompasses simple semantic information, with this model Web resources could be handled by computer automatically and the utilization of Web resources...
Modern Web technologies lead to a new virtual reality, where instead of the usual sites and pages Internet user will be provided with structured audio, video or textual information. This information will be generated as a response to the specification of user's needs. The situation requires various Target Web search engines to appear that provide domain-specific interfaces for the obtaining and processing...
Knowledge mobilisation is a transition from the prevailing knowledge management technology to a new methodology and some innovative methods for knowledge representation, formation and development and for knowledge retrieval and distribution. We show that fuzzy ontology will be useful to represent real world knowledge and that approximate reasoning schemes can give us answers which are sufficiently...
In this paper we present a general framework to describe a trace-based learner modelling process. This framework includes three knowledge models: the first model is an explicit representation of observations about learner's interactions with a TEL-system, the second model describes the structure and elements describing the Learner Model and the last model describes the main knowledge elements types...
Traditional agricultural knowledge service is based on keyword rather than content, the recall rate and precision rate cannot to be improved. The knowledge representation based on semantic web can truly achieve the semantic-level knowledge service. This paper analyzes the status of agricultural knowledge service system and points out its shortcomings, elaborates semantic web technologies, studies...
This paper takes knowledge points as key factor in all type of learning process, and any E-learning activity should regard knowledge points as kernel concepts for organizing and extending learning resources. Therefore we suggest the construction of subject knowledge base in E-learning, and provide a universal model to build subject knowledge networks. Besides the purpose to aid E-learning process,...
The ontology language RDFS and OWL are widely used in education semantic web but are limited in their mathematical expressivity. To represent the mathematical knowledge while preserving the semantic, Open Mathematical Document (OMDoc) is used as an ontology language. OMDoc is a content-based markup which focuses on representing the semantic of mathematical formulae instead of the formulae appearance...
The distributed topic maps often need be merged when they are used for knowledge representation, the similarity calculation of two topics is a critical factor which affects the quality of final topic maps directly. In this paper, we present a novel approach to calculate the similarity of topics and merge the distributed topic maps, the method not only implements the syntax comparison between the topics,...
Nowadays home automation systems integrate many devices from security system, heating, ventilation and air conditioning system, lighting system or audio-video systems. Every time a new device is installed, problems with connecting it to other devices and synchronization may appear. The technology trends are to build more powerful and functional new autonomous devices, rather than improve device synchronization,...
