To streamline and strengthen the process of acquisition, representation and exploitation of scenarii of railroad accidents, it is necessary to harmonize and standardize the terminology used by domain experts. The research aims to significantly improve analytical activities and operations of the various safety studies, by tracking the error in system, hardware, software and human. This paper presents...
Web rapid development has provided new learning environments, bringing online education as a necessity in many sectors of the society. In such an environment, selecting supervisor is a critical decision that graduate students as well as professors are involved with which could benefit from e-learning tools. In this paper we have proposed ADAM, an ADvisor Agent Modeling system, which is a solution...
The Reference Model for an Open Archival Information System has been extraordinarily influential within the digital preservation community. The Preserving Virtual Worlds project explored the application of the OAIS Reference Model for the preservation of computer games, videogames and electronic literature within a research library setting. This paper identifies practical problems in determining the...
In recent years, as the computing and storage technology developed and became affordable, different types of systems including mobile devices such as smartphones become part of our daily life. Personal information is now scattered over different systems and devices in different forms and formats. We utilize the file-level abstraction and file metadata to formulate a solution to personal file management...
Nowadays situation assessment in various scenarios depends on communication networks, information stored in various data stores (information networks), and knowledge of the roles and relations that particular people are involved in (social networks). In order to come up with a high-fidelity situation assessment, information from these three networks must be integrated consistently into a coherent...
Computer games is a form of real-time interactive software wrapped in creatively crafted media that offers game-players engaging, goal-directed play. Designing computer games requires adequate experience and great attention to detail to describe the rules, play and aesthetics that compose the interactive experience. For inexperienced game designers, formalised methods such as game design languages...
This paper describes the development of the srBPA ontology, which is a formal ontology that conceptualizes the elements of the Riva-based business process architecture and the relationships between them. This ontology was instantiated using the UWE's CEMS faculty administration case study in an attempt to assess the correctness and the usefulness of the developed ontology. The assessment revealed...
Web recommendation systems are affected by privacy concerns and legislations. In this paper, we suggested integration between abstract users' preferences and the website semantic structure, which enable us to identify users' power of thinking on specific items. Web personalization systems aim to provide users with what they are looking for on a specific web site. Therefore we collected abstract users'...
Analyze the cases that concepts in ontology are similar, establish a concept similarity computation model based on domain ontology; The computation of concept similarity not only considers the semantic distance between concepts, but also considers the conceptual layer factor and superior concepts coincidence degree, quantizing semantic similarity between concepts nodes in ontology network more comprehensively;...
The semantic gap exists in content-based image retrieval. Many researchers have proposed a variety of methods to bridge or narrow this gap. The methods include into two types: bottom-up and top-down approaches. These approaches have made great progress, but few studies have been done in how to measure it. In this paper, we redefine the semantic gap in a user-centered way and present a method for measuring...
One approach for suiting the diverse and mutable interaction requirements is to tailor interfaces according to the users' preferences or needs. Although literature regarding flexible systems presents results with diverse foci, there has been a lack of works with a sociotechnical view to the problem and which consider methods and techniques to support designers in their practice. This paper presents...
Ontology's significance cannot be denied for realizing the vision of semantic web to add semantics or computer understandable data to the existing human readable web as it enables to structure and conceptualize the shared knowledge of a particular domain on web. But Ontology is abstract and involves various complex issues. This paper presents a framework for such multifarious possible issues of ontology...
With the help of pervasive computing, nowadays it is possible to gather user preference of physical items based on natural interaction, i.e., recognizing and recording user's actual choosing behavior by sensors, then analyzing the history to learn his/her current preference. In this paper, we propose a method based on this idea and implement a prototype to collect and apply the dietary preference...
Currently most present web-based course still organized knowledge in accordance with sections. In view of the existing problems of the above knowledge organization form, this paper takes the curriculum of computer organization as an example to discuss ontology-based knowledge representation. In the extraction of concepts and their relationships, this paper not only borrows ideas from WorldNet, a quite...
Web services have already become one of the most important computing resources and software assets in the Internet. With the large growth in number of Web services and the demand for registries, how to find the required services efficiently or how to gain the best service from the vast service sets become important. By introducing the concept of ontology, a Web service discovery algorithm (WSDA) is...
With the continuous development of computer theories and technologies in the field of education, virtual learning environments (VLEs) are widely used in network-based education because of their features flexibly supporting teaching and learning activities and instructional management. In this paper, based on the study of existing virtual learning environment systems, and taking individualized creation...
In order to solve the problems of geographical information services publication and discovery, technologies of geographical information services publication and discovery based on ontology and description Logic were discussed. OWL-S ontology description model was used to improve semantic lacking in services description. Description logic was introduced as the top way of services matchmaking, and logical...
In this paper, a formal description of knowledge element is given. On the basis of the formal description, a preliminary research about knowledge element acquisition method of emergency management system is proposed. For the characteristics of emergency management knowledge which is multi-field, multidisciplinary, multi-granularity and multi-dimensional, the knowledge element acquisition method is...
Formalization of Ontology is one of the hotspot and difficulty in the study of Ontology. For the order sorted logic can better reflect the different understanding of the natural languge, it is in favor of the formal reasoning of Ontology. So construct an Ontology formalized model using the order sorted logic. It has an important practical significance for the realization of automatic web resources...
With the rapid development of technology and society, academic field tends to be informationization. Electronic information on the Internet attracts more and more attention by the majority of scholars. The article executed systematic study on special text format and language style for Chinese scientific papers , proposed ontology-based classification framework of Chinese scientific papers, constructed...
