Firstly, the significance of EMR sharing and interchanging in the Internet environment is introduced. Then, the method to realize multi-source heterogeneous EMR systems' integration and data sharing is proposed with grid middleware technology. To establish the mapping mechanism from ontology to data source, the ontology modeling technology which generates ontology database of medical information is...
News event modeling and tracking in the social web is the task of discovering which news events individuals in social communities are most interested in, how much discussion these events generate and tracking these discussions over time. The task could provide informative summaries on what has happened in the real world, yield important knowledge on what are the most important events from the crowd's...
Important knowledge can be recovered from relational database (RDB) associated with some information system specific domains and converted to semantics. Studying the processes and Methodological Resources (MR) for this conversion has gained relevance in Knowledge Engineering and, particularly, in the Ontology Learning (OL) field. Such MR, organized in an appropriate manner under a methodological strategy,...
Agricultural knowledge is broadly distributed on Internet. They are heterogeneous and polymorphism. In this paper, we gave an overview of using ontology in distributed agricultural knowledge management. We proposed the key steps to implement semantic web to management agricultural knowledge. We discussed semantic knowledge retrieval as emphases application of ontology in agricultural knowledge management...
An Automatic Teaching Materials Construction System based on Mashup is proposed in this paper. The main design concept is to establish a Mashup Data model to obtain the resources on Social Network. Furthermore, using ontology as a rule, the resources are effectively, automatically classified and integrated. The will be able to reduce the digital teaching materials required to spend large amount of...
With the rapid development of Internet technology, web information system has achieved great development, and XML, as the new carrier and standard of information exchanging and calculating on the internet, has been widely used as well. While providing a uniform syntax and semi-structured data model, XML does not express semantics but only structure. This paper combines the web data integration problem...
This research utilized software agent based technology in expanding remote machine tool service system by constructing related remote service ontologies to facilitate its smart and distributive characteristics. These service agents could be used for remote smart machine tool services underlying Internet through the communication protocols supported by both KQML (Knowledge Query Manipulation Language)...
Remote control over the internet is generating significant research interest, of which a major research challenge is the generation of Web User Interface (WUI) according to individual user's specific requirements, for example different users have an interest in monitoring and controlling different machines. Furthermore, the same user may also be interested in different machines in different sessions...
Information integration and interoperability among information sources are related problems that have received significant attention since early days of computer information processing. The objective of Web information integration system is to promote Web information collection, sharing and retrieval in distributed and heterogeneous environment. This paper puts forward an ontology-based approach to...
Ocean Project is aimed to realize an Adaptive and Intelligent Web-Based Educational System (AIWBES) working with traditional learning management systems (LMS). It is designed as a collection of open-source libraries (the Omega Framework), so resulting easily customizable and adaptable to the current e-learning platforms. In this new system each course is presented in different ways according to the...
Data(base) reverse engineering is the process through which the missing technical and/or semantic schemas of a database (or, equivalently, of a set of files) are reconstructed. If carefully performed, this process allows legacy databases to be safely maintained, extended, migrated to modern platforms or merged with other, possibly heterogeneous, databases. Although this process is mostly pertinent...
In this paper we propose a hierarchical data model for representing ontologies. The model is suited for efficiently handling hierarchical relationships, frequently found in the ontology structure. Our hierarchical data model defines a generic representation using hierarchies that can be persisted in a general purpose records structure. We introduce two algorithms that efficiently represent the hierarchical...
Scientific digital libraries serve complex and evolving research communities. Justifications for the development of scientific digital libraries include the desire to preserve science data and the promises of information interconnectedness, correlative science, and system interoperability. Shared ontologies are fundamental to fulfilling these promises. We present a tool framework, a set of principles,...
The Web has been dramatically deepened by the deep Web, which the traditional information fusion system shows disability to integrate. The myriad information hidden behind the deep Web attracts the considerable attention from the researchers. The key element in a deep Web information fusion system is the data source modeling problem, which determine the whole technical method of the whole system....
The Web has become the largest information source, which includes all aspect of human's life. The myriad information is believed to be hidden behind the deep Web, which the search engines and crawlers can't access directly. To extend the human's physical limitation of accessing information, the information fusion system is introduced. The Web is very different from the traditional database community,...
As more and more data is available through the Web, mediation of information from multiple autonomous and heterogeneous data sources becomes a crucial task for future Web information systems. We describe the features of our mediation framework WASSIT (frameWork d'integrAtion de reSSources de donnees par la medIaTion), which provides the user with an integrated view of the underlying data sources....
In this paper Web-community modeling using dataspaces is described. The article considers formal dataspace model and web-communities dataspace conceptual model, that allows information resources interaction (information resources have various data models and various representing and processing methods). A special feature of the dataspaces is that datasources are unknown ahead of time. That's why the...
Based on our proposed semantics-based service-oriented model, we are building a large-scale sensor grid infrastructure that can seamlessly integrate heterogeneous sensor resources from different projects distributed across a wide geographical area. This model has several important features. First, it connects heterogeneous sensor resources via the Internet to automatically collect and aggregate sensor...
The amount of information is exponentially increasing over the Internet where information sources are autonomic, heterogeneous and dynamic. Thus, effective selective dissemination of relevant information is very essential for users. Publish/subscribe systems are gaining increasing popularity due to its loose coupling and scalability. However, traditional content-based pub/sub systems are crisp and...
The explosion of the Internet in recent years has caused the need of the association between different industries and branches to achieve communication and information sharing. However various heterogeneities exist between different data sources, especially semantic heterogeneities because the same data was modeled by different users in different ways. This paper mainly imported the concept of ontology...
