Calculation of weight of entities in ontologies is valuable as it facilitates the searching, ranking, conflicts solving and elements removing problem of ontologies. Current weight calculation methods just consider the structure properties of ontology. We argue that weight of entities in ontology should be changed along with the using of ontology, similar with human's knowledge. In this paper, we propose...
Nowadays, with rapid popularization and development of the Internet, Semantic web plays a more important role in the design of information system. But in the construction of teaching resource library, there seldom involve in this technology. So this paper proposes a design and development framework for teaching resource library system that uses semantic web technology. The use of semantic web can...
In the domain of intelligent collaboration, the application of semantic information is a prospective research field. The collaboration system of the forthcoming generation is expected to consist of semantic services of applications as well as semantic human-machine interpretation. In this paper, a simple example of such a system is introduced. Based on this example system, the operation of semantic...
We propose a novel T-commerce model based on semantic interaction, as the TV broadcasting environment is moving to interactive digital TV such as IPTV, Hybrid TV, and Smart TV. The purpose of our work is to design and implement the system of our new T-commerce model. Thus, our system applies spatial relation rules and ontology for object recognition if a viewer is interested in one on the screen of...
With the advent of social networks and tagging systems, The Internet has recently witnessed a big leap in the use of Web Recommendation Systems WRS. Based on users' likings of items and their browsing history on the world wide web, these systems are able to predict and recommend items and future purchases to users. They are being used now in various domains, like news article recommendation, product...
The proliferation of ontologies and taxonomies in many domains increasingly demands the integration of multiple such ontologies to provide a unified view on them. We demonstrate a new automatic approach to merge large taxonomies such as product catalogs or web directories. Our approach is based on an equivalence matching between a source and target taxonomy to merge them. It is target-driven, i.e...
The project in question is a project of the Semantic Web and Knowledge Management. The goal is to realize a web interface for semantic search of English exercises, in according to criteria (like content, difficulty level, type, number of entries and so on), assuming that online there are many sites that offer English language exercises. Using Web Semantic Tools (Ontologies, Annotations), it will be...
Personalized information retrieval and recommendation systems have been proposed to deliver the right information to users with different interests. However, most of previous systems are using keyword frequencies as the main factor for personalization, and as a result, they could not analyze semantic relations between words. Also, previous methods often fail to provide the documents that are related...
The computation of semantic similarity of terminologies in gene ontology is an important application of gene ontology. Moreover, it is an important approach for biologists to deal with the semantic heterogeneity of biological data sets. Existing approaches in this field are based on semantic distance or information quantity. The author proposes a comprehensive approach where the similarity is first...
This paper introduces the shortage of the multimedia search of IETM and analyzes the limitations of the MPEG-7 standard based on XML Schema language on the multimedia contents representation of IETM. With MPEG-7 standard, this paper explores the reality construction of OWL (Ontology Web Language) of IETM multimedia, which contains: the OWL representation of the describing symbol of IETM low level...
Electronic Patient Records (EPR) systems are developed proprietarily and often only serve one specific requirement within a healthcare institute. Heterogeneous EPR platforms introduce a problem in cross-system patient information exchange due to the lack of a uniform system and an accepted standard. This makes it very difficult for clinicians to capture the complete clinical history of a patient that...
Semantic interoperability problems have found their solutions using languages and techniques from the Semantic Web. The proliferation of ontologies and meta-information has improved the understanding of information and the relevance of search engine responses. However, the construction of semantic graphs is a source of numerous errors of interpretation or modeling and scalability remains a major problem...
Semantic focused crawler computes the priority of pages crawling by web page semantic similarity with topic which is defined by ontology. Ontology is a new approach referred to as the main pivot of change from the present web to a new web called semantic web. The main problem about focused crawlers is to find a computation function of appropriate relevance based on which the crawler can estimate the...
Publish subscribe systems have received considerable attention during recent years. XML based publish-subscribe systems are on tremendous rise because of the properties of XML. But in order to accomplish the task filtering mechanism is required. Many filtering mechanisms exists such as XFilter, YFilter, AFilter etc, but most of these mechanisms do not filter the document for semantic matched information...
In model-based diagnostic algorithms, it is assumed that the model is correct. If the model is incorrect, the diagnostic algorithm may diagnose the wrong fault, which can be costly and time consuming. Using past maintenance events, one should be able to make corrections to the model in order for diagnostic algorithm to correctly diagnosis faults. In this paper, a maturation approach is proposed which...
With the introduction of the SAWSDL W3C recommendation, the possibility of enriching web service interfaces with semantic model references surfaced as a foundation for semantic web services. However, the recommendation says neither what the semantic model should be nor what to do with the actual XML data. In this paper, we exploit our conceptual model for XML data to generate SAWSDL enriched XML schemas,...
The heterogeneity of ontologies is a major obstacle to the promised interoperability of knowledge in the Semantic Web. Ontology mappings can help to mitigate the effects by specifying the correspondences between related ontologies. However, the creation of mappings is still complex and time-consuming and therefore it is appealing to discover existing mappings and to reuse them. For reuse, it is essential...
In spite of the fact that many of the proposed context awareness frameworks allow scalability and dynamic interaction with heterogeneous devices disseminated in the environment, very often they are not able to fully profit from the semantic technology to supervise and manage the environment. Indeed, using ontologies allows us to integrate information coming from heterogeneous sources and to share...
The exponentially increasing cyber threats with the expansion of web applications have become the biggest security concern for e-business and information sharing communities. Current survey shows that application layer is more prone to web attacks. Recent survey carried out by Nation Vulnerability Database shows that, on average 15 new vulnerabilities are released per day, thus proved that existing...
In order to improve users ability to interact with devices in an intelligent house, we propose a platform for intelligent device composition, based on Service Oriented Architecture. In such an environment, devices can be controlled and monitored using Service invocations, or they can interoperate in order to fulfil complex tasks, using Service composition. As part of our platform, we define a language...
