A State-of-the-Art Survey on Semantic Web Mining  [PDF]
Qudamah K. Quboa, Mohamad Saraee
Intelligent Information Management (IIM) , 2013, DOI: 10.4236/iim.2013.51002
Abstract: The integration of the two fast-developing scientific research areas Semantic Web and Web Mining is known as Semantic Web Mining. The huge increase in the amount of Semantic Web data became a perfect target for many researchers to apply Data Mining techniques on it. This paper gives a detailed state-of-the-art survey of on-going research in this new area. It shows the positive effects of Semantic Web Mining, the obstacles faced by researchers and propose number of approaches to deal with the very complex and heterogeneous information and knowledge which are produced by the technologies of Semantic Web.
Web Semantic and Ontology  [PDF]
Elodie Marie Gontier
Advances in Internet of Things (AIT) , 2015, DOI: 10.4236/ait.2015.52003
Abstract: Ontologies have become a popular research topic in many communities. In fact, ontology is a main component of this research; therefore, the definition, structure and the main operations and applications of ontology are provided. Web content consists mainly of distributed hypertext and hypermedia, and is accessed via a combination of keyword based search and link navigation. Hence, the ontology can provide a common vocabulary, and a grammar for publishing data, and can supply a semantic description of data which can be used to preserve the ontologies and keep them ready for inference. This paper provides basic concepts of semantic web, and defines the structure and the main applications of ontology.
SEMANTIC WEB SERVICE COMPOSITION APPROACHES: OVERVIEW AND LIMITATIONS
Furkh Zeshan,Radziah Mohamad
International Journal of New Computer Architectures and their Applications , 2011,
Abstract: Service composition is gaining popularity because the composite service presents the features that an individual service cannot present. There are multiple web services available over the web for different tasks. Semantic web is the advance form of the current web, where all the contents have well defined meanings, due to this nature; semantic web enables the automated processing of web contents by machines. At run time, the composition of these services based on the requestera€ s functional and non-functional requirements is a difficult task due to the heterogeneous nature of results of the services. This paper introduced some requirements that when fulfilled, a successful composition process can be achieved. In order to find the best approach, various composition approaches on these requirements were evaluated. Suggestions were provided on what approach can be used in which scenario in order to gain the best results.
Applications of Norm and Situation Calculus in the Semantic Web Service Composition  [PDF]
Jun Zhao, Xiaozhu Gu
Journal of Software Engineering and Applications (JSEA) , 2010, DOI: 10.4236/jsea.2010.38090
Abstract: Semantic Web service studies are carried out around the OWL-S, however, OWL-S model does not contain the descrip-tion of preferences and constraints when we choose and use them in different organizations, different cultures, different sectors and actors because of OWL capacity limitations in rules. It means that Semantic Web service composition can not compose users’ subjective services from the user requirements. The paper makes up for the semantic shortcoming of OWL-S through using norm semantic scalability, and achieves the formal description of the norm by using the situation calculus. Finally, the paper also takes a tourism composite service as an example how to extend the ability of the semantic description of OWL-S, which shows us the combination of the norm and the situation calculus. It is positive significance for eventually realizing semantic extension of OWL-S.
A Proposal of an E-Learning Inter-Operable Platform Based on Semantic Web  [PDF]
Jimmy Rosales Huamani, José Castillo Sequera, José Miguel Ca?amero, Fabricio Puente Mansilla, Gustavo Boza Quispe
Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.68076
Abstract: Electronic learning, commonly called e-learning, has the goal of using technology to spread knowledge. Actually, the fast growing of Internet has allowed the creation of a variety of e-learning platforms. Thus there is the need for the regulation and interoperation of these platforms. Interoperability is a key factor in e-learning systems because it allows exchange and reuse of educational resources developed in different platforms. Problems may appear in their design and implementation because of the lack of interoperability among educative platforms contents. For that reason, it is important to use meaningful information to make possible the interoperability among different environments and to help in the management of proper contents. This is the area where Semantic Web may play a key role for reaching this goal. In this work, we propose the design of an e-learning platform prototype, that using semantic meaning, helps in the solution of interoperability problems.
A Prototype of a Semantic Platform with a Speech Recognition System for Visual Impaired People  [PDF]
Jimmy Rosales-Huamaní, José Castillo-Sequera, Fabricio Puente-Mansilla, Gustavo Boza-Quispe
Journal of Intelligent Learning Systems and Applications (JILSA) , 2015, DOI: 10.4236/jilsa.2015.74008
Abstract: In the world, 10% of the world population suffer with some type of disability, however the fast technological development can originate some barriers that these people have to face if they want to access to technology. This is particularly true in the case of visually impaired users, as they require special assistance when they use any computer system and also depend on the audio for navigation tasks. Therefore, this paper is focused on making a prototype of a semantic platform with web accessibility for blind people. We propose a method to interaction with user through voice commands, allowing the direct communication with the platform. The proposed platform will be implemented using Semantic Web tools, because we intend to facilitate the search and retrieval of information in a more efficient way and offer a personalized learning. Also, Google APIs (STT (Speech to Text) and TTS (Text to Speech)) and Raspberry Pi board will be integrated in a speech recognition module.
UMIS: A Service for User Model Interoperability  [PDF]
Federica Cena, Roberto Furnari
Advances in Internet of Things (AIT) , 2012, DOI: 10.4236/ait.2012.24012
Abstract: In this paper we describe UMIS, a service architecture that enables user adaptive applications to exchange User Model data on the Web. UMIS provides a set of facilities that allow applications to interoperate with minimum changes in their internal logics and knowledge representation. The goal is to support the process of interoperability in three ways: providing an efficient centralized discovery service; offering a service for simple interaction for the exchange of UM value in a p2p way; and offering a negotiation mechanism to be used in case of communication hurdles (i.e. semantic ambiguities and missing response). We developed a proof-of-concept prototype of UMIS and we tested it with an existing user-adaptive application. According to our test results, our approach improves the communication with respect to standard solutions for interoperability regarding the quality of exchange, with a negligible impact on the communication costs and traffic generation.
Web Semantica: ontologias como ferramentas de representa??o do conhecimento
Pickler, Maria Elisa Valentim;
Perspectivas em Ciência da Informa??o , 2007, DOI: 10.1590/S1413-99362007000100006
Abstract: the semantic web is an extension of the web that adds semantics to the current format of data representation. for this, several technologies were proposed, among them the creation of ontologies, aiming at attributing sense and meaning to the content of documents, acting as tool for knowledge representation. in the present research, it was attempted to verify whether the ontologies would be used only to represent the subject of a web page through terms in context or rather, they would try to control the vocabulary of the web as a thesaurus.
