XML and Semantics

Since the early days of introducing eXtensible Markup Language (XML), owing to its expressive capabilities and flexibilities, it became the defacto standard for representing, storing, and interchanging data on the Web. Such features have made XML one of the building blocks of the Semantic Web. From another viewpoint, since XML documents could be considered from content, structural, and semantic aspects, leveraging their semantics is very useful and applicable in different domains. However, XML does not by itself introduce any built-in mechanisms for governing semantics. For this reason, many studies have been conducted on the representation of semantics within/from XML documents. This paper studies and discusses different aspects of the mentioned topic in the form of an overview with an emphasis on the state of semantics in XML and its presentation methods

Data mediation to message level conflict in heterogeneous web services

Enterprise Information Systems (EISs) are built in isolated and independent environments leading to unpredictable and incompatible structure of data stores. An EI system can expose its functionalities as Web services to share resources of existing global internet infrastructure. The goal of this research paper is to facilitate inter-operation between Web services. Successful and reliable information (message) exchange between Web services is necessary to meet the current challenge of Enterprise Information Integration (EII). A real-\ud world business process, which consists of Web services WS1 and WS2, can be used as a practical scenario for data or message exchange between Web services. In this scenario, message is exchanged by using output of WS1 as input of WS2. If data format of WS1 and WS2 are heterogeneous or incompatible, interoperation between them is impossible if data mediation is not used to resolve message level conflict and incompatibility in the context of syntax and semantics. Data Mediation requires mapping a message from one format to another. We propose to derive a mediation technique that will enable previously less inter-operative heterogeneous Web services to become more inter-operative now. To improve inter-operational performance between Web services our data mediation approach extends and utilizes existing Web service supporting tools WSDL and SAWSDL. (Authors' abstract

Recommendation-based decision support for hazard analysis and risk assessment

Since 2011, automotive companies have to adhere to the functional safety standard ISO 26262. One important safety activity described in the standard is the hazard analysis and risk assessment, which is strongly expert-driven, and therefore expensive, time consuming, and dependent from the individual expert’s opinion. In this paper, we present a decision support system for hazard analyses in order to increase their consistency and efficiency. The system automatically combines results from finished analyses and supporting information in a knowledge base and searches it for useful recommendations during a new hazard analysis and risk assessment

DTD2OWL2: A New Approach for the Transformation of the DTD to OWL

AbstractThe expansion of data sources existed in the web affects on the quality of research information. The correct answer (answer specific) of a request is all depend terms selected for their construction. Such as these terms sometimes mean more sense, the intended meaning may not be found. Fort this need, the Semantic Web has come to cover the semantic level, it proposed an ontological representation of data sources. This representation is implemented by OWL (Web Ontology Language). The current challenge of the Semantic Web is the transformation of data formats exist (SQL, XML ...) to the form of ontology (RDF, OWL ...), in order to facilitate the integration of data sources exist in the semantic web. Our target is to provide a series of extension concepts of DTD2OWL method, a simple and effective method for transforming XML documents into OWL ontologies

Service Orchestration on a Heterogeneous Cloud Federation

During the last years, the cloud computing technology has emerged as a new way to obtain computing resources on demand in a very dynamic fashion and only paying for what you consume. Nowadays, there are several hosting providers which follow this approach, offering resources with different capabilities, prices and SLAs. Therefore, depending on the users' preferences and the application requirements, a resource provider can fit better with them than another one. In this paper, we present an architecture for federating clouds, aggregating resources from different providers, deciding which resources and providers are the best for the users' interests, and coordinating the application deployment in the selected resources giving to the user the impression that a single cloud is used

Dynamic, ecological, accessible and 3D Virtual Worlds-based Libraries using OpenSim and Sloodle along with mobile location and NFC for checking in

This paper proposes the implementation of a 3D virtual library, using open platforms such as OpenSimulator and Sloodle, applied to the integration of virtual learning environments. It also proposes their application to the creation of open libraries to share and disseminate the new dynamic nature of knowledge, in the understanding that 3D virtual worlds may contribute to the future of libraries as part of green initiatives to achieve an ecologic and sustainable planet

Supporting Semantically Enhanced Web Service Discovery for Enterprise Application Integration

The availability of sophisticated Web service discovery mechanisms is an essential prerequisite for increasing the levels of efficiency and automation in EAI. In this chapter, we present an approach for developing service registries building on the UDDI standard and offering semantically-enhanced publication and discovery capabilities in order to overcome some of the known limitations of conventional service registries. The approach aspires to promote efficiency in EAI in a number of ways, but primarily by automating the task of evaluating service integrability on the basis of the input and output messages that are defined in the Web service’s interface. The presented solution combines the use of three technology standards to meet its objectives: OWL-DL, for modelling service characteristics and performing fine-grained service matchmaking via DL reasoning, SAWSDL, for creating semantically annotated descriptions of service interfaces, and UDDI, for storing and retrieving syntactic and semantic information about services and service providers
