It has become an era where everything is on the web with ever more chances of data utilization on the web. Still, there are obstacles to make the use of the web efficiently. With too much information, Internet users have often come across information that are not relevant for their use. On top of that, until recently, most of web content have not contained semantic information, posing difficulties...
The emerging growth and evolution of web based systems and services make the job of audit professionals a complicated and time-consuming one for many enterprises. In this context, continuous process auditing (CPA) systems in the form of audit-as-a-service (AaaS) emerges as an inexpensive and effective approach. A CPA system helps to satisfy process auditing needs and recommendations in the context...
In health informatics there is no such mechanism of binding healthcare service providers and requesters that provide publish and retrieval of healthcare services. Healthcare web services should be published with formalized semantic descriptions in a structured and uniform way, to automate healthcare service discovery. The use of semantic web technologies and service oriented computing for efficient...
In this paper we mine over 80 million twitter micro logs in order to explore whether data from this social media initiative can be used to identify sentiment about tourism and Thailand amid the unrest in that country during the early part of 2010 and further whether analysis of tweets can be used to discern the effect of that unrest on Phuket's tourism environment. It is proposed that this analysis...
This paper provides basic ideas and methods toward SWS based business services composition. First, a formal model of business services composition was introduced. Second, an approach to service set mining for service composition was presented, and finally, the paper presents the solution model of requirement driven service selection.
Semantic Web services have been employed in a wide range of applications and have become a key technology in developing business operations on the Web. However, heterogeneity is a major problem of the current semantic Web service technologies. In particular, semantic Web services described by different description languages cannot work together. For example, a Web service described by OWL-S cannot...
The performance of automatic Web service composition in massive service candidate collection behaves badly when running inappropriate strategy on whole candidate collection. A new service composition model is proposed to solve this problem. The model formally describes Web service via ontology technique, which can easily get the user's demand. The paper first defines the cost to satisfy user's requirement,...
We describe a model-driven translation approach between semantic Web service based business process models in the context of the SUPER project. In SUPER we provide a set of business process ontologies for enabling access to the business process space inside the organisation at the semantic level. One major task in this context is to handle the translations between the provided ontologies in order...
In this paper, we present a framework to facilitate reputation-based service selection with reputation management, which has three key features. First, we use a structured overlay network as the decentralized service repository system for improved efficiency. Second, we propose an adaptive QoS-aware service discovery approach. Then, we present a service-oriented distributed reputation assessment algorithm...
Semantic business processes require new analysis techniques able to deal with behavioral properties that also consider semantic aspects. In this paper, a model checking method is introduced including semantic aspects in both the model description and the formula to be verified. Finally a prototype of the model checker based on the use of RDF and SPARQL tools is also described.
Relation annotation (RA) is a process of marking up relations among a set of entities identified from a plain text. RA is important to enterprise applications due to its capability of revealing semantics in business environments. However, RA in business environment is different from that in news domain because the entities involved in the relations in business domain often not just refer to entities...
Composite services are often long-running, loosely coupled, and cross-platform, so they bring additional complexity to the system in the presence of failures. Transaction is a basic concept in building reliable distributed system. However, Web transaction cannot be easily rolled back as conventional ACID transactions, so a main problem that remains is how to cancel a long-running Web transaction....
The Internet as we know it today is in an extending success: more than 1.3 billions people are connected to the Web across the globe and more than 700 EB of informations were created or replicated world wide. The development is driven by users, as well as by technology. Web 2.0 changed users to creators of content. Intelligent devices, clothes, fridges, machines and factories are connected and interact...
Data warehouse (DWH) systems play an important role in the IT landscapes of today's enterprises. In order to cope with the complex transformation processes and big data volumes, they have to be supplemented by metadata. Two main uses of such metadata are data lineage analyses, allowing data elements within the DWH to be traced back to their origin, and impact analyses, revealing which other elements...
This paper proposes a new method for the automatic composition of semantic Web services. The proposed method consists in constructing a graph and then searching for a sub-graph of this graph, which will represent a candidate composition solution. First, the method constructs a directed acyclic graph, which represents the functional semantics of the Web services as well as the semantic dependency between...
The appearance of semantic Web makes the automatic discovery and invocation of geospatial Web services become possible. The key technology of automatic discovery is service matching. This paper designs a common semantic service description model, which contains four aspects as the classification of service, input/output, precondition/effect and the quality of service (QoS), to describe the geospatial...
The Semantic Web is a project and vision of the World Wide Web Consortium to extend the current Web, so that information is given well-defined meaning and structure, enhancing computers and people to work in cooperation. Semantic technologies are being added to enterprise solutions to accommodate new techniques for discovering relationships across different database, business applications and Web...
Problem in geography information application integration is analyzed, concept and framework are discussed. Geography information integration framework focused on business is put forward, application organized for user's point of view, user requirement will transfer to scenario with semantic information, element of scenario will bind to service with semantic Web method, scenario will transfer to application...
According to recent surveys, information workers send and receive an average of 133 messages per day, and users talk about "living" in email, spending an average of 21 percent of their time on it, as well as reporting general problems with overload. Information created by a business can represent either an asset or a liability, depending largely on how well it is managed. Email is no different...
Traditional Websites no longer meet the needs of todaypsilas software agents because of their unstructured nature in terms of the semantics they convey. One of the primary objectives of semantic Web is to enable software agents infer facts and knowledge out of different Websites. The primary aim of this project is to develop an application to manipulate OWL files, browse ontologies and enable software...
