The popularity of service-oriented computing makes more and more services available on the Web. Users make use of these services to achieve their personal goals, such as purchasing movie tickets on-line and booking flights. Existing research has proposed various techniques to assist users to select services for achieving user goals. Typically, user choice of services change under different contexts...
Taking the construction of STKOS (Science and Technology Knowledge Organization System) Service System in Intelligence 3.0 as the mainline, this paper first analyzes various functions that the system shall have, and designs the overall architecture of the system. Second, it introduces the implementation of the system from the perspectives of STKOS registration, triple retrieval, visual presentation...
In the recent past, semantic technologies have played an significant role in service retrieval and service querying. Annotating services semantically enables machines to understand the purpose of services and can further assist in intelligent and precise service retrieval, selection and composition. A key issue in semantically annotating services is the manual nature of service annotation. Manual...
Semantic annotation plays an important role for semantic-aware web service discovery, recommendation and composition. In recent years, many approaches and tools have emerged to assist in semantic annotation creation and analysis. However, the Quality of Semantic Annotation (QoSA) is largely overlooked despite of its significant impact on the effectiveness of semantic-aware solutions. Moreover, improving...
Web services are widely used for enterprise software development. Web service protocols simplify application integration thanks to interface description that can be processed at runtime and, in addition, due to mature and widely used standards for transportation and internetworking. Implementation of service-oriented architecture starts to get acceptance in the field of industrial automation ranging...
Mobile devices are used extensively by the people for communication, music, entertainment, Internet and social networking. There is a lack of applications, which can be really useful for the professionals to improve their working capabilities. Though mobile phones are used by people living in rural areas, but there are hardly any relevant applications for them to improve their productivity. In this...
An extension of the HTN-DL web service model is presented, including rules for web service behavior and compliance validation against customer requests. The intention is to overcome the limitations of HTN-DL and OWL-S in covering business constraints in service selection and also the limitation of preconditions. The proposed approach validates a web service obtained through HTN-DL planning, for compliance...
This paper gives an overview of the work done to develop a task ontology based on the task templates provided by CommonKADS. It discusses how modeling of KBS is done in the CommonKADS and also gives a brief overview of OWL-S which an upper-level ontology for web services. Constructs of OWL-S ontology have been compared with constructs proposed by CommonKADS to see to what extent it can be reused to...
In many scientific disciplines, and in biomedicine in particular, researchers rely on ontologies to enable them to annotate and integrate their data. These ontologies are living and constantly evolving artifacts and the ontology authors must rely on their user community to ensure that the coverage of the ontologies is sufficient for annotations and other tasks for which users deploy the ontologies.
The number of electronic devices found in home environments is increasing, leading to an increase in the energy consumption in users' premises. Introducing a Home Energy Management System (HEMS) into user residences might provide the necessary tools to reduce and optimize the energy consumption in home environments. However, this is not an easy task as devices can use different communication technologies...
Ontology Model and Semantic Link Network (SLN) are two important semantic data models in Semantic Web. Ontology Model can describe network resource in concept space, while SLN can describe various links and relations between network resources. Combination of Ontology Model and SLN can help to improve the effect of network resource retrieval, but data transfer and exchange between ontological knowledge...
Recently semantic technology have been popular in the spatial information area, but this semantic ability can only support for its own system, cannot fulfils other system's need. So a semantic service middleware taking place of original semantic system, will give a free semantic service without change the system's internal structure.
We present an approach to improve design-time user support during the composition of web services into BPEL processes. The approach is based on adding semantic service descriptions to SimpleBPEL, a framework that supports web service novices in designing workflows. Experienced BPEL developers define domain specific profiles, containing parts of a BPEL process called SimpleBPEL fragments. The application...
Services for mobile devices are gradually growing with more orientation towards user-location oriented services. Mobile users nowadays are no longer satisfied with the old frameworks that render static and inappropriate services with regardless to user's location. They require a service that provides intelligent suggestions and results that pertain to their locations, which are also of maximum usefulness...
Web Services Description Language (WSDL) allows a structured way to standardize the description of Web Services, exploiting XML for the exchange of structured information. Nevertheless XML supports little interoperability between services, expected when WSDL documents have to be combined. In this context, the Semantic Web has become a promising research field. Semantic Models (e.g. RDF or OWL) allow...
To develop the Practice Teaching System of Information Management Training (PTSIMT), this paper presents the method based on agent and Ontology to design the architecture, which consists of four layers with different functions. The Agency is in charge of giving support to the PTSIMT processes, which has three types. In this method, Ontology is used to represent the knowledge in knowledge base and...
This paper focuses on RDF and ontology and semantic-enable geo-spatial services discovery. The domain ontology DB of reservoir area application was firstly proposed; based on this domain ontology DB, semantic information are annotated to the profile of the services to be discovered; and OWL-based service description language OWL-S instead of WSD are used to provide service description. Based on Oracle...
Intelligence of present e-Learning systems is usually static: these systems may provide learning materials of different complexity and/or in differing sequence to various learners according to their abilities, skills and learning progress, but these systems hardly themselves have the ability to evolve and learn new knowledge during their life-cycle. We consider intelligence, which is characterized...
This paper introduces connectionistic concept grid (CCG), which is used for representation and reasoning of engineering knowledge applied for the industrial systems. The paper also presents the Crossword tool which was used for computer aided modelling and execution of CCG. CCG is able to provide semantic descriptions of objects and processes and was developed to overcome limitations of earlier knowledge...
Web services over the Internet are widely used nowadays. Controlling access in Web services environment is crucial and a significant challenge because this environment is more dynamic and heterogeneous. Compared with the existing models, attribute-based access control is more appropriate for Web services, but it do not fully exploit the semantic power and reasoning capabilities of emerging web applications...
