“…27 The hybrid distributed software architecture has been applied to other domains such as grid information services in previous studies. [28][29][30] In this study, we focus on applying facade software design pattern to achieve a hybrid architecture to detect copyright violations. XML based metadata standards have been studied to define both services and data in various domains.…”

Summary In recent years, the credibility of information on social networks has attracted considerable of interest due to its critical role in the spread of information online. In this paper, we argue that the quality of information created on social networks can be analyzed using its provenance data. In particular, we propose an algorithm that assesses information credibility on social networks in order to detect fake or malicious information using a fuzzy analytic hierarchy process to assign proper weights to the proposed metrics. In order to test the usability of the proposed algorithm, we introduce a prototype implementation and test it on a large‐scale synthetic social provenance dataset. The initial results reveal a proportional relationship between our proposed distance from positivity algorithm and the provenance graph metrics‐based user credibility.

“…We designed and built a novel architecture 63 for a WS‐Context complaint metadata catalog service supporting distributed or central paradigms. The main intended use of our approach is to support information in dynamically assembled Grids where services are tied together in a dynamic workflow to solve a particular problem.…”

We discuss the development and application of Web-service-based geographical information system (GIS) Grids. Following the WS-I+ approach of building Grids on Web service standards, we have developed data Grid components for archival and real-time data, map generating services that can be used to build user interfaces, information services for storing both stateless and stateful metadata, and service orchestration and management tools. Our goal is to support dynamically assembled Grid service collections that combine both GIS services with more traditional Grid capabilities such as file transfer and remote code execution. We are applying these tools to problems in earthquake modeling and forecasting, but we are attempting to build general purpose tools by using and extending appropriate standards.

“…To achieve federation, the Hybrid Service is designed to support information integration technique in which metadata from several heterogeneous sources are transferred into a global schema and queried with a uniform query interface. To manage both quasi-static and dynamic metadata and provide interoperability with wide-range of Web Service applications, the Hybrid Service is integrated with two widely-used, WS-I compatible Web Service Specifications: UDDI and WS-Context and their implementations: Extended UDDI XML Metadata Service [25] and WS-Context XML Metadata Service [26].…”

Abstract-Independent Grid projects have developed their own solutions to Information Services. These solutions are not interoperable with each other, target vastly different systems and address diverse sets of requirements. To address these challenges, we designed a novel architecture for a Grid Information Service that provides unification, federation and interoperability of major grid information services. The proposed approach forms an add-on information system that interacts with the local information services and assembles their metadata instances. We introduce a prototype implementation and present its evaluation. The results indicate that the proposed approach achieves unification and federation of custom implementations of grid information services with negligible processing overheads.
