COTS GIS Integration and its Soap-Based Web Services

In the modern geographic information systems, COTS software has been playing a major role. However, deploying heterogeneous GIS software has the tendency to form fragmented data sets and to cause inconsistency. To accomplish data consolidation, we must achieve interoperability between different GIS tools. In my thesis project, I developed Vector and Raster Data Adapters to implement the spatial data consolidation. I deployed ArcIMS to publish the spatial data and metadata onto Internet. Furthermore, the SOAP-Based GIS Web services are implemented to achieve the enterprise information system integration. The contribution of ours in this project is we have streamlined the COTS GIS server, the J2EE coordinator server, the web service provider components, and the COTS web publishing tools into a hybrid web service architecture, in which the enterprise information system integration, the web publishing, and the business-to business online services are uniformed

Performance measurements of Web services

Web services are rapidly evolving application-integration technologies that allow applications in heterogeneous environments to communicate with each other. In this thesis we perform a measurements-based study of an e-commerce application that uses web services to execute business operations. We use the TPC-W specification to generate a session-based workload. The component level response times and the hardware resource usage on the different machines are measured. The component level response times are extracted from the application server logs. From the results it is seen that as the workload increases the response times of the web services components increase. From the hardware resource usage it is clear that web service components require more processing time due to the processing of XML data required in each web service call. The method used in this thesis allows us to study the impact that different components can have on the overall performance of an application

Integrasi Sistem Informasi Laboratorium Dengan Menggunakan Pendekatan Service Oriented Architecture (Soa)

STMIK AMIKOM Laboratory section in Yogyakarta as the laboratory Manager currently has two web-based information system is being used. The first is the Inventory information systems laboratory (SIIL), where this system handles things about stock inventory or equipment and supporting practical components. The system is run by a coordinator of the Hardware. The second is Reporting damage to information systems laboratory (SIPKL), in which this system works gives information of all forms of damage that occurs in the laboratory. This system is run by the whole officer Laboran. Because the two systems running singly, then access to information on the amount of equipment and components become more time consuming. Expected from Laboran is when access to SIPKL can find out the amount of stock the laboran equipment and components related to the damaged equipment and components so that it can take decisions.See the above, needed further integration of the two systems of the different information so that it can provide a quick, accurate information, complete and integrated without having to change the existing system. In this study researchers proposed an integration of process planning information system as a strategy of development information for The laboratory of STMIK AMIKOM Yogyakarta to fit the needs of your organization using the Service Oriented Architecture approach (SOA) in the process of the integration of information systems.Service Oriented Architecture (SOA) is a way of designing applications using components or existing services without having to change the existing system. Requires only the addition of modules that are used to integrate the system or in other words arranged in the form of modules (modular). SOA is more appropriate to integrate heterogeneous systems and easier to adapt to changing environments, more efficient and effective. One form of implementation of SOA is web services technology where data exchange can be made possible between different application platforms. This technology is widely applied to applications that are web-based.SOA approach to integration process between analysis and implementation as well as SIPKL SIIL technology web service then this research was later expected to produce the required information SIPKL where such information is already available at SIIL so you can help the decision making in the Act of handling problems of compute

Towards a Knowledge Graph Enhanced Automation and Collaboration Framework for Digital Twins

The Digital Twin (DT) provides a digital representation of a physical system and allows users to interactively study the physical processes of a real system via the digital representation in different scenarios in real time. The development of a DT is highly complex; it requires not only expertise from multiple disciplines but also the integration of often heterogeneous software components, e.g., simulations, machine learning, visualization, and user interface components across distributed environments. This poster presents a Knowledge Graph-based ontological framework to boost automation and collaboration during the DT lifecycle stages. We implement our methods in developing a what-if analysis service for a DT of an ecosystem of wetlands and its automated deployment to the Amazon Web Services (AWS) cloud.</p

Context-Aware Information Retrieval for Enhanced Situation Awareness

In the coalition forces, users are increasingly challenged with the issues of information overload and correlation of information from heterogeneous sources. Users might need different pieces of information, ranging from information about a single building, to the resolution strategy of a global conflict. Sometimes, the time, location and past history of information access can also shape the information needs of users. Information systems need to help users pull together data from disparate sources according to their expressed needs (as represented by system queries), as well as less specific criteria. Information consumers have varying roles, tasks/missions, goals and agendas, knowledge and background, and personal preferences. These factors can be used to shape both the execution of user queries and the form in which retrieved information is packaged. However, full automation of this daunting information aggregation and customization task is not possible with existing approaches. In this paper we present an infrastructure for context-aware information retrieval to enhance situation awareness. The infrastructure provides each user with a customized, mission-oriented system that gives access to the right information from heterogeneous sources in the context of a particular task, plan and/or mission. The approach lays on five intertwined fundamental concepts, namely Workflow, Context, Ontology, Profile and Information Aggregation. The exploitation of this knowledge, using appropriate domain ontologies, will make it feasible to provide contextual assistance in various ways to the work performed according to a user’s taskrelevant information requirements. This paper formalizes these concepts and their interrelationships

Semantics-Aware Services for the Mobile Computing Environment

Today's wireless networks and devices support the dynamic composition of mobile distributed systems according to networked services and resources. This has in particular led to the introduction of a number of computing paradigms, among which the Service-Oriented Architecture (SOA) seems to best serve these objectives. However, common SOA solutions restrict considerably the openness of dynamic mobile systems in that they assume a specific middleware infrastructure, over which composed system components have been pre-developed to integrate. On the other hand, the Semantic Web introduces a promising approach towards the integration of heterogeneous components; current semantics-based approaches are, however, restricted to application-level interoperability. Combining the elegant properties of software architecture modeling with the semantic reasoning power of the Semantic Web paradigm, this paper introduces abstract semantic modeling of mobile services that allows both machine reasoning about service composability and enhanced interoperability at both middleware and application level

Mediation of semantic web services in IRS-III

Business applications composed of heterogeneous distributed components or Web services need mediation to resolve data and process mismatches at runtime. This paper describes mediation in IRS-III, a framework and platform for developing WSMO-based Semantic Web Services. We present our approach to mediation within Semantic Web Services and highlight the role of WSMO mediator types when solving mismatches at the semantic level between a service requester and a service provider. We describe the components of our mediation framework and how it can handle data, goal and process mediation during the activities of selection, composition and invocation of Semantic Web Services

A conceptual model for semantically-based e-government portals

Issues of semantic interoperability and service integration for e-government portals are the domain of interest of the present paper. We propose a Conceptual Model for One-Stop e-Government Portals based on the Semantic Web Service technology. We describe our research into building the three basic ontologies and their integration with standard ontologies. The result is a project-independent reusable model. At the same time, we outline a simple methodology for applying the proposed conceptual model into a specific scenario
