Modeling Semantic Web Services: The Web Service Modeling Language

Jos de Bruijn, Dieter Fensel, Mick Kerrigan et al. · 2008

Semantic Web services promise to automate tasks such as discovery, mediation, selection, composition, and invocation of services, enabling fully flexible automated e-business. Their usage, however, still requires a significant amount of human intervention due to the lack of support for a machine-processable description. In this book, Jos de Bruijn and his coauthors lay the foundations for understanding the requirements that shape the description of the various aspects related to Semantic Web services, such as the static background knowledge in the form of ontologies, the functional description of the service, and the behavioral description of the service. They introduce the Web Service Modeling Language (WSML), which provides means for describing the functionality and behavior of Web services, as well as the underlying business knowledge, in the form of ontologies, with a conceptual grounding in the Web Service Modeling Ontology. Academic and industrial researchers as well as professionals will find a comprehensive overview of the concepts and challenges in the area of Semantic Web services, the Web Services Modeling Language and its relation to the Web Services Modeling Ontology, and an in-depth treatment of both enabling technologies and theoretical foundations.

Web modeling-simulation:

Domingo, Carlos, Sananes, Marta, Tonella, Giorgio · Actualidad Contable FACES · 2005

Web modeling-simulation: Two strategies \n(Domingo, Carlos; Sananes, Marta; Tonella, Giorgio) \n\n\n\n\nAbstract\n\nThe paper presents an approach on how to exploit the benefits of Internet and the Web for promoting and improving the application of model and simulation techniques to a wide range of problems, specially in developing countries, where experts in this field are rather rare. \n\nThe approach is to use the Web for consulting services to offer choices of simulation paradigms and model development tools. Two complementary strategies are suggested: the Modeling-Simulation Consulting service and the Model-Simulation Diversity. The first includes, among others, the use of general information through the net, possibility to open a real and/or virtual dialogue between consulting and client, client oriented model database tools, client oriented model design editors, etc. The second uses the multi-paradigms approach offering modeling and simulation from the traditional off-line approach to run models in a standalone computer to on-line model building and simulation using net languages such as Java.

Modeling Web Interactions

Paul Graunke, et al. · 2003

Programmers confront a minefield when they design interactive Web programs. Web interactions take place via Web browsers. With browsers, consumers can whimsically navigate among the various stages of a dialog and can thus confuse the most sophisticated corporate Web sites. In turn, Web services can fault in frustrating and inexplicable ways. The quickening transition from Web scripts to Web services lends these problems immediacy. To address this programming problem, we develop a foundational model of Web interactions and use it to formally describe two classes of errors. The model suggests techniques for detecting both classes of errors. For one class we present an incrementally checked record type system, which effectively eliminates these errors. For the other class, we introduce a dynamic safety check, which catches the mistakes relative to programmers’ simple annotations.

Modeling Web Evolution

Michalis Vafopoulos, Efstathios Amarantidis, I. Αντωνίου · arXiv (Cornell University) · 2010

The Web is the largest human information construct in history transforming our society. How can we understand, measure and model the Web evolution in order to design effective policies and optimize its social benefit? Early measurements of the Internet traffic and the Web graph indicated the scale-free structure of the Web and other Complex Networks. Going a step further Kouroupas, Koutsoupias, Papadimitriou and Sideri (KKPS) presented an economic-inspired model which explains the scale-free behavior as the interaction of Documents, Users and Search engines. The purpose of this paper is to clarify the open issues arising within the KKPS model through analysis and simulations and to highlight future research developments in Web modeling, which is the backbone of Web Science.

Daniel A. Menascé, Daniel A. Menascé · 2008

The Web has experienced phenomenal growth and has become an important element of the information infrastructure of many organizations. Web performance and around-the-clock availability are the major concerns of Webmasters of sites that support mission-critical applications, such as electronic commerce. Web sites are complex computer systems consisting of many interconnected computers, networks, and routers.Some of the computers have specific functions such as authorization or caching. Workloads on Web sites are often unpredictable in nature. Heavy-load spikes and a large variability of the objects requested over the Web are unique characteristics of Web workloads. This paper reviews the important issues and challenges in modeling Web-based systems. Workload characterization, predictive models, and their use in various

Modeling Web Attachment Storage for Web Applications

Vijay Jain, Amol Kolambkar · 2014

Web application performance plays vital role in application usability and adaptability to its intended users. There are many factors, which attributes towards overall performance enhancements. One of them is that how efficiently a web application under peak load stores or retrieves the web-attached documents. In this paper, we have described a document storage and retrieval technique for improving web application performance. A technique suggested for the document storage purpose is based on the verification of results performed with various types and sizes of document attachments. Applying the suggested technique has shown an overall performance improvement for applications with web attachments.

Modeling "Web Of Trust" With Web 2.0

Omer Mahmood, S. Selvakennedy · Zenodo (CERN European Organization for Nuclear Research) · 2008

"Web of Trust" is one of the recognized goals for Web 2.0. It aims to make it possible for the people to take responsibility for what they publish on the web, including organizations, businesses and individual users. These objectives, among others, drive most of the technologies and protocols recently standardized by the governing bodies. One of the great advantages of Web infrastructure is decentralization of publication. The primary motivation behind Web 2.0 is to assist the people to add contents for Collective Intelligence (CI) while providing mechanisms to link content with people for evaluations and accountability of information. Such structure of contents will interconnect users and contents so that users can use contents to find participants and vice versa. This paper proposes conceptual information storage and linking model, based on decentralized information structure, that links contents and people together. The model uses FOAF, Atom, RDF and RDFS and can be used as a blueprint to develop Web 2.0 applications for any e-domain. However, primary target for this paper is online trust evaluation domain. The proposed model targets to assist the individuals to establish "Web of Trust" in online trust domain.

Modeling sensor web autonomy

A. J. Underbrink, Andrew Potter, K. Witt et al. · 2011

The research developed an architecture and experimental system for autonomously operating a web of Earth sensing devices. Example sensing devices include orbiting spacecraft, ground surface sensors, ocean surface sensors, ocean subsurface sensors, wheeled vehicles, fixed ground systems, weather balloons, and aircraft. A wide variety of sensors, sensor platforms, and operational characteristics (e.g., fixed versus mobile) required a common language for specifying and sharing data, information, and knowledge of the “sensor web”. An ontology was developed and used for collaboration between multiple sensor systems. The ontology is used by distributed agents to autonomously operate a sensor web in a distributed testbed. The system was also deployed and demonstrated on an orbiting satellite. The ontology models the application domain and the agent-based control system for the sensor web. The ontology was also used to implement the distributed agent system and to guide the design and development of the sensor web control system. The result is comprehensive model not only of the application domain, but also the control system for the application domain.

Web service conversation modeling

Boualem Benatallah, Fabio Casati, Farouk Toumani et al. · 2008

Web services are emerging as a promising technology for effectively automating interorganizational interactions.However,despite the growing interest, several issues remain to be addressed to provide Web services with benefits similar to what traditional middleware brings to intraorganizational application integration.In this article,the authors identify a framework that builds on current standards to help developers define extended service models and richer Web service abstractions. The framework’s main feature is a conversation metamodel derived from the authors ’ analysis of e-commerce portal sites. Web services are emerging as the technology of choice for application integration across companies and wide area networks. Yet despite growing interest and recent efforts, Web services middleware is still rather primitive in terms of functionality — far from what enterprise application integration (EAI) middleware can provide for intraenterprise applications. 1,2 As a result, Web service development remains a fairly complex activity. This article proposes a framework and a system that lets us embed functionality into the middleware that would otherwise have to be implemented by the service provider. Our aim is to assist users in the service-development, service-discovery, and service-interaction phases, thereby contributing to automating many aspects of the service-development life cycle. Our approach is based on the definition of a service description framework that builds on current standards — specifically, the Web Services Definition Language (WSDL) — and allows richer descriptions of services ’ characteristics. The main goal that guided the framework’s design was to enable service-property definition in a way that supports • humans in understanding properties, • client machines in searching for services, and • applications in automating the enforcement of the properties, much like transactional middleware supports transactional abstractions.

Web Service Modeling Ontology

Dumitru Roman, Uwe Keller, Holger Lausen et al. · Applied Ontology · 2005

The potential to achieve dynamic, scalable and cost-effective marketplaces and eCommerce solutions has driven recent research efforts towards so-called Semantic Web Services that are enriching Web services with machine-processable semantics. To this end, the Web Service Modeling Ontology (WSMO) provides the conceptual underpinning and a formal language for semantically describing all relevant aspects of Web services in order to facilitate the automatization of discovering, combining and invoking electronic services over the Web. In this paper we describe the overall structure of WSMO by its four main elements: ontologies, which provide the terminology used by other WSMO elements, Web services, which provide access to services that, in turn, provide some value in some domain, goals that represent user desires, and mediators, which deal with interoperability problems between different WSMO elements. Along with introducing the main elements of WSMO, we provide a logical language for defining formal statements in WSMO together with some motivating examples from practical use cases which shall demonstrate the benefits of Semantic Web Services.

Modeling Enterprise Web Applications

Shane Sendall, Alfred Strohmeier · Infoscience (Ecole Polytechnique Fédérale de Lausanne) · 2000

ABSTRACT The purpose of this paper is to provide an overview of our approach for modeling enterprise web applications (EWA), which is use case driven and uses UML as the modeling language. Our approach delivers a conceptual, logical model of the application, which consists of three packages. Packages were chosen to model three logical level concerns: presentation, business, and data management logic. Our approach uses the principle of separation of concerns, in that our package partition was made with the goal of isolating as many changes, which are commonly made in EWAs, as possible within a single package. In this paper, we focus on the business logic concern, and only give a brief overview of the preliminary techniques used to model the other two concerns. Also, we propose to model each concern with different views. Finally, we briefly discuss how our proposed logical model is mapped to process and deployment models to give a complete model of EWAs.

Conceptual Web Site Modeling

Bernahrd Strauch, Robert Winter · IGI Global eBooks · 2011

Current web site development is still dominated by technical issues. In order to enable efficient communication between developers and to provide a stable foundation for adopting new technologies, conceptual modeling of web sites is essential. Based on the state-of-the-art of conceptual modeling as implemented in current CASE environments, this paper tries to identify the “essence” of a web site and proposes an adequate conceptual model. The model is intended to capture not only hierarchical document structure and hypertext semantics, but also dynamic page generation from databases and various approaches to explicit and implicit navigation. It becomes evident that web sites can be regarded as supersets of traditional information systems, thereby requiring conceptual modeling to include various additional features. The proposed model comprises several classes of information objects, various types of associations, design rules, and quality checks. For illustration purposes, the model is applied to an existing web site. Current web site development tools are analyzed with regard to the extent to which conceptual web site modeling is supported.

Web based VRML modeling

Szilárd Kiss · Proceedings Fifth International Conference on Information Visualisation · 2002

Presents a method to connect VRML (Virtual Reality Modeling Language) and Java components in a Web page using EAI (External Authoring Interface), which makes it possible to interactively generate and edit VRML meshes. The meshes used are based on regular grids, to provide an interaction and modeling approach that uses the internal semantics of such a mesh by linking the available modeling operations to either single vertices, the vertices of a ring or column, or all the vertices from the VRML mesh. Our method permits strict mesh complexity control and scales the operations according to the mesh properties. We describe the structure of the system and provide a few examples of the meshes that were created.
