""As map-based visualizations of documents become more ubiquitous, there is a greater need for them to support intellectual and creative high-level cognitive activities with collections of non-cartographic materials — documents. This dissertation concerns the conceptualization of map-based visualizations as tools for sensemaking and collection understanding. As such, map-based visualizations would help people use georeferenced documents to develop understanding, gain insight, discover knowledge, and construct meaning.

This dissertation explores the role of graphical representations (such as maps, Kohonen maps, pie charts, and other) and interactions with them for developing map-based visualizations capable of facilitating sensemaking activities such as collection understanding. While graphical representations make document collections more perceptually and cognitively accessible, interactions allow users to adapt representations to users’ contextual needs. By interacting with representations of documents or collections and being able to construct representations of their own, people are better able to make sense of information, comprehend complex structures, and integrate new information into their existing mental models. In sum, representations and interactions may reduce cognitive load and consequently expedite the overall time necessary for completion of sensemaking activities, which typically take much time to accomplish.

The dissertation proceeds in three phases. The first phase develops a conceptual framework for translating ontological properties of collections to representations and for supporting visual tasks by means of graphical representations. The second phase concerns the cognitive benefits of interaction. It conceptualizes how interactions can help people during complex sensemaking activities. Although the interactions are explained on the example of a prototype built with Google Maps, they are independent of Google Maps and can be applicable to various other technologies. The third phase evaluates the utility, analytical capabilities and usability of the additional representations when users interact with a visualization prototype – VIsual COLlection EXplorer. The findings suggest that additional representations can enhance understanding of map-based visualizations of library collections: specifically, they can allow users to see trends, gaps, and patterns in ontological properties of collections.""

Web services are becoming a major technology for deploying automated interactions between distributed and heterogeneous applications, and for connecting business processes. Service mashups indicate a way to create new Web applications by combining existing Web resources utilizing data and Web APIs. They facilitate the design and development of novel and modern Web applications based on easy-to-accomplish end- user service compositions.

ABSTRACT
In today’s environment most of the commercial web based project developed in the industry as well enumerous number of funded project/and studies taken as part of research oriented initiatives in the
academia suffer from major technical issues as to how design, develop and deploy the Web Services that can run in variety of heterogeneous environments. In this paper we address the issues of interoperability between Web Services, the metrics which can be used to measure the interoperability
and simulate the Online shopping application by developing the Credit Card Verification Software using Luhn’s Mod 10 algorithm having Java Client written in NetBeans and the BankWebService in C# .NET

Web Services (WS) are used for
development of distributed applications
containing native code assembled with
references to remote Web Services. There
are thousands of Web Services available on
Web but the problem is how to find an
appropriate WS by discovering its details,
i.e. description of functionality of object
methods exposed for public use. Several
models have been suggested, some of them
implemented, but so far none of them
allowing systematic, publicly available,
search.
This paper suggests a model for publishing
WS in a flexible way which allows an
automated way of finding the desired Web
Service by category and/or functionality
without having to access any dedicated
servers. The search results in a narrow set
of Web Services suitable for problem
solution according to the user specification.

Service analyzer requires automated approach to access Subset Service, so that cost can be reduced by organizing the test scenarios. Emphasis of analyzer is to access and handle subset of code. This paper proposed a conceptual model that access Subset Service in two steps. First, slicing the Web service based on Subset WSDL (SWSDL) to access Subset Service. Second, the Subset Service is categorized into five layers. This improves and optimizes cost of Web service analysis by slicing and layering the Service. We conducted case studies for few Service projects. SWSDLs are used for Operationalized and Parameterized Web service analysis.

Today the ability to seamlessly exchange information between internal business processes, customers, and partners is vital for success. The organizations employ a variety of disparate applications that store and exchange data in dissimilar ways and therefore cannot "talk" to one another productively. Web services have evolved as a practical, cost-effective, deployment environment to realize dynamic and interoperable data integration between critical applications over operating system, platform, and language barriers that were previously impossible. This paper describes a service-oriented approach for the integration of a Web Portal and ERP application. We present a system architecture based on Web Service oriented framework in which both the applications are loosely connected through software components.

Researchers have recognized the need for more expressive descriptions of Web services. Most approaches have suggested using ontologies to either describe the Web services or to annotate syntactical descriptions of Web services. Earlier approaches are typically manual, and capability to support automatic or semi-automatic annotation is needed. The METEOR-S Web Service Annotation Framework (MWSAF) created at the LSDIS Lab at the University of Georgia leverages schema matching techniques for semi-automatic annotation. In this paper, we present an improved version of MWSAF.
Our preliminary investigation indicates that, by replacing the schema matching technique currently used for the categorization with a Naïve Bayesian Classifier, we can match web services with ontologies faster and with higher accuracy.

In this paper, a four-ball tribotester was used with standard test method IP-239 to evaluate friction and wear characteristics of normal lubricant, additive added lubricant and waste vegetable oil (WVO) contaminated lubricants. The balls used in four-ball tribotester were based on carbon-chromium steel ball bearings. The results obtained to present friction and wear characteristics are coefficient of friction (μ), wear scar diameter (WSD), flash temperature parameter (FTP), viscosity index (VI) and total acid number (TAN). Each test was conducted for five different loads from 50 kg to 90 kg with an interval of 10 kg. The lubricant was contaminated with WVO from 1% to 5%. The normal lubricant (as sample A) was used for comparison purposes. The test results showed that WVO contaminated lubricants with suitable anti-wear additive can reduce wear and friction coefficient. The objective of this investigation is to develop a new lubricant based on waste palm oil (such as WVO).

In this paper, we present a tool supported approach to perform efficient regression testing of web services. Functional and non-functional web service testing is done with the help of WSDL parsing and regression testing is performed by identifying the changes made thereafter. We identify, categorize, and capture the web service regression testing needs into three different categories, namely, changes in WSDL, changes in code, and selective re-testing of web service operations. To capture above three changes we proposed three intermediate forms of WSDL, namely, Difference WSDL (DWSDL), Unit WSDL (UWSDL), and Reduced WSDL (RWSDL), respectively. These intermediate forms of WSDLs are then combined to form Combined WSDL (CWSDL) which is further used for regression testing of the web service. This approach is prototyped as a tool, named as Automatic Web Service Change Management (AWSCM), which helps in performing the efficient regression testing of web services by selecting the relevant test cases to constructing reduced test suite from the old test suite file of SoapUI. The reduction in the effort for regression testing of web service is estimated by two proposed cost metrics. We present three case studies demonstrating the applicability of the proposed tool for the real world projects.

WS-BPEL is way to define business processes that interact with external entities through web service operations using WSDL. We have proposed BPEL-TC, an extension to existing WS-BPEL which uses temporally customized Web Services (WSDL-TC) as a model for process decomposition and assembly. WSDL-TC handles both backward compatible and incompatible changes and also maintains various versions of the artifacts that results due to changes over time and customizations desired by the users. In this paper, we are using pi-calculus to formalize Business Process Execution Language- Temporal Customization (BPEL-TC) process. π -calculus is a model of computation for concurrent systems along with changing connectivity of interactive systems. Pi-calculus is an extension of the process algebra CCS,
with added mobility to CCS while preserving its algebraic properties.

This paper shows that the problem of web services representation is crucial and analyzes the various
factors that influence on it. It presents the traditional representation of web services considering traditional
textual descriptions based on the information contained in WSDL files. Unfortunately, textual web services descriptions are dirty and need significant cleaning to keep only useful information. To deal with this problem, we introduce rules based text tagging method, which allows filtering web service description to keep only significant information. A new representation based on such filtered data is then introduced.
Many web services have empty descriptions. Also, we consider web services representations based on the WSDL file structure (types, attributes, etc.). Alternatively, we introduce a new representation called symbolic reputation, which is computed from relationships between web services. The impact of the use of these representations on web service discovery and recommendation is studied and discussed in the
experimentation using real world web services.

The current WSDL standard operates at the syntactic level and lacks the semantic expressivity needed to represent the requirements and capabilities of Web Services. Semantics can improve software reuse and discovery, significantly facilitate composition of Web services and enable integrating legacy applications as part of business process integration. The Web Service Semantics technical note defines a mechanism to associate semantic annotations with Web services that are described using Web Service Description ...

Semantic Web Services (SWSs) aim to improve the possibilities for automated discovery, composition and invocation of Web Services by providing ontology-based service descriptions expressed in a formal language. Several approaches have been driving the development of Semantic Web Service frameworks such as OWL-S (Ontology Web Language for Services), WSMO (Web Service Modeling Ontology) and WSDL-S (Semantic Annotation of Web Service Description Language descriptions). This paper focuses on WSMO; it aims to give a service ontology specification according to WSMO and using the reverse engineering techniques.

In this paper, Investigating SOAP and XML technologies in web service is studied. The reason for using XML technology to transmit data and also the need for application of existing communicative structure in SOAP technology in web pages with WSDL technology are investigated uniquely. And also the need for searchable address giving for web service which is available in UDDI technology and the advantages of using it are explained for programmers.

The World Wide Web is emerging not only as an infrastructure for data, but also for a broader variety of resources that are increasingly being made available as Web services. Relevant current standards like UDDI, WSDL, and SOAP are in their fledgling years and form the basis of making Web services a workable and broadly adopted technology. However, realizing the fuller scope of the promise of Web services and associated service oriented architecture will requite further technological advances in the areas of service interoperation, service discovery, service composition, and process orchestration. Semantics, especially as supported by the use of ontologies, and related Semantic Web technologies, are likely to provide better qualitative and scalable solutions to these requirements. Just as semantic annotation of data in the Semantic Web is the first critical step to better search, integration and analytics over heterogeneous data, semantic annotation of Web services is an equally critical first step to achieving the above promise. Our approach is to work with existing Web services technologies and combine them with ideas from the Semantic Web to create a better framework for Web service discovery and composition. In this paper we present MWSAF (METEOR-S Web Service Annotation Framework), a framework for semi-automatically marking up Web service descriptions with ontologies. We have developed algorithms to match and annotate WSDL files with relevant ontologies. We use domain ontologies to categorize Web services into domains. An empirical study of our approach is presented to help evaluate its performance.

Web Services testing is essential to achieve the goal of scalable, robust and successful Web Services especially in business environment where maybe exist hundreds of Web Services working together. This Relatively new way of software development brings out new issues for Web Service testing to ensure the quality of service that are published, bound, invoked and integrated at runtime. Testing services poses new challenges to traditional testing approaches. Dynamic scenario of Service Oriented Architecture (SOA) is also altering the traditional view of security and causes new risks. The great importance of this field has attracted the attention of researchers. In this paper, in addition of presenting a survey and classification of the main existing web service testing approaches, web service security testing researches and their issues are investigated.

At present the discovery techniques are registry-based and rely on syntactic and sometimes semantic descriptions of Web services' interfaces. Registries have several drawbacks: for instance, syntactic discovery returns results with low precision. Web services are treated as independent elements in these registries and present registries don't record services' past interactions. To address these issues, this paper embrace social networks to record past interactions and to develop that refer to here as social Web services. This requires first building and maintaining Web services' social networks and then using them to find, for example, highly collaborative peers. Service engineers often struggle to locate the relevant Web services needed to satisfy users' requests. In this paper it is also described that how service engineers can capitalize on Web services' interactions -namely, collaboration, substitution, and competition -to build social web service application for service discovery.

Numerous Web services and APIs available online have triggered the creation of mashups. They manage to provide added value by timely and flexible reuse and combination of existing data or software components to satisfy ad hoc needs. Most mashups strive for end-user friendliness and certain types of them are increasingly adopted by enterprises. In this paper, based on a review of recent literature and some enterprise mashup tools, we identify the current trends in the domain of user-centric enterprise mashups. Then we discuss the implications and challenges related to the enterprise mashup adoption.

Specification-based regression testing of web services is an important activity which verifies the quality of web services. A major problem in web services is that only provider has the source code and both user and broker only have the XML based specification. So from the perspective of user and broker,
specification based regression testing of web services is needed. The existing techniques are code based. Due to the dynamic behavior of web services, web services undergo maintenance and evolution process rapidly. Retesting of web
services is required in order to verify the impact of changes. In this paper, we present an automated safe specification based regression testing approach that uses original and modified WSDL specifications for change identification. All the relevant test cases are selected as reusable hence our regression test
selection approach is safe
