The data model is one of the core problems in the field of XML data management, but at present the research on management of uncertain data supporting multi-dimensional continuous random variables has been limited. An extended data model supporting multi-dimensional continuous random variables was proposed based on the existing model. The new model made the continuous uncertain XML no longer confined...
Service composition, which provides a more effective way to combine several single services into a composite service, is a kind of software reuse techniques. However, one of the most important problems is how to perform service composition correctly and effectively so as to produce high-quality source codes for describing the resulted composite service. In this paper, we propose a model-driven method...
In this paper we describe the design and implementation of a framework for declarative XML languages-SMPL. The framework is intended to support the semantic structure, annotation and control of SMIL documents. SMPL is supported by all browsers de-facto. Unlike perhaps other Web standards, where adding functionality has to be included in a release of a new version for a plug-in or a Web browser, SMPL...
Web service discovery is a mechanism which facilitates an access to the Web service descriptions. UDDI facilitates the discovery based on the service functionality through keyword and category matching. Such discovery techniques do not consider the semantics and user context as they are too syntactic in nature. In this paper, we propose a well formed functional semantics to describe an operation of...
This paper presents reports a design and development of the interactive map using Scalable Vector Graphics (SVG) that can be used to find the shortest path. Using our interactive map, the user will be able to set the route or path to the desired location. If that path is congested, the map will find the second shortest path to the user. In the usability study, we have tested the map with the mean...
Model based intrusion detection mechanisms have produced encouraging results for reduced false alarms. This paper extends our earlier work, where we reported for sandboxing Linux 2.6 using code generated from policies. Here we pursue the problem of code generation from a set of policies extracted from a domain model. Such a technique can support the safeguarding of system resources. We also present...
The process of marking up the syntactic structure of the sentences in a corpus is facilitated by having a graphical tree editor. A type specification constraints the nature of acceptable trees, and visual indication of non-conformities makes corrections easy. Projectivity checking can also be a useful way to notice errors, depending on the linguistic design of the tree type specification. A small...
This paper presents realization of IPTV JSE application method based on embedded browser. It analyzes the steps based on global variable and local variable. And it analyzes the special processing method of the active event based on embedded browser. These JSE realization method based on embedded browser has perfect reference value to the design of EPG system development and design of the STB.
We describe XLambda, a functional language with XML syntax, and its processor which is implemented fully and completely in XSLT. XLambda has all the basic features of a functional language, such as defining named functions, operations on numbers, passing functions as parameters, constructing arbitrary data structures etc. What sets XLambda apart from the rest of the functional languages is not its...
Recently, there has been an increasing need in scientific workflows to solve the shimming problem, the use of a special kind of adaptors, called shims, to link related but incompatible workflow tasks. However, existing techniques produce scientific workflows that are cluttered with many visible shims, which distract a scientist's focus on functional components. Moreover, these techniques do not address...
Since numerous large-scale scientific applications executed on grids are expressed as complex scientific workflows, workflow management has appeared as one of the most important service in grid environment in past few years. However, most of the management systems do not fully hide the complexity of the underlying orchestration language. Meanwhile, grid environment is dynamic when each scientist involves...
The usage of the operating system, web browsers and other software applications leave activity traces that can represent confidential (sensitive) data. Specialized software products can identify most of these sensitive areas, however they do not offer an open architecture that allows the user to define his own sensitive areas. This paper implements an open definition language, called Open Sensitive...
The key problem in data integration systems is creating and maintaining mappings between schemas of heterogeneously structured data sources. The problem becomes increasingly important in P2P environment when new partners enter the system and their schemas evolve. In this work we focus on deriving mappings between XML schemas using their annotations in common domain ontology. A special attention is...
In this paper we describe an approach to build XML schemas in a collaborative way. The approach is based on computing intersection between sequences of type terms built over constants, function symbols and type symbols. For type symbols there may be the corresponding type rules that specify the (regular) set of term sequences the type symbol generates. We describe the intersection algorithm, prove...
As an example of SIMS (student information management system) developed independently by School of Information Science & Engineering of Shandong Normal University, this paper introduces database design, specific realization of each function module and key technologies used in the system. In the .NET environment, using ASP.NET technology, Visual C# and JavaScript as programming language, this system...
With the emergence of new business, the traditional Internet products can no longer meet the diverse needs of market. It costs much to develop new businesses and lots of the work in the development is reduplicate. So the best way is to find a solution that enables us to use the existing business to meet the change in demand. Service oriented architecture (SOA) with Web service technology can transform...
Normalization theory is necessary for designing a good XML document. A good document means that it has minimal redundancy. The research on XML functional dependency and normalization is still an open problem. This paper first presents a path language of XML model, then proposes a new kind of XML functional dependency (XFD) that has stronger expression ability to XML functional dependency that can...
XML allows redundancy of data with its hierarchical structure where its elements may be nested and repeated. This will make the same information appear in more than one place; in fact it allows the same elements appear at different sub-trees. With this capability, XML is easier to understand and to parse, while to recover this information would require less joins. This is in contrast to relational...
The respond of traditional Web application to user interface is slow and wasting bandwidth, which bring user a lot of inconvenience, while the emergence of Ajax has changed this situation. Ajax can maintain data without refreshing the page, which greatly reduce the time of waiting for a large number of exchanged data for user. The advantages of both is fully demonstrated by the support which Struts2...
Life science workflow systems are developed to help life scientists to conveniently connect various programs and Web services. In practice however, much time is spent on data conversion, because Web services provided by different organisations use different data formats. We have analysed all the Taverna workflows available at the my Experiment Web site on December 11, 2008. Our analysis of the tasks...
