Integração de sistema educativo Cabo-verdiano utilizando Web Services O caso das matrículas

O sistema educativo Cabo-verdiano é um universo constituído por escolas públicas e privadas, do nível pré-escolar ao nível do ensino superior. Dentro desse sistema nós vamos fundamentar os processos administrativos, que foca basicamente o processo de matrícula do aluno, no sistema de ensino vigente, até deixar o sistema, incluindo também o processo de emissão de certificados, visto que no acto das matrículas são requeridas certificados do ano transacto. A proposta de Integração, é a utilização do poder das tecnologias de comunicação e informação para interligar as instituições de ensino, de forma que a matricula dos alunos não seja algo cansativo com elevados processos burocráticos e custoso, para quem quer seguir os seus estudos, e também tornar a gestão do sistema mais simples. O trabalho irá focar basicamente o objecto aluno, e todos os níveis de ensino, porque o aluno é o actor no sistema, quem irá interagir (Inscrever, solicitar, transferir e ser avaliado) nos diversos níveis de ensino. O aluno passa pelos diversos sistemas, na medida que pode passar do sistema de ensino básico, para o ensino secundário ao ensino superior. Contudo o aluno será o mesmo, consequentemente a identidade do aluno será a mesma para os diversos sistemas, o que altera são as avaliações e os planos curriculares, criando um histórico do aluno. Ele tem um ciclo de vida dentro do sistema de ensino. No entanto o estudo permitiu concluir, que o sistema educativo apresenta profundas lacunas no que tange a sua infra-estrutura tecnológica, que lhes permitirá ter mais dinâmica no processo de matrícula e emissão de certificados e na troca de informação entre os estabelecimentos, há dificuldade em criar um histórico do aluno de forma automática com toda a sua avaliação durante o seu ciclo de estudo, do primário ao superior. A proposta de tecnologias de integração entre as instituições, é baseado em métodos, nomeadamente, utilizando Web Services, que é um protocolo simples, que permite a interoperabilidade entre diversos sistemas. Funciona com o protocolo HTTP/HTTPs, que pode ser configurado e acedido facilmente nos Sistemas de Informação. As tecnologias Web constituem um excelente meio de para atingir o objectivo preconizado. Utilizando-as, as escolas poderão construir um sistema (Intranet), que pode ser acedida por todos as escolas e instituições do sistema educativo, com grandes benefícios, quer em termos pedagógicos como administrativo das instituições permitindo assim a partilha das informações internas, melhorando a comunicação entre os vários intervenientes.

Interoperability of learning objects copyright in the LUISA semantic learning management system

Semantic Web technology is able to provide the required computational semantics for interoperability of learning resources across different Learning Management Systems (LMS) and Learning Object Repositories (LOR). The EU research project LUISA (Learning Content Management System Using Innovative Semantic Web Services Architecture) addresses the development of a reference semantic architecture for the major challenges in the search, interchange and delivery of learning objects in a service-oriented context. One of the key issues, highlighted in this paper, is Digital Rights Management (DRM) interoperability. A Semantic Web approach to copyright management has been followed, which places a Copyright Ontology as the key component for interoperability among existing DRM systems and other licensing schemes like Creative Commons. Moreover, Semantic Web tools like reasoners, rule engines and semantic queries facilitate the implementation of an interoperable copyright management component in the LUISA architecture.

Semantic Web applications: a framework for industry and business exploitation – What is needed for the adoption of the Semantic Web from the market and industry

In recent years, Semantic Web (SW) research has resulted in significant outcomes. Various industries have adopted SW technologies, while the ‘deep web’ is still pursuing the critical transformation point, in which the majority of data found on the deep web will be exploited through SW value layers. In this article we analyse the SW applications from a ‘market’ perspective. We are setting the key requirements for real-world information systems that are SW-enabled and we discuss the major difficulties for the SW uptake that has been delayed. This article contributes to the literature of SW and knowledge management providing a context for discourse towards best practices on SW-based information systems.

Web Services In Symbian OS

This thesis presents different aspects of Web Services usage in Symbian OS that is an operating system for handheld devices. The practical part of the work was to develop Symbian OS client application for Web Services. It produced four reusable software components. XML enables platform and programming language independent services. Web Services use XML to create standardized message oriented services that are accessed through HTTP. Web Services are moving towards dynamic B2B interaction. Web Services increases the amount of transferred data, which is not desirable in mobile networks where transfer speed is slower than in the traditional networks. However the modern mobile networks are able to transfer the extra payload with reasonable time. XML processing is not a big problem. Web Services can be accessed from the modern mobile devices and they can cut down the development costs.

Web Services osana sovellusintegraatiota toiminnanohjausjärjestelmässä

Työssä esitellään Web Services -konseptia ja sovellusintegraatiota, sekä toteutetaan toiminnanohjausjärjestelmästä yrityksen asiakkaalle tietoja välittävään palveluun tuki Web Services -arkkitehtuurille. Palvelun tehtävänä on huolehtia yrityksen ja sen liiketoimintakumppaneiden välisestä XML-pohjaisesta viestiliikenteestä. Työn teoriaosassa perehdytään sovellusintegraatioon ja sen osa-alueisiin, Web Services -konseptiin ja -standardeihin sekä sen kanssa kilpaileviin tekniikoihin. Käytännön osuudessa toteutetaan paperiteollisuusyrityksen tilaus- ja toimitustietoja XML:n avulla lähettävään Java-pohjaiseen järjestelmään tuki SOAP-viesteille, sekä WSDL-kuvaukset palveluille. Työssä tutkitaan Web Services -arkkitehtuurin soveltuvuutta ja implementoinnin helppoutta toimintaohjausjärjestelmään. Tuloksena todetaan Web Services -arkkitehtuurin olevan mielenkiintoinen ja monella tapaa integrointia helpottava tekniikka. Arkkitehtuurin standardien puutteiden ja varhaisten versioiden takia tekniikan todetaan kuitenkin olevan monelta osin riittämätön ja epäkypsä toteuttamaan yritysten kriittisten järjestelmien integrointia.

Web services to link interlibrary software with OCLC WorldShare

Purpose - This article describes the use of web services to interconnect the GTBib interlibrary loan program with the OCLC WorldShare platform. Design/methodology/approach - We describe the current problem of duplication of procedures in libraries that have added their collections to the OCLC WorldCat catalogue in recent years and are therefore more likely to receive interlibrary loan requests through the WorldShare Platform. Findings - A solution that uses web services to insert and retrieve requests between the two systems is presented. Autonomous agents periodically check the status of the requests and keep them updated and synchronized. These agents also inform the library staff of any variation or inconsistency that is detected. Practical Implications - This technology reduces process management time by making it unnecessary to introduce the request data in both systems. Agents are used to check the consistency of statuses between the two systems, thus avoiding errors and omissions and improving the efficiency of the whole interlibrary loan process. Originality/value - This paper describes in detail the technical aspects of the solution as a reference for the development of future applications.

eLearning and Semantic Web

Semantic Web: Software agents on the Semantic Web may use commonly agreed service language, which enables co-ordination between agents and proactive delivery of learning materials in the context of actual problems. The vision is that each user has his own personalized agent that communicates with other agents.

Towards semantic web mining

Semantic Web Mining aims at combining the two fast-developing research areas Semantic Web and Web Mining. The idea is to improve, on the one hand, the results of Web Mining by exploiting the new semantic structures in the Web; and to make use of Web Mining, on overview of where the two areas meet today, and sketches ways of how a closer integration could be profitable.

Semantic web mining and the representation, analysis, and evolution of web space

Semantic Web Mining aims at combining the two fast-developing research areas Semantic Web and Web Mining. This survey analyzes the convergence of trends from both areas: Growing numbers of researchers work on improving the results of Web Mining by exploiting semantic structures in the Web, and they use Web Mining techniques for building the Semantic Web. Last but not least, these techniques can be used for mining the Semantic Web itself. The second aim of this paper is to use these concepts to circumscribe what Web space is, what it represents and how it can be represented and analyzed. This is used to sketch the role that Semantic Web Mining and the software agents and human agents involved in it can play in the evolution of Web space.

Semantic web mining

Semantic Web Mining aims at combining the two fast-developing research areas Semantic Web and Web Mining. This survey analyzes the convergence of trends from both areas: an increasing number of researchers is working on improving the results of Web Mining by exploiting semantic structures in the Web, and they make use of Web Mining techniques for building the Semantic Web. Last but not least, these techniques can be used for mining the Semantic Web itself. The Semantic Web is the second-generation WWW, enriched by machine-processable information which supports the user in his tasks. Given the enormous size even of today’s Web, it is impossible to manually enrich all of these resources. Therefore, automated schemes for learning the relevant information are increasingly being used. Web Mining aims at discovering insights about the meaning of Web resources and their usage. Given the primarily syntactical nature of the data being mined, the discovery of meaning is impossible based on these data only. Therefore, formalizations of the semantics of Web sites and navigation behavior are becoming more and more common. Furthermore, mining the Semantic Web itself is another upcoming application. We argue that the two areas Web Mining and Semantic Web need each other to fulfill their goals, but that the full potential of this convergence is not yet realized. This paper gives an overview of where the two areas meet today, and sketches ways of how a closer integration could be profitable.

Context Mediation in the Semantic Web: Handling OWL Ontology and Data Disparity through Context Interchange

The COntext INterchange (COIN) strategy is an approach to solving the problem of interoperability of semantically heterogeneous data sources through context mediation. COIN has used its own notation and syntax for representing ontologies. More recently, the OWL Web Ontology Language is becoming established as the W3C recommended ontology language. We propose the use of the COIN strategy to solve context disparity and ontology interoperability problems in the emerging Semantic Web – both at the ontology level and at the data level. In conjunction with this, we propose a version of the COIN ontology model that uses OWL and the emerging rules interchange language, RuleML.
