TCRIO: tecnologia de criatividade relacional inteligente on-line

No âmbito dos contextos de aprendizagem de projeto em Design, nas instituições de Ensino Superior, é cada vez mais frequente a utilização de plataformas de gestão das aprendizagens on-line (LMS) no suporte às atividades curriculares à distância. Contudo estes sistemas apesar de darem um precioso contributo através da gestão de conteúdos, das funcionalidades ligadas à avaliação dos alunos e da comunicação entre pares, respondem de forma ineficiente a outras necessidades específicas de alunos e professores no desenvolvimento de unidades curriculares de Design ligadas à aprendizagem de projeto. Este fato contribuiu para que recorrêssemos às tecnologias móveis e sociais na procura de uma solução que melhor se ajuste à aplicação das novas metodologias de e-learning adaptadas a este tipo de contextos. Partindo dessa constatação desenvolvemos e testámos um modelo tecnológico que julgamos introduzir vantagens bastante significativas na definição de novas metodologias de suporte on-line a contextos de aprendizagem personalizada (PLE) em disciplinas ligadas à aprendizagem colaborativa de projeto em Design. Através do levantamento de necessidades detetadas no terreno e da análise da oferta tecnológica existente, reunimos um conjunto de requisitos que nos permitiu desenvolver o protótipo de um sistema tecnológico que fundamenta a totalidade do modelo teórico que propomos em resposta aos pressupostos equacionados no início deste relatório.

Model of access to natural language sources in electronic government

For the actual existence of e-government it is necessary and crucial to provide public information and documentation, making its access simple to citizens. A portion, not necessarily small, of these documents is in an unstructured form and in natural language, and consequently outside of which the current search systems are generally able to cope and effectively handle. Thus, in thesis, it is possible to improve access to these contents using systems that process natural language and create structured information, particularly if supported in semantics. In order to put this thesis to test, this work was developed in three major phases: (1) design of a conceptual model integrating the creation of structured information and making it available to various actors, in line with the vision of e-government 2.0; (2) definition and development of a prototype instantiating the key modules of this conceptual model, including ontology based information extraction supported by examples of relevant information, knowledge management and access based on natural language; (3) assessment of the usability and acceptability of querying information as made possible by the prototype - and in consequence of the conceptual model - by users in a realistic scenario, that included comparison with existing forms of access. In addition to this evaluation, at another level more related to technology assessment and not to the model, evaluations were made on the performance of the subsystem responsible for information extraction. The evaluation results show that the proposed model was perceived as more effective and useful than the alternatives. Associated with the performance of the prototype to extract information from documents, comparable to the state of the art, results demonstrate the feasibility and advantages, with current technology, of using natural language processing and integration of semantic information to improve access to unstructured contents in natural language. The conceptual model and the prototype demonstrator intend to contribute to the future existence of more sophisticated search systems that are also more suitable for e-government. To have transparency in governance, active citizenship, greater agility in the interaction with the public administration, among others, it is necessary that citizens and businesses have quick and easy access to official information, even if it was originally created in natural language.
