Personal advisors for business professionals: improving communication skills with online corpora

The business sphere is a multilingual world where foreign language communication skills are crucial in international relations. It makes employers look for business professionals who have a high level of linguistic competences. Language proficiency increases the chances of negotiation among partners. There are mainly two obstacles that make barriers in formal communication in a foreign language: lack of knowledge of specific linguistic structures or terminology and frequent transitions from one language to another. This paper contributes to the quest for quick access to a wide range of English, Spanish and Russian online databases that provide authentic language samples. Their application may improve communication skills and facilitate preparation for business discourse.

Leitura e sentido - estratégias para a compreensão de leitura em português (Língua materna) e em espanhol (Língua estrangeira)

Ler é um processo complexo que surge da necessidade de integrar os conhecimentos prévios do leitor com a informação presente num texto, e em estreita relação com os seus condicionantes pessoais, culturais e sociais. Trata-se, portanto de um processo interativo e dinâmico que se traduz na apropriação dos textos pelo leitor a partir da compreensão do significado e da (re)construção dos sentidos. Embora para um leitor eficiente possa constituir uma atividade que se desenvolve de forma automática e quase inconsciente, a leitura e a compreensão de leitura são processos que carecem de uma aprendizagem. Assim, consideramos que um dos aspetos mais relevantes no processo de ensino/aprendizagem é a consciencialização dos alunos relativamente à sua evolução pessoal e o desenvolvimento por parte do professor de estratégias diversificadas e flexíveis que visem a consecução dos objetivos propostos para a compreensão durante a leitura. Neste relatório, apresentamos o trabalho realizado no ano letivo 2013-2014 no Agrupamento de Escolas Gil Paes de Torres Novas no âmbito da Prática de Ensino Supervisionada. O principal objetivo da nossa intervenção pedagógica foi o de trabalhar didaticamente a leitura em língua materna (Português) e em língua estrangeira (Espanhol) em contexto escolar, destacando não só a importância das estratégias de leitura, mas também o ensino explícito das mesmas para uma melhor compreensão da leitura de acordo com os níveis de proficiência propostos.

A domain specific language for domotic systems

To cope with modernity, the interesting of having a fully automated house has been increasing over the years, as technology evolves and as our lives become more stressful and overloaded. An automation system provides a way to simplify some daily tasks, allowing us to have more spare time to perform activities where we are really needed. There are some systems in this domain that try to implement these characteristics, but this kind of technology is at its early stages of evolution being that it is still far away of empowering the user with the desired control over a habitation. The reason is that the mentioned systems miss some important features such as adaptability, extension and evolution. These systems, developed from a bottom-up approach, are often tailored for programmers and domain experts, discarding most of the times the end users that remain with unfinished interfaces or products that they have difficulty to control. Moreover, complex behaviors are avoided, since they are extremely difficult to implement mostly due to the necessity of handling priorities, conflicts and device calibration. Besides, these solutions are only reachable at very high costs, yet they still have the limitation of being difficult to configure by non-technical people once in runtime operation. As a result, it is necessary to create a tool that allows the execution of several automated actions, with an interface that is easy to use but at the same time supports all the main features of this domain. It is also desirable that this tool is independent of the hardware so it can be reused, thus a Model Driven Development approach (MDD) is the ideal option, as it is a method that follows those principles. Since the automation domain has some very specific concepts, the use of models should be combined with a Domain Specific Language (DSL). With these two methods, it is possible to create a solution that is adapted to the end users, but also to domain experts and programmers due to the several levels of abstraction that can be added to diminish the complexity of use. The aim of this thesis is to design a Domain Specific Language (DSL) that uses the Model Driven Development approach (MDD), with the purpose of supporting Home Automation (HA) concepts. In this implementation, the development of simple and complex scenarios should be supported and will be one of the most important concerns. This DSL should also support other significant features in this domain, such as the ability to schedule tasks, which is something that is limited in the current existing solutions.

About using serious games to teach (Portuguese) sign language

Sign language is the form of communication used by Deaf people, which, in most cases have been learned since childhood. The problem arises when a non-Deaf tries to contact with a Deaf. For example, when non-Deaf parents try to communicate with their Deaf child. In most cases, this situation tends to happen when the parents did not have time to properly learn sign language. This dissertation proposes the teaching of sign language through the usage of serious games. Currently, similar solutions to this proposal do exist, however, those solutions are scarce and limited. For this reason, the proposed solution is composed of a natural user interface that is intended to create a new concept on this field. The validation of this work, consisted on the implementation of a serious game prototype, which can be used as a source for learning (Portuguese) sign language. On this validation, it was first implemented a module responsible for recognizing sign language. This first stage, allowed the increase of interaction and the construction of an algorithm capable of accurately recognizing sign language. On a second stage of the validation, the proposal was studied so that the pros and cons can be determined and considered on future works.

It also collects data through the use of interview and questionnaire methods, and suggests the assessment and feedback types to be implemented at polytechnic school in Benguela

Aplicação da dramatização em aula como instrumento para o aperfeiçoamento da oralidade no ensino da língua materna (Português) e da língua estrangeira (Espanhol)

O tema do presente relatório é a dramatização como um procedimento didático nas aulas de língua – dramatização, enquanto método baseado no teatro (drama), como um processo de ensino-aprendizagem que articula os conteúdos de estudo escolar com técnicas e conceitos teatrais. O objetivo principal da aplicação desta metodologia é conseguir que o estudo das matérias da aula de língua seja interessante e motivador para os intervenientes, alunos e professor, procurando-se proporcionar aulas dinâmicas, com momentos de recreação que possibilitem a identificação do estudo com o prazer. Na organização das aulas usa-se um procedimento didático baseado no enfoque por tarefas, método educativo aplicado ao ensino-aprendizagem das línguas estrangeiras, particularmente na conceção de Ellis (2003) para um processo sequencial de ensino orientado, onde são considerados três momentos: as atividades anteriores à tarefa, a tarefa e as atividades posteriores à tarefa. No caso do presente estudo, consideram-se tarefas as atividades de natureza dramática que apresentam duas expressões diferentes: simulações de situações comunicativas reais, e leituras em voz alta, individualmente ou em diálogo, feitas para um público. A expressão oral manifesta-se através de vários modos: prática de diferentes formas de leitura em voz alta, atuação em simulações comunicativas e a interação oral entre alunos e professora na execução de muitas atividades. A relevância destas práticas orais prende-se com o seu potencial para desenvolverem as destrezas requeridas nos processos comunicativos da língua oral: a cognitiva, a linguística e a fonética. Ainda que o enfoque por tarefas seja um método para a didática das línguas estrangeiras, a sua aplicabilidade no ensino da língua materna é possível, seguindo a mesma sequenciação de operações num e noutro caso pois focalizar o estudo das línguas na sua funcionalidade comunicativa é o propósito das pedagogias atuais para as línguas, maternas ou estrangeiras.

Comparative analysis of Spanish Banks’ Standalone credit profile

The paper studies the relationship between four differently rated bank’s financial profile and their standalone credit rating issued by Moody’s. The comparative analysis shows an example that despite their pricing power and geographical coverage, larger banks do not necessarily have better credit ratings. Instead, business model and risk appetite seem to be the defining factors of banks’ vulnerability to shocks, such as the Spanish real estate crisis. The risk-return relationship is also identified in the banks’ fundamentals meaning that while expansionary strategy in riskier asset classes enhances margins, it also potentially distorts the credit risk profile.

Generic system for human-computer gesture interaction: applications on sign language recognition and robotic soccer refereeing

Hand gestures are a powerful way for human communication, with lots of potential applications in the area of human computer interaction. Vision-based hand gesture recognition techniques have many proven advantages compared with traditional devices, giving users a simpler and more natural way to communicate with electronic devices. This work proposes a generic system architecture based in computer vision and machine learning, able to be used with any interface for human-computer interaction. The proposed solution is mainly composed of three modules: a pre-processing and hand segmentation module, a static gesture interface module and a dynamic gesture interface module. The experiments showed that the core of visionbased interaction systems could be the same for all applications and thus facilitate the implementation. For hand posture recognition, a SVM (Support Vector Machine) model was trained and used, able to achieve a final accuracy of 99.4%. For dynamic gestures, an HMM (Hidden Markov Model) model was trained for each gesture that the system could recognize with a final average accuracy of 93.7%. The proposed solution as the advantage of being generic enough with the trained models able to work in real-time, allowing its application in a wide range of human-machine applications. To validate the proposed framework two applications were implemented. The first one is a real-time system able to interpret the Portuguese Sign Language. The second one is an online system able to help a robotic soccer game referee judge a game in real time.

Vision-based portuguese sign language recognition system

Vision-based hand gesture recognition is an area of active current research in computer vision and machine learning. Being a natural way of human interaction, it is an area where many researchers are working on, with the goal of making human computer interaction (HCI) easier and natural, without the need for any extra devices. So, the primary goal of gesture recognition research is to create systems, which can identify specific human gestures and use them, for example, to convey information. For that, vision-based hand gesture interfaces require fast and extremely robust hand detection, and gesture recognition in real time. Hand gestures are a powerful human communication modality with lots of potential applications and in this context we have sign language recognition, the communication method of deaf people. Sign lan- guages are not standard and universal and the grammars differ from country to coun- try. In this paper, a real-time system able to interpret the Portuguese Sign Language is presented and described. Experiments showed that the system was able to reliably recognize the vowels in real-time, with an accuracy of 99.4% with one dataset of fea- tures and an accuracy of 99.6% with a second dataset of features. Although the im- plemented solution was only trained to recognize the vowels, it is easily extended to recognize the rest of the alphabet, being a solid foundation for the development of any vision-based sign language recognition user interface system.

A domain-specific language for ETL patterns specification in Data Warehousing Systems

During the last few years many research efforts have been done to improve the design of ETL (Extract-Transform-Load) systems. ETL systems are considered very time-consuming, error-prone and complex involving several participants from different knowledge domains. ETL processes are one of the most important components of a data warehousing system that are strongly influenced by the complexity of business requirements, their changing and evolution. These aspects influence not only the structure of a data warehouse but also the structures of the data sources involved with. To minimize the negative impact of such variables, we propose the use of ETL patterns to build specific ETL packages. In this paper, we formalize this approach using BPMN (Business Process Modelling Language) for modelling more conceptual ETL workflows, mapping them to real execution primitives through the use of a domain-specific language that allows for the generation of specific instances that can be executed in an ETL commercial tool.
