An ontology roadmap for crowdsourcing innovation intermediaries

Ontologies have proliferated in the last years, essentially justified by the need of achieving a consensus in the multiple representations of reality inside computers, and therefore the accomplishment of interoperability between machines and systems. Ontologies provide an explicit conceptualization that describes the semantics of the data. Crowdsourcing innovation intermediaries are organizations that mediate the communication and relationship between companies that aspire to solve some problem or to take advantage of any business opportunity with a crowd that is prone to give ideas based on their knowledge, experience and wisdom, taking advantage of web 2.0 tools. Various ontologies have emerged, but at the best of our knowledge, there isn’t any ontology that represents the entire process of intermediation of crowdsourcing innovation. In this paper we present an ontology roadmap for developing crowdsourcing innovation ontology of the intermediation process. Over the years, several authors have proposed some distinct methodologies, by different proposals of combining practices, activities, languages, according to the project they were involved in. We start making a literature review on ontology building, and analyse and compare ontologies that propose the development from scratch with the ones that propose reusing other ontologies. We also review enterprise and innovation ontologies known in literature. Finally, are presented the criteria for selecting the methodology and the roadmap for building crowdsourcing innovation intermediary ontology.

A construção de uma cultura de paz através do conhecimento em rede

As novas tecnologias representam desafios inovadores e novas oportunidades para todos os cidadãos e países, independentemente do seu nível de desenvolvimento. Porém, os que perderem esta onda tecnológica encontrarão barreiras que limitarão o seu crescimento, pelo que há assim necessidade de um contributo global para que a tendência tecnológica se implemente democraticamente e venha a contribuir para o bem-estar dos cidadãos. Esta comunicação promove uma reflexão sobre as potencialidades da Web 2.0 na construção de uma cultura de paz e desafia toda a comunidade de educadores para a paz para uma participação activa na sociedade do conhecimento, uma sociedade em rede. Neste sentido, apresentámos boas práticas como possíveis modelos que impulsionem o nascimento de outras práticas colaborativas.

Terminology as a sensemaking social tool

Since the middle of the first decade of this century, several authors have announced the dawn of a new Age, following the Information/ Knowledge Age (1970-2005?). We are certainly living in a Shift Age (Houle, 2007), but no standard designation has been broadly adopted so far, and others, such as Conceptual Age (Pink, 2005) or Social Age (Azua, 2009), are only some of the proposals to name current times. Due to the amount of information available nowadays, meaning making and understanding seem to be common features of this new age of change; change related to (i) how individuals and organizations engage with each other, to (ii) the way we deal with technology, to (iii) how we engage and communicate within communities to create meaning, i.e., also social networking-driven changes. The Web 2.0 and the social networks have strongly altered the way we learn, live, work and, of course, communicate. Within all the possible dimensions we could address this change, we chose to focus on language – a taken-for-granted communication tool, used, translated and recreated in personal and geographical variants, by the many users and authors of the social networks and other online communities and platforms. In this paper, we discuss how the Web 2.0, and specifically social networks, have contributed to changes in the communication process and, in bi- or multilingual environments, to the evolution and freeware use of the so called “international language”: English. Next, we discuss some of the impacts and challenges of this language diversity in international communication in the shift age of understanding and social networking, focusing on specialized networks. Then we point out some skills and strategies to avoid babelization and to build meaningful and effective content in mono or multilingual networks, through the use of common and shared concepts and designations in social network environments. For this purpose, we propose a social and collaborative approach to terminology management, as a shared, strategic and sense making tool for specialized communication in Web 2.0 environments.

BIWiki - Using a Business Intelligence Wiki to Form a Virtual Community of Practice for Portuguese Master's Students

Web 2.0 software in general and wikis in particular have been receiving growing attention as they constitute new and powerful tools, capable of supporting information sharing, creation of knowledge and a wide range of collaborative processes and learning activities. This paper introduces briefly some of the new opportunities made possible by Web 2.0 or the social Internet, focusing on those offered by the use of wikis as learning spaces. A wiki allows documents to be created, edited and shared on a group basis; it has a very easy and efficient markup language, using a simple Web browser. One of the most important characteristics of wiki technology is the ease with which pages are created and edited. The facility for wiki content to be edited by its users means that its pages and structure form a dynamic entity, in permanent evolution, where users can insert new ideas, supplement previously existing information and correct errors and typos in a document at any time, up to the agreed final version. This paper explores wikis as a collaborative learning and knowledge-building space and its potential for supporting Virtual Communities of Practice (VCoPs). In the academic years (2007/8 and 2008/9), students of the Business Intelligence module at the Master's programme of studies on Knowledge Management and Business Intelligence at Instituto Superior de Estatistica e Gestao de Informacao of the Universidade Nova de Lisboa, Portugal, have been actively involved in the creation of BIWiki - a wiki for Business Intelligence in the Portuguese language. Based on usage patterns and feedback from students participating in this experience, some conclusions are drawn regarding the potential of this technology to support the emergence of VCoPs; some provisional suggestions will be made regarding the use of wikis to support information sharing, knowledge creation and transfer and collaborative learning in Higher Education.

Uma formação útil para a literacia no novo contexto de Bolonha

A Declaração de Bolonha (1999) obrigou a mudanças várias, reconfigurando os modelos formativos no espaço europeu do ensino superior, até 2010. A partir de 2006, em Portugal, com a criação e adequação dos cursos superiores existentes ao modelo de Bolonha, verificou-se uma generalizada redução da duração média dos diferentes ciclos de estudo e a definição de competências gerais e específicas para os cursos e estudantes. Reflecte-se sobre a importância da literacia da informação, conceito evolutivo e abrangente, que se pode traduzir, sumariamente, em saber quando e porquê se tem uma necessidade informacional, onde encontrar a informação, como avaliá-la, usá-la e comunicá-la de forma ética, incluindo as competências tecnológicas, definição que se inscreve na interdisciplinar Ciência da Informação e no comportamento informacional. Destaca-se a vantagem de uma formação para a literacia da informação no ensino superior, a qual contribuirá, certamente, para dotar os estudantes das referidas competências e melhorá-las. Defende-se a necessidade de uma desejável inter-acção entre múltiplos agentes educativos, com destaque para a trilogia estudantes, bibliotecários e professores, sendo os primeiros encarados como protagonistas activos das suas aprendizagens e devendo ser dotados de competências de literacia da informação, factor determinante para o seu sucesso. Quanto ao Bibliotecário, dotado de novas competências, entre as quais as tecnológicas, deve ser um facilitador do processo de formação para a literacia - preferencialmente integrada num projecto pedagógico e no currículo - articulando a sua acção educativa com estudantes e docentes. Corroborando a extensão educativa das Bibliotecas e aliando-a ao uso inevitável das novas tecnologias da informação e comunicação, sublinha-se o papel das Bibliotecas Digitais, que podem corresponder eficientemente aos anseios dos utilizadores no acesso a uma informação de qualidade, de forma cómoda, rápida, a baixo custo, com personalização dos serviços online, com inter-acção e socialização, através de ferramentas de edição colaborativa, típicas da Web 2.0.

Formação para a literacia da informação: uma interactividade necessária com os media

Our aim is to analyse the relationship between interactive media and its use in Education when applied to formal training for information literacy. Contextualizing the notion of literacy in an evolving framework and emphasizing the recognition of its importance, we highlight some desirable skills in the current information society, including, inevitably, technological competencies. When considering the notion of literacy within an evolving framework and emphasizing the acknowledgement of its significance some desirable skills stand out in the current information society including, inevitably, the technological skills. We emphasize media literacy and select some strategies for teaching and learning practices recommended for the development of new skills, highlighting the contribution of some international literacy standards and describing some of the good practices in Education. We also underline the need for training within an holistic perspective, integrating student’, teachers and staff cooperation in the educational process. In this process, the potential of the Web 2.0, which grants the new information users – the prosumers (consumers and producers) a new statute, new powers and obligations, is indeed worth mentioning. Regarding the situation, we shall quote the reports on the experiences of virtual learning communities that use the moodle platform and mention several activities and programs managed by the Portuguese government to increase the citizens’ literacy’s levels. In conclusion, we point out the need for lifelong learning and the ability of individuals to “learn to learn” who therefore provide literacy with a dynamic component.
