Designing an ontology-based Zika virus news authoring environment for the semantic web

This paper describes the experience of researching and teaching the conceptual and practical basis for the specification, modelling and design of an ontology-based news authoring environment for the Semantic Web, that takes into account the construction and use of an ontology of the Zika disease. Some CMSs are being adapted in order to receive semantic features, such as automatic generations of keywords, semantic annotation and tagging, content reviewing etc. We present here the infrastructure designed to foster research on semantic CMSs as well as semantic web technologies that can be integrated into an ontology-based news authoring environment

Anotação semi-automática baseada em ontologia, busca e relacionamento semântico entre textos : proposta para um sistema de gerenciamento de conteúdo

Trabalho de Conclusão de Curso (graduação)—Universidade de Brasília, Instituto de Ciências Exatas, Departamento de Ciência da Computação, 2018.A semântica ainda é um desafio para a automação e para a melhoria do relacionamento entre homem e máquina. Os sistemas de gerenciamento de conteúdo apresentam várias possibilidades de melhoria com o processamento semântico. Uma redação jornalística com um sistema de gerenciamento de conteúdo que possibilite busca semântica, relacionamento semântico entre artigos jornalísticos e comunicação com sistemas semânticos externos pode incrementar a capacidade produtiva dos profissionais e facilitar a vida de quem consome o conteúdo, por exemplo. Este trabalho apresenta um protótipo funcional de um sistema de gerenciamento de conteúdo semântico com foco na construção de anotações semânticas semi-automáticas baseadas em uma ontologia de domínio, reutilizar as anotações para busca e construção de relacionamentos entre textos armazenados no sistema e prover uma interface semântica para acesso do conteúdo do sistema por sistemas externos ao sistema de informação no qual possa ser implantado. São apresentados o algoritmo de anotação, os casos de uso de anotação, criação e edição de artigos, uma abordagem para busca semântica dos mesmos e duas abordagens para construção de relacionamentos entre os textos anotados. O sistema aumenta muito a velocidade em que se pode anotar semanticamente um artigo além permitir que o usuário adicione e remova anotações que foram sugeridas automaticamente. As duas abordagens para relacionamento de textos se mostraram bastante precisas e úteis. A ferramenta de busca é muito versátil por permitir a busca em campos de dados semânticos e não semânticos ao mesmo tempo e também o uso de operadores lógicos em todos eles.Semantics is still a challenge to automation and to the improvement of the relationship between humans and machines. The content management systems have a lot of improvement possibilities using semantics. A news writing with a content management system that provides semantic search, semantic relationships between articles and communication with external semantic systems can improve the productivity of the writers and make the reader task easier. This work presents a functional prototype of a content management system that focus in the construction of semantic annotations based on domain ontology, reuse annotations in search and relationship construction between stored texts and provide a semantic interface for external systems. Are presented the annotation algorithm, the use cases of annotation, article creation and editing, an approach for for a semantic search and two approaches for build semantic relationships between texts. The system enable users two create semantic annotations quickly and allow them to remove and add annotations that were suggested or not by the annotations algorithm. The two approaches for semantic relationships between texts are accurate and useful. The search tool is versatile because it allows users to search in semantic and non semantic fields at the same time and use logic operators in all fields

Newsroom 3.0: Managing Technological and Media Convergence in Contemporary Newsrooms

News consumers are changing their way of accessing and interacting with news content, of which they are now prosumers (combined producers and consumers). Consequently, communication organizations are facing great challenges posed by the decrease of paying readers and the competition imposed by emergent technologies that allow new forms to produce and disseminate news. To understand the role of the journalists and their managers in this challenge, we investigate how top news organizations are tackling this crisis. The results of this research, of a qualitative and exploratory nature, led us to propose a framework - Newsroom 3.0 - of a collaborative environment to support the production of news in an integrated, convergent and cybernetic newsroom. Newsroom 3.0 will provide support to the work of interdisciplinary teams, in respect of the coordination of the activities developed, as well as the cooperative production of content and communication between newsroom professionals and news prosumers

Front-Line Physicians' Satisfaction with Information Systems in Hospitals

Day-to-day operations management in hospital units is difficult due to continuously varying situations, several actors involved and a vast number of information systems in use. The aim of this study was to describe front-line physicians' satisfaction with existing information systems needed to support the day-to-day operations management in hospitals. A cross-sectional survey was used and data chosen with stratified random sampling were collected in nine hospitals. Data were analyzed with descriptive and inferential statistical methods. The response rate was 65 % (n = 111). The physicians reported that information systems support their decision making to some extent, but they do not improve access to information nor are they tailored for physicians. The respondents also reported that they need to use several information systems to support decision making and that they would prefer one information system to access important information. Improved information access would better support physicians' decision making and has the potential to improve the quality of decisions and speed up the decision making process.Peer reviewe

European Distance and E-Learning Network (EDEN). Conference Proceedings

Erasmus+ Programme of the European UnionThe powerful combination of the information age and the consequent disruption caused by these unstable environments provides the impetus to look afresh and identify new models and approaches for education (e.g. OERs, MOOCs, PLEs, Learning Analytics etc.). For learners this has taken a fantastic leap into aggregating, curating and co-curating and co-producing outside the boundaries of formal learning environments – the networked learner is sharing voluntarily and for free, spontaneously with billions of people.Supported by Erasmus+ Programme of the European Unioninfo:eu-repo/semantics/publishedVersio

Congress UPV Proceedings of the 21ST International Conference on Science and Technology Indicators

This is the book of proceedings of the 21st Science and Technology Indicators Conference that took place in València (Spain) from 14th to 16th of September 2016. The conference theme for this year, ‘Peripheries, frontiers and beyond’ aimed to study the development and use of Science, Technology and Innovation indicators in spaces that have not been the focus of current indicator development, for example, in the Global South, or the Social Sciences and Humanities. The exploration to the margins and beyond proposed by the theme has brought to the STI Conference an interesting array of new contributors from a variety of fields and geographies. This year’s conference had a record 382 registered participants from 40 different countries, including 23 European, 9 American, 4 Asia-Pacific, 4 Africa and Near East. About 26% of participants came from outside of Europe. There were also many participants (17%) from organisations outside academia including governments (8%), businesses (5%), foundations (2%) and international organisations (2%). This is particularly important in a field that is practice-oriented. The chapters of the proceedings attest to the breadth of issues discussed. Infrastructure, benchmarking and use of innovation indicators, societal impact and mission oriented-research, mobility and careers, social sciences and the humanities, participation and culture, gender, and altmetrics, among others. We hope that the diversity of this Conference has fostered productive dialogues and synergistic ideas and made a contribution, small as it may be, to the development and use of indicators that, being more inclusive, will foster a more inclusive and fair world

Through a Model, Darkly: An Investigation of Modellers’ Conceptualisation of Uncertainty in Climate and Energy Systems Modelling and an Application to Epidemiology

Policy responses to climate change require the use of complex computer models to understand the physical dynamics driving change, to evaluate its impacts and to evaluate the efficacy and costs of different mitigation and adaptation options. These models are often complex and built by large teams of dedicated researchers. All modelling requires assumptions, approximations and analytic conveniences to be employed. No model is without uncertainty. Authors have attempted to understand these uncertainties over the years and have developed detailed typologies to deal with them. However, it remains unknown how modellers themselves conceptualise the uncertainty inherent in their work. The core of this thesis involves the interviews of 38 modellers from climate science, energy systems modelling and integrated assessment to understand how they conceptualise the uncertainty in their work. This study finds that there is diversity in how uncertainty is understood and that various concepts from the literature are selectively employed to organise uncertainties. Uncertainty analysis is conceived as consisting of different phases in the model development process. The interplay between the complexity of the model and the capacities of modellers to manipulate these models shapes the ways in which uncertainty can be conceptualised. How we can attempt to wrangle with uncertainty in the present is determined by the path-dependent decisions made in the past; decisions that are influenced by a variety of factors within the context of the model’s creation. Furthermore, this thesis examines the application of these concepts to another field, epidemiology, to examine their generalisability in other contexts. This thesis concludes that in a situation such as climate change, where the nature of the problem changes in a dynamic way, emphasis should be placed on reducing the grip of these path dependencies and the resource costs of adapting models to face new challenges and answer new policy questions
