Social network analysis (SNA) has been explored in many contexts with different goals. Here, we use concepts from SNA for recommending collaborations academic networks. Recent work shows that research groups well connected networks tend to be more prolific. Hence, is useful increasing a group's connections, then boosting the group as collateral advantage. In this work, propose two new metrics or intensification of existing ones. Each metric considers social principle (homophily and...
O Projeto InformAÇÃO objetiva fomentar o Letramento Crítico de Dados em estudantes e educadores do Ensino Fundamental II Médio. Enfatizando a importância letramento dados na sociedade atual alinhando-se à BNCC (Base Nacional Comum Curricular), projeto realiza atividades mão massa princípios da teoria Construcionista para desenvolver habilidades analíticas críticas, preparando os participantes uma interação ética responsável com dados.
This paper presents the evaluation of a Recommender System for scientific articles in digital libraries. system is geared towards Computer Science community. Technologically speaking, proposed was developed under Semantic Web perspective since it explores its emergent technologies such as use standard metadata document description (i.e., Dublin Core), XML user's profile Lattes Curriculum Vitae), and services data providers (OAI) involved on recommendations' generation process. The focus this...
Some of the metrics more commonly used for Social Networks Analysis (SNA) do not consider weights relationships between actors analyzed Network, if it exists. These aim to measure importance relational ties and also are important be considered in a SNA. This paper purposes Gini Coefficient applied on Analysis. Our initial results demonstrate validity applicability this approach collaboration Brazilian network scientists.
This article defines, implements, and evaluates techniques to automatically compare recommend conferences. The for comparing conferences use familiar similarity measures a new measure based on co-authorship communities, called network community index. experiments reported in the indicate that technique performs better than other conferences, which is therefore first contribution of article. Then, focuses three families conference recommendation. family adopts collaborative filtering...
Social networks were first investigated in social, educational and business areas. Academic interest this field though has been growing since the mid twentieth century, given increasing interaction among people, data dissemination exchange of information. As such, development evaluation new techniques for social network analysis mining (SNAM) is a current key research area Internet services applications. Key topics include contextualized information networks, crowdsourcing crowdfunding,...
Scientific studies are usually developed by contributions from different researchers. Analyzing such collaborations is often necessary, for example, when evaluating the quality of a research group. Also, identifying new partnership possibilities within set researchers frequently desired, looking partners in foreign countries. Both analysis and identification not easy tasks, done manually. This work presents VRRC, approach visualizing recommendations people co-authorship network (i.e., graph...
