Análise de tendências em redes sociais acadêmicas / Trend analysis in academic social networks

Cáio César Trucolo 27 November 2015 (has links)
Conforme o volume e a diversidade de informações científicas aumentam, se torna necessário entender o que, porque e como esse aumento acontece. Estratégias e políticas públicas podem se desenvolver a partir dessas informações potencializando os serviços de educação e inovação oferecidos à sociedade. A análise de tendências é um dos passos nessa direção. Este trabalho no entanto vai além de considerar apenas o conteúdo das informações analisadas incluindo a estrutura das fontes geradoras das informações, ou seja, as redes sociais, como uma dimensão adicional para modelar e predizer tendências ao longo do tempo. Os experimentos foram realizados com os títulos das publicações de todos os doutores brasileiros da área de Ciência da Computação. Os resultados mostraram que a incorporação das medidas oriundas da análise de redes sociais reduziram os erros de predição, na média, para cerca de 18% daqueles produzidos sem a utilização destas medidas. Adicionalmente, esta incorporação permitiu que previsões mais futuras fossem realizadas sem grandes aumentos no erro destas previsões / As scientific information volume and diversity grow, the understanding of what, why and how it happens become necessary. Strategies and public politcs can be developed from these informations to power innovation and education services offered to society. Trend analysis is one of the steps in this direction. This work however goes beyond of just anlyse information content, it includes the information about the information sources structures, in other words, the social networks, as another dimension to model and predict trends through time. The experiments were made with the publication titles of all Brazilian Computer Science`s PHds. The results indicate the use o social network analysis metrics reduced the precision errors to about 18% of the errors produced without considering these metrics

Student Interactions in Edmodo Versus Facebook

January 2013 (has links)
abstract: ABSTRACT This study describes student interactions in the academic social network site Edmodo versus student interactions in Facebook. This qualitative case study relies upon four high school juniors enrolled in Advanced Placement Language and Composition who use Edmodo to complete assignments for their English class. Their experiences were gathered in an attempt to describe specific experiences in a complex system. Students were selected using an Internet Connectedness Index survey. Using a Virtual Community of Practice framework, students were asked about their experiences in Edmodo. This study concludes that Edmodo and Facebook can be compared in three categories: accessibility, functionality, and environment. Unlike Facebook, which students access regularly, students access Edmodo only to fulfill the teacher's participation expectations for the specific grade they wish to receive. Additionally, students appreciated the convenience of using Edmodo to complete assignments. The functionality of Edmodo is quite similar in layout and appearance to Facebook, yet students were unaware of the media sharing capability, wished for private messaging options, and desired the ability to tag peers for direct comment using the @ sign, all options that are available in Facebook. Students felt the environment in Edmodo could best be characterized as intellectual and academic, which some mentioned might best be used with honors or AP students. A surprising benefit of Edmodo is the lack of social cues enable students to feel free of judgment when composing writing. Some felt this allowed students to know their classmates better and share their true personae free from judgment of classmates. As a result of the case studies of four students, this study seeks to illustrate how students interact in Edmodo versus Facebook to provide a robust image of the academic social network site for teachers seeking to implement educational technology in their classes. / Dissertation/Thesis / Ed.D.
