As cinco pontes são fundamentais na manutenção do fluxo de informação que parte das sete comunidades principais para regiões mais periféricas do circuito de REA. Seis comunidades e quatro pontes estão localizadas no Norte Global e uma comunidade e uma ponte encontram-se no Sul Global</span></span><span style="background: transparent;">.</span></span></span></p><p style="margin-bottom: 0cm;" align="justify"><span style="color: #000000;"><span style="font-family: Liberation Sans, sans-serif;"><strong><span style="background: transparent;">PALAVRAS</span></strong><strong><span style="background: transparent;">-</span></strong><strong><span style="background: transparent;">CHAVE</span></strong><span style="background: transparent;">: </span><span style="background: transparent;">comunidades e atores de Recursos</span><span style="background: transparent;">Educacionais Abertos (REA); </span><span style="background: transparent;">T</span><span style="font-style: normal;"><span style="background: transparent;">witter</span></span><span style="background: transparent;">; análise de redes sociais; grafos de redes</span><span style="background: transparent;">.</span></span></span></p><p style="margin-bottom: 0cm; font-weight: normal; page-break-before: auto;" align="justify">&nbsp;</p><p style="margin-bottom: 0cm; page-break-before: auto;" align="justify"><span style="color: #000000;"><span style="font-family: Liberation Sans, sans-serif;"><strong><span style="background: transparent;">ABSTRACT</span></strong><span style="font-weight: normal;"><span style="background: transparent;">:</span></span><span lang="en-US"><span style="background: transparent;">This article aims at identifying </span></span><span lang="en-US"><span style="background: transparent;">the interaction dynamics of </span></span><span lang="en-US"><span style="background: transparent;">Open Educational Resources (OER)</span></span><span lang="en-US"><span style="background: transparent;"> global communities </span></span><span lang="en-US"><span style="background: transparent;">on Twitter, from 2012 to 2017.</span></span><span lang="en-US"><span style="background: transparent;"> Our purpose is to identify, by using</span></span><span lang="en-US"><span style="background: transparent;"> Analysis of Social Networks </span></span><span lang="en-US"><span style="background: transparent;">(</span></span><span lang="en-US"><span style="background: transparent;">SCOTT, 2012;</span></span><span lang="en-US"><span style="background: transparent;"> RECUERO, 2014</span></span><span lang="en-US"><span style="background: transparent;">), </span></span><span lang="en-US"><span style="background: transparent;">the best positioned nodes </span></span><span lang="en-US"><span style="background: transparent;">that serve as bridges for information exchange among central and peripheral OER communities within the </span></span><span lang="en-US"><span style="background: transparent;">network.</span></span><span lang="en-US"><span style="background: transparent;"> Three graphs </span></span><span lang="en-US"><span style="background: transparent;">based on </span></span><span lang="en-US"><span style="background: transparent;">metrics of</span></span><span lang="en-US"><span style="background: transparent;"> betweenness</span></span><span lang="en-US"><span style="background: transparent;"> centrality, indegree and outdegree centrality</span></span><span lang="en-US"><span style="background: transparent;">are produced.
