“…Note that the geographical distribution of the volunteer and paid workers was very different; the volunteer workers came predominantly from the countries with an active public discussion of climate change on Twitter and a high level of Twitter penetration. For example, the daily number of English language tweets originating from the U.S. is~30 times higher than those for India, but this number is only three times higher than those from the U.K. [2]. We therefore speculate that the main reason for the low quality of India data was insufficient familiarity of the workers with climate change discourse in general.…”

“…Twitter data was originally collected for a project on online discussions of climate change, and early results were covered in [2]. Software was developed to systematically poll the Twitter social networking site for the terms "climate change" and "global warming", which resulted in over 2 million tweets collected; after filtering as described in [7], this dataset was reduced to 1.3 million georeferenced tweets.…”

“…Kirilenko and Stepchenkova [2] used a 1-million sample of tweets to research geographical variations in climate change discourse worldwide. Cody et al [3] analyzed 1.5 million tweets containing the words "climate" to explore temporal changes in sentiment (described in the paper as "a tool to measure happiness") expressed by the people in relation to climate change.…”

Crowdsourcing Analysis of Twitter Data on Climate Change: Paid Workers vs. Volunteers

Web based crowdsourcing has become an important method of environmental data processing. Two alternatives are widely used today by researchers in various fields: paid data processing mediated by for-profit businesses such as Amazon's Mechanical Turk, and volunteer data processing conducted by amateur citizen-scientists. While the first option delivers results much faster, it is not quite clear how it compares with volunteer processing in terms of quality. This study compares volunteer and paid processing of social media data originating from climate change discussions on Twitter. The same sample of Twitter messages discussing climate change was offered for processing to the volunteer workers through the Climate Tweet project, and to the paid workers through the Amazon MTurk platform. We found that paid crowdsourcing required the employment of a high redundancy data processing design to obtain quality that was comparable with volunteered processing. Among the methods applied to improve data processing accuracy, limiting the geographical locations of the paid workers appeared the most productive. Conversely, we did not find significant geographical differences in the accuracy of data processed by volunteer workers. We suggest that the main driver of the found pattern is the differences in familiarity of the paid workers with the research topic.

“…Sabe-se que a realização de eventos internacionais, as agendas intergovernamentais, as publicações de lideranças políticas e/ou pessoas famosas e os eventos meteorológicos extremos proporcionam um aumento nas abordagens não só na mídia tradicional como também nas referências ao tema nas redes sociais (Kirilenko & Stepchenkova, 2014;Pearce et al, 2014;Cody et al, 2015). está acontecendo?".…”

Artigo recebido em 30 de outubro de 2016, versão final aceita em 1 de fevereiro de 2017. RESUMO:A 21ª Conferência das Partes (COP21) da Convenção-Quadro das Nações Unidas sobre Mudanças no Clima foi apontada como a mais promissora reunião para um acordo global de combate aos efeitos das mudanças climáticas e redução da emissão de gases de efeito estufa. Este artigo analisa a comunicação sobre as mudanças climáticas no ambiente online durante o período da Conferência. Os temas debatidos nas redes sociais são suscetíveis a afetar o debate de forma ampla e trazem importantes informações a respeito da opinião pública e de percepções sobre as mudanças climáticas (Williams et al., 2015). Para este fim, o trabalho foca-se na popular rede social Twitter, que tem sido apontada como um termômetro da percepção pública (Brown & Wake, 2015). O Twitter tem mais de 310 milhões de utilizadores ativos por mês, dos quais 79% estão fora dos Estados Unidos da América, o que possibilita analisar outros contextos e fomentar a investigação em idiomas sub investigados, como o espanhol e o português. Lança-se um primeiro olhar sobre os usos e conteúdos publicados no Twitter nas línguas mencionadas visando responder às seguintes questões: Que tipo de conteúdos são mais populares no Twitter sobre mudanças climáticas? Qual a linguagem (palavras e nomes) utilizada para se debater o tema? Até que ponto é que a mídia tradicional é referência relevante no contexto da comunicação sobre as mudanças climáticas na rede social? Quem são os atores que formam esta rede e quais são os mais influentes? Conclui-se, entre outros aspectos, que entre os atores da rede se destacam diversos políticos e que a mídia é referência importante de informação nesta rede social. Nos dados em língua portuguesa, constatou-se um nível de atividade muito elevado dos cidadãos, que dominaram a produção de conteúdos sobre a COP21.Palavras-chave: mudanças climáticas; comunicação; redes sociais; Twitter. ABSTRACT:The 21st Conference of Parties (COP21) of the United Nations Framework Convention on Climate Change was identified as the most promising summit for a global agreement aiming to combat the effects of climate change and to reduce emissions of greenhouse gases. This article analyses online communications about climate change during the Conference. The subjects discussed in social networks are likely to affect public debates and provide important information regarding public opinion and perceptions of climate change (Williams et

Motivated reasoning and climate change: Comparing news sources, politicization, intensification, and qualification in denier versus believer subreddit comments

Motivated reasoning explains how climate change deniers can maintain their beliefs in the face of disconfirming evidence, suggesting that, compared to believers, the online comments of climate change deniers are more likely to (a) reference independent and social media websites advocating ideologically congruent positions, (b) politicize the issue, and (c) use intensifiers (e.g., definitely, undoubtedly). Automated text analysis of 156,844 comments from subreddit communities with opposing perspectives on climate change identified the internet domains associated with hyperlinks and the frequencies of political terms and intensifiers in user comments. Results were consistent with motivated reasoning by climate change deniers. In addition, climate change believers were more likely than deniers to use qualifiers in their comments.
