Query: How do academic topics shift across altmetric sources? A case study of
  the research area of Big Data   Taking the research area of Big Data as a case study, we propose an approach
for exploring how academic topics shift through the interactions among
audiences across different altmetric sources. Data used is obtained from Web of
Science (WoS) and Altmetric.com, with a focus on Blog, News, Policy, Wikipedia,
and Twitter. Author keywords from publications and terms from online events are
extracted as the main topics of the publications and the online discussion of
their audiences at Altmetric. Different measures are applied to determine the
(dis)similarities between the topics put forward by the publication authors and
those by the online audiences. Results show that overall there are substantial
differences between the two sets of topics around Big Data scientific research.
The main exception is Twitter, where high-frequency hashtags in tweets have a
stronger concordance with the author keywords in publications. Among the online
communities, Blogs and News show a strong similarity in the terms commonly
used, while Policy documents and Wikipedia articles exhibit the strongest
dissimilarity in considering and interpreting Big Data related research.
Specifically, the audiences not only focus on more easy-to-understand academic
topics related to social or general issues, but also extend them to a broader
range of topics in their online discussions. This study lays the foundations
for further investigations about the role of online audiences in the
transformation of academic topics across altmetric sources, and the degree of
concern and reception of scholarly contents by online communities.
