  Social media and user-generated content (UGC) have become increasingly
important features of journalistic work in a number of different ways. However,
the growth of misinformation means that news organisations have had devote more
and more resources to determining its veracity and to publishing corrections if
it is found to be misleading. In this work, we present the results of
interviews with eight members of fact-checking teams from two organisations.
Team members described their fact-checking processes and the challenges they
currently face in completing a fact-check in a robust and timely way. The
former reveals, inter alia, significant differences in fact-checking practices
and the role played by collaboration between team members. We conclude with a
discussion of the implications for the development and application of
computational tools, including where computational tool support is currently
lacking and the importance of being able to accommodate different fact-checking
practices.
