Replication is an essential requirement for scientific discovery. The current study aims to generalise and replicate 10 propositions made in previous Twitter studies using a representative dataset. Our findings suggest 6 out of 10 propositions could not be replicated due to the variations of data collection, analytic strategies employed and inconsistent measurements.
Preliminary results of the social network analysis of the Hong Kong Facebook pages sharing network collected during the “Umbrella Movement” are used to discover the communities within the network and how these communities contributed to the public opinion formation. The findings suggest that large communities of Facebook pages seem to be grouped by political ideologies and their post-sharing activities were associated with real-life public opinion.
