Determining the Presence of Political Parties in Social Circles

AAAI Conferences

We derive the political climate of the social circles of Twitter users using a weakly-supervised approach. By applying random walks over a sub-sample of Twitter's social graph we infer a distribution indicating the presence of eight Flemish political parties in users' social circles in the months before the 2014 elections. The graph structure is induced through a combination of connection and retweet features and combines information of over a million tweets and 14 million follower connections. We solely exploit the social graph structure and do not rely on tweet content. For validation we compare the affiliation of politically active Twitter users with the most-influential party in their network. On a validation set of around 700 politically active individuals we achieve F_1 scores of 0.85 and greater. We asked the Twitter community to evaluate our classification performance. More than half of the 2258 users who responded reported a score higher than 60 out of 100.

Learning to Discover Social Circles in Ego Networks

Neural Information Processing Systems

Our personal social networks are big and cluttered, and currently there is no good way to organize them. Social networking sites allow users to manually categorize their friends into social circles (e.g. We define a novel machine learning task of identifying users' social circles. We pose the problem as a node clustering problem on a user's ego-network, a network of connections between her friends. We develop a model for detecting circles that combines network structure as well as user profile information.

Glad's plastic containers have long been a friend to lunch packers and leftover enthusiasts everywhere. But, as several have recently discovered thanks to a picture on social media, the iconic blue-lidded containers are actually way more convenient than most people previously realized.

Someone please tell me I'm not the only one who didn't know this," someone responded on Facebook. Apparently she wasn't, because the picture has amassed quite a following – liked over 14K times and shared more than 2K times.

Odd radio circle in space may be supermassive black hole merger

New Scientist

A mysterious circle of radio waves has been detected, the fifth odd radio circle (ORC) ever spotted, but its cause is still unclear. It could simply be the side view of a galaxy with an active black hole at its centre, although it might be the result of a supermassive black hole merger. In 2020, Ray Norris at Western Sydney University, Australia, and his colleagues found four strange circles made from radio waves in space.

'Ancient' Aberdeenshire stone circle found to be replica

BBC News

An Aberdeenshire stone circle initially thought to be thousands of years old has been identified as a modern replica. An investigation into the site at the parish of Leochel-Cushnie found the stones to be about 20 years old. It was originally thought to be the site of another recumbent stone circle - until the person who built it came forward. The findings sparked excitement among experts and were widely reported. Further archaeological analysis of the stones was being conducted when a former owner of the farm contacted Mr Welfare to say they had built the stone circle in the 1990s.
