Scottish Independence Referendum on Twitter
We present a new tool that monitors discussions on Twitter about the Scottish Independence Referendum.
Sensing User Generated Input for Improved Media Discovery and Experience
SocialSensor is developing a new framework to enable real-time multimedia indexing and search from the online social networks. The European Union funded FP7 project moves beyond conventional text-based indexing and retrieval models by mining and aggregating user inputs and content over multiple social media sites.
Social indexing will incorporate information about the structure and activity of the users' social network directly into the multimedia analysis and search process.
The SocialSensor News prototype is a tool designed for both news professionals, such as journalists and editors, and for casual news readers.
The system identifies key influencers in social networks who are active in sharing news or have demonstrated expertise in a particular field of interest. Information and data from these "news hounds" ensure that topics, trends and trust scores are useful for professional and general news users alike. Interfaces have been developed for web, mobile and tablet.
Our key contributions to this project include:
Topic detection - we developed novel methods to discover and track news stories as they break and spread across social networks. Our "BNgram" method finds words or phrases that show a sudden increase in popularity, which typically shows a response to a real-world event. Our software can then combine these messages to form coherent topics, complete with a human-readable label as a headline.
News hounds - we developed novel methods to automatically identify active and influential users of social networks with an interest in sharing the news. This includes journalists, bloggers, politicians and other opinion formers. Such users often forward up-to-date messages from eye-witnesses of major events, ensuring that a wide range of current information is available.
Context aware search - we have researched a number of methods to enhance search by taking account of the wider context that the user is in.
Evaluation - we have been active in the systematic evaluation of all aspects of the system, including user-centred `simulated task' studies and organizing an international evaluation competition in the area of news-focussed topic detection.
We have recently developed a system that monitors discussions on Twitter about the Scottish Independence referendum.
