NoD: Network of the Day, Hochschulwettbewerb 2014

Network of the Day (NoD) is a project carried out in the framework of “Hochschulwettbewerbs 2014, Mehr als Bits und Bytes”. As online news, blogs, and social media contents are becoming extremely popular by internet users, special effort should be exerted in the processing, analysing and visualizing important facts and events. The data presentation fuses German Twitter data and a social relation network extracted from German online news. Such fusion allows for comparative analysis of the two types of media. The system enables users to explore relationships between named entities, and to investigate events as they develop over time. Cooperative tagging of relationships is enabled through the active involvement of users. The system is available online for a broad user audience. A live demo and a more detailed description of the project can be found here.
