News

2017-02-19: Our demonstration paper EVELIN: Exploration of Event and Entity Links in Implicit Networks was accepted for presentation at the 26th World Wide Web Conference (WWW'17), April 3-7, Perth, Australia. The online interface of EVELIN for browsing the Wikipedia LOAD network is now public.

2016-11-29: We updated the online news citation network. It now includes many more news articles from more outlets (297,192 edges and 209,207 nodes), ranging from June 2014 to November 2016.

2016-11-22: We updated the LOAD entity network resource page with more data sets, including a smaller US Civil War graph extracted from a subset of Wikipedia articles. The LOAD graphs are now also available in edge list format.

2016-09-26: Our paper Refining Imprecise Spatio-temporal Events: A Network-based Approach was accepted for presentation at the 10th Workshop on Geographic Information Retrieval (GIR'16) at SIGSPATIAL'16, October 31, San Francisco, USA.The data is available for download.
