SensePlace2 is a geovisual analytics application that forages place-time-attribute information from the Twitterverse and supports crisis management through visually-enabled sensemaking with the information derived.
To help researchers investigate relation extraction, we’re releasing a human-judged dataset of two relations about public figures on Wikipedia: nearly 10,000 examples of “place of birth”, and over 40,000 examples of “attended or graduated from an institution”. Each of these was judged by at least 5 raters, and can be used to train or evaluate relation extraction systems. We also plan to release more relations of new types in the coming months.
