Annotating If the Authors of a Tweet are Located at the Locations They Tweet About

Abstract

The locations in a tweet do not always indicate spatial information involving the author of the tweet. In this paper, we investigate whether authors are located or not located in the locations they tweet about, and temporally anchor this spatial information in the tweet timestamp. Specifically, we work with temporal tags centred around the tweet timestamp: longer than 24 hours before or after tweeting, within 24 hours before or after tweeting, and at the time of tweeting. We introduce a corpus of 1,200 location mentions from 1,062 tweets, discuss several annotation samples, and analyze annotator disagreements.
