SpaceRef: A corpus of street-level geographic descriptions

This article describes SPACEREF, a corpus of street-level geographic descriptions. Pedestrians are walking a route in a real urban environment, describing their actions. Their position is automatically logged, their speech is manually transcribed, and their references to objects are manually annotated with respect to a crowdsourced geographic database. We describe how the data was collected and annotated, and how it has been used in the context of creating resources for an automatic pedestrian navigation system.
