SemEval-2013 Task 3: Spatial Role Labeling

Many NLP applications require information about locations of objects referenced in text, or relations between them in space. For example, the phrase a book on the desk contains information about the location of the object book, as trajector, with respect to another object desk, as landmark. Spatial Role Labeling (SpRL) is an evaluation task in the information extraction domain which sets a goal to automatically process text and identify objects of spatial scenes and relations between them. This paper describes the task in Semantic Evaluations 2013, annotation schema, corpora, participants, methods and results obtained by the participants.
