Spatial Role Labeling
SemEval 2013 - Task 3
http://www.cs.york.ac.uk/semeval-2013/task3/

Introduction
One of the essential functions of natural language is to talk about 
spatial relationships between objects. Linguistic constructs can express 
highly complex, relational structures of objects, spatial relations 
between them, and patterns of motion through space relative to some 
reference point. Understanding such spatial utterances is a problem in 
many areas, including robotics, navigation, traffic management, and 
query answering systems. Learning how to map this information onto a 
formal representation from text is a challenging problem. At present no 
well-defined framework for automatic spatial information extraction 
exists that can handle all of these issues. The task of spatial role 
labeling introduces an annotation scheme proposed that is 
language-independent and facilitates the application of machine learning 
techniques. The framework consists of a set of spatial roles based on 
the theory of holistic spatial semantics with the intent of covering all 
aspects of spatial concepts, including both static and dynamic spatial 
relations.

Two training corpora are available:
1. IAPR TC-12 Image Benchmark Corpus
2. The Degree Confluence Project Data
