----------------------------------------------------------------FINAL CALL FOR 
PAPERS
----------------------------------------------------------------

First International Workshop on Spatial Language Understanding (SpLU-2018) at 
NAACL-HLT 2018, June 6, New Orleans, Louisiana, USA.

Website: https://spatial-language.github.io/

---------------------------------------------------------------
AIM AND SCOPE
---------------------------------------------------------------

One of the essential functions of natural language is to express spatial 
relationships between objects. Linguistic constructs can encode highly 
complex, relational structures of objects, spatial relations between them, 
and patterns of motion through space relative to some reference point. 
Spatial language understanding is useful in many areas of research endeavors 
relating to and/or making use of human language, including robotics, 
navigation, geographic information systems, traffic management, natural 
language understanding and translation, and query answering systems.

Standardizing semantically specialized linguistic tasks related to spatial 
language especially seems challenging as it is hard to obtain an agreeable 
set of concepts, relationships and a formal spatial meaning representation 
that is domain independent. This has made research results on spatial 
language learning and reasoning diverse, task-specific and, to some extent, 
not comparable. While formal meaning representation is a general issue for 
language understanding, formalizing spatial concepts and building formal 
reasoning models based on those constitute challenging research problems with 
a wealth of prior foundational research that can be exploited and linked to 
language understanding. Existing qualitative and quantitative representation 
and reasoning models can be used for investigation of interoperabiltiy of 
machine learning and reasoning over spatial semantics. Research endeavors in 
this area could provide insights into many challenges of language 
understanding in general. Spatial semantics is also very well-connected and 
relevant to visualization of natural language, central to dealing with 
configurations in the physical world and motivating a combination of vision 
and language for richer spatial understanding.

This workshop highlights some of the above aspects of computational spatial 
language understanding including the following four areas: Spatial Language 
Meaning Representation (Continuous, Symbolic), Spatial Language Learning, 
Spatial Language Reasoning, and Combining Vision and Language for Spatial 
Understanding. The goal of the workshop is to initiate discussions across 
fields dealing with spatial language along with other modalities. The desired 
outcome is identification of shared as well as unique challenges, problems 
and future directions across the fields and various application domains 
related to spatial language understanding.
