Scope
Systems based on human-computer interactions are increasingly being
deployed. Systems can interact with humans using different devices and
sensors capturing its movements, but computers can also interact with
humans through natural language. This special session is intended to
investigate the role of Natural Language Processing for systems based
on human-computer interactions. This includes systems which can engage
a dialog with humans, answer to their questions, react to a command
in natural language and give a feedback in natural language.

Topics
Original contributions are invited.
Topics include, but are not limited to:

* Human-computer Interaction using Natural Language Understanding
* Human-computer Interaction using Semantics
* Question Answering Systems
* Dialog Systems
* Chat Bots using Natural Language Processing
* Retrieving Systems using Natural Language Processing
* Natural Language Commands Interpreters
* Natural Language Generators
* Summarization Systems
* Information Extraction Systems
* Natural Language in Knowledge Systems
