These are the proceedings of the third Linguistic and Cognitive Approaches to
Dialog Agents (LaCATODA 2018), which was held on July 13, 2018 in Stockholm,
Sweden. The workshop was a part of the 27th International Joint Conference on
Artificial Intelligence (IJCAI 2018) colocated with ECAI 2018, the 23rd European
Conference on Artificial Intelligence. Bothe conferences were held under the
umbrella of Federated AI Meeting (FAIM 2018), the biggest AI joint conference
so far. Fourteen papers were submitted to the workshop of which eight was
accepted to be presented during the workshop. The submissions were reviewed
by three (at least two) members of the program committee.
This workshop was the fourth edition of the LaCATODA series. The two first
editions were organized as symposia of the AISB/IACAP conferences in United
Kingdom: the first one in 2010 in Leicester, and the second one in Birmingham.
The third edition was co-located with the prestigious IJCAI conference in
Melbourne, 2017. We would like to thank all authors who submitted papers, and
the program committee members for their efforts.
