These are the proceedings of the seventh Linguistic and Cognitive Approaches to Dialog Agents (LaCATODA 2021), which was held online on August 21, 2021 as a part of the 30th International Joint Conference on Artificial Intelligence (IJCAI 2021). Nine papers were submitted to the workshop of which six were accepted (four long and two short) to be presented during the workshop. The submissions were reviewed by at least two members of the program committee. One paper has been withdrawn therefore we decided to organize an additional invited event — except an invited keynote, we also organized an invited lecture as a mini tutorial for all participants interested in more practical side of building dialog systems.
This workshop was the seventh 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. From the third edition we have been co-located with the prestigious IJCAI conference: in Melbourne (2017), Stockholm (2018), Macao (2019). Due to the COVID-19 pandemic, 2020 and 2021 workshops were moved from Kyoto and Montreal to online venues.
We would like to thank all authors who submitted papers, and the program committee members for their efforts.
