Language in the human brain
Language is considered to be a uniquely human faculty. The different aspects of the language system, namely phonology, semantics and syntax have long been discussed with respect to their species-specificity. Syntax as the ability to process hierarchical structures appears to be specific to humans. The available neuroscientific data allow us to define the functional language network which involves Broca's area in the inferior frontal cortex and the posterior superior temporal cortex. Within this network, the posterior part of Broca's area plays a special role as it supports the processing of hierarchical syntactic structures, in particular the linguistic computation Merge which is at the root of every language. This part of Broca's area is connected to the posterior temporal cortex via a dorsally located white matter fiber tract hereby providing to structural basis for the functional interplay of these regions. lt has been shown that the maturation of this white matter pathway is directly correlated with the ability to process syntactically complex sentences during human development. Moreover, this dorsal pathway appears to be weak in the prelinguistic infant and in the non-human primate. These findings suggest that the dorsal pathway plays a crucial role in the emergence of syntax in human language.

Keynote Fire-side Chat with Barbara Grosz and Yejin Choi on
“The Trajectory of ACL and the Next 60 years”
For the 60th Anniversary of ACL 2022, we will feature a keynote fire-side chat on “The Trajectory of ACL and the Next 60 years” with two keynote talks in dialogue: Barbara Grosz and Yejin Choi followed by a moderated discussion lead by Rada Mihalcea.
Barbara J. Grosz
Harvard University SEAS
Remarks on What the Past Can Tell the Future
Research in computational linguistics and spoken language systems has made astonishing progress in the last decade. Even so, the challenge remains of achieving human-level fluent dialogue conversational capabilities beyond narrowly defined domains and tasks. Findings of earlier ACL times research on dialogue hold some lessons for breaking the “dialogue boundary” in computational linguistics yet again, if ways can be found to integrate them into deep-learning language models. These models raise some of the most serious ethical challenges of current computing research and technologies. Expanding their powers in this direction will raise more. In discussing these topics, I will raise questions for Prof. Choi and our subsequent discussion.
Barbara J. Grosz is Higgins Research Professor of Natural Sciences in the Paulson School of Engineering and Applied Sciences at Harvard University. Her contributions to AI include fundamental advances in natural-language dialogue processing and in theories of multi-agent collaboration as well as innovative uses of models developed in this research to improve healthcare coordination and science education. She co-founded Harvard's Embedded EthiCS program, which integrates teaching of ethical reasoning into core computer science courses. A member of the National Academy of Engineering, the American Philosophical Society, and the American Academy of Arts and Sciences, she is a fellow of several scientific societies and recipient of the 2009 ACM/AAAI Allen Newell Award, the 2015 IJCAI Award for Research Excellence, and the 2017 Association for Computational Linguistics Lifetime Achievement Award.

2082: An ACL Odyssey: The Dark Matter of Intelligence and Language
In this talk, I will wander around reflections on the past of ACL and speculations on the future of ACL. This talk will be purposefully imaginative and accidentally controversial, by emphasizing on the importance of deciphering the dark matter of intelligence, by arguing for embracing all the ambiguous aspects of language at all pipelines of language processing, by highlighting the counterintuitive continuum across language, knowledge, and reasoning, and by pitching the renewed importance of formalisms, algorithms, and structural inferences in the modern deep learning era.
Looking back, at the 50'th ACL, I couldn't possibly imagine that I would be one day giving this very talk. For that reason, I will also share my personal anecdotes on the lasting inspirations from the previous lifetime achievement award speeches, how I believe talent is made, not born, and the implication of that belief for promoting diversity and equity.
Yejin Choi is Brett Helsel Professor at the Paul G. Allen School of Computer Science & Engineering at the University of Washington and a senior research manager at AI2 overseeing the project Mosaic.

Keynote Panel on “Supporting Linguistic Diversity”
(chaired by Steven Bird)
Chair: Steven Bird, Charles Darwin University
Panelists and languages represented:
– Robert Jimerson, Rochester Institute of Technology (Seneca, USA)
– Fajri Koto, The University of Melbourne (Minangkabau, Indonesia)
– Heather Lent, University of Copenhagen (Creole languages)
– Teresa Lynn, Dublin City University (Irish)
– Manuel Mager, University of Stuttgart (Wixaritari, Mexico)
– Perez Ogayo, Carnegie Mellon University (Luo and Kiswahili, Kenya)
How do the tools and techniques of computational linguistics serve the full diversity of the world’s languages? In particular, how do they serve the people who are still speaking thousands of local languages, often in highly multilingual, post-colonial situations? This 60th meeting of the ACL features a special theme track on language diversity with the goal of “reflecting and stimulating discussion about how the advances in computational linguistics and natural language processing can be used for promoting language diversity”. This keynote talk-panel will showcase the special theme and identify key learnings from the conference. We hope this session will help to shape the future agenda for speech and language technologies in support of global linguistic diversity. The session will be organised around a series of questions under three headings.
Diverse Contexts. What is the situation of local languages where panel members are working? Are there multiple languages with distinct functions and ideologies? What are the local aspirations for the future of these languages. How are people advocating for language technology on the ground? How did the work begin? What does success look like?
Understanding Risks. Do the people who provide language data fully understand the ways their data might be used in future, including ways that might not be in their interest? What benefit are local participants promised in return for their participation, and do they actually receive these benefits? Are there harms that come with language standardisation? What principles of doing no harm can we adopt?
New Challenges. How can we provide benefits of text technologies without assuming language standardisation, official orthography, and monolingual usage? When working with local communities, do we always require data in exchange for technologies, or is a non-extractive NLP possible? How do we decolonise speech and language technology? At the beginning of the International Decade of Indigenous Languages 2022–2032, we ask: how do we respond as a community, and how can our field be more accessible to indigenous participation?
Bios of Panelists:
Steven Bird has spent much of his research career pursuing scalable computational methods for capturing, enriching, and analysing data from endangered languages, drawing on fieldwork in West Africa, South America, and Melanesia. Over the past 5 years he has shifted to working from the ground up with remote Aboriginal communities, supporting language learning and development in an Aboriginal ranger program, school, and arts centre.
