In this course we will examine how computational linguistics has been used to model language in its interactional context. We will consider particular methodological approaches and subtasks such as dialog act tagging, chatbots and
generation, social network analysis, agent-based modeling, and computational sociolinguistic case studies. We will also explore relevant background on how interaction has been studied in other areas of linguistics such as conversation
analysis, pragmatics, gesture studies, and sociophonetics, and brainstorm possible productive synergies between computational methods and these approaches. The course will conclude with final projects which either propose a study, collect
a dataset, or conduct an analysis on interactional data.

* Coronavirus Note *
remain in a difficult situation in the world. Everyone is
distracted and anxious to some degree, we're all facing
challenges across the board, and our physical and mental health
(and those of our loved ones) are the top priorities. I trust we
will all be doing our best to adapt to the cirumstances and
giving each other a lot of leeway and understanding.
this context, I am particularly willing to be understanding of
problems that arise; in exchange I ask for communication on your
part. If need be, please just let me know what's going on and
I'll do what I can to help.
Structure and Assignments
Reading, Ed Prep (weekly)
Our goal is to create a tight-knit space for discussion and intellectual engagement this quarter, so it is essential that you come to class prepared having done any assigned readings. I plan to assign on the order of 3 papers per week (less than 100 pages), so this should be manageable. I’m hoping to not overwhelm with reading so you can do it thoroughly, aiming for a relatively high level of understanding, and even allowing for time to e.g. dig deeper into sources cited by the papers, investigate methods they mention, etc.
Doing this thoughtfully and in advance of class is the most important assignment for the quarter. If you haven’t been able to keep up with reading, the quality of our discussions will suffer. Therefore I would ask you to set aside explicit time for doing readings for this class *before* Friday in each given week. Personally I will set aside several hours for myself to do (or re-do) this reading on Wednesdays. This way if something unavoidable comes up that interrupts my ability to stay on top of things, I have some buffer and can still do it before class.
Each week I will make a “questions and comments” thread on Ed. By each Thursday evening, I would like everyone to post in this thread with roughly three questions or comments about the reading. What came up for you in these readings? What was confusing? What was new to you? What was exciting? What has been missed here? What ideas for future research does this work bring up?
These can also take the form of pointers to other work. For example, if some readings we’re doing call up a connection for you to some other area of work you’re interested in, let us know about that and explain the connection. Or they could involve, e.g., looking briefly over a more foundational work cited by the current one, and let us know what relationship you found.
It is fine if these questions/comments are short; some of your questions/comments can also be in response to other peoples’ posts. Class time itself is relatively short and precious, so the point of this is to start testing the waters in advance, and build up a storehouse of paths we could choose to take when we’re together discussing.
Get stuck in, figure something out (or figure $#@%! out, if you please).
“Get stuck in” is one of my favorite British English expressions, meaning to dive into something with energy and determination, to get lost in a topic of interest, to go down a rabbit hole in a positive and productive way. When engaging with research work you will inevitably encounter things that are confusing, that you’ve never heard of, or even that seem to make no sense. You’ll run into complicated methods about which you have only the vaguest idea. I’ve often had the experience of hearing about some method or concept over and over in passing, until finally I hit a point where I say, okay, that’s it, I have to figure out what this means.
So here I’m trying to officially encode and encourage this sort of intellectual engagement. As you go through readings and discussions, keep an eye out for these moments that blend confusion/unfamiliarity with interest/curiosity. When you find one, follow it through and try to better understand something (anything) you didn’t understand as well before. As an example of something you could GSI on, imagine thinking: “I keep hearing about Markov chain Monte Carlo methods, what the heck is that anyway, and where did that name come from?”
What this follow-through looks like is of course totally up to you. This could be more reading (whether academic sources or non-), or watching (e.g. explainer YouTube videos on some concept, lecture videos from another course, a documentary on someone’s life), or other kinds of engagement. For example maybe you feel you have heard over and over about some method and really understand it conceptually, but you’ve never actually tried it, so you have a go at implementing/using it.
Once you feel you’ve figured $#@%! out to some degree, where you feel satisfied for now, post on Ed about what you did and what you learned. This doesn’t have to be an epic essay, but just a brief explanation. If you understand some concept in a way you didn’t before, try to convey that new understanding to others who might have a similar confusion.
Lead a Week (1x/quarter)
We have approximately 9 content meetings for this course, and 7 students. For the middle 7 classes, I would like one person each time to take responsibility for helping start / frame the discussion and lead throughout. We should not be having a wheel-and-spokes style discussion where one person is the center, more the idea is to have that person be responsible for reviewing the Ed questions/comments and thinking ahead of time about what directions might be most interesting to pursue in our discussion.
This course includes a final paper or project. As usual I’m very open as to what this could be. I want you to pick something that interests you and give it a good shot, presented as a pdf in ACL format, roughly 6-8 pages. I’ll ask you for proposals about halfway through the class.
- Book review - read a book in this area (I’ll provide some suggestions or you can propose your own) and write a critical commentary.
- Interactional data collection - given COVID and all, I don’t expect this will be in person, but you could imagine collecting a dataset of naturally-occurring interactions from the web, or setting up a data-collection task via crowdsourcing or other methods.
- Literature review - dive deeper into an area we covered, or another area of your interest related to computation and interaction that we didn’t get to.
- Replication - replicate an existing interactional paper from the literature. See if you can find any ways to go beyond the original analysis. Document the challenges you encountered along the way.
- Propose future work - develop a research question and design a methodology by which it could plausibly be solved.
- Your own idea!
a fan of grades, to be honest. Research has shown that
traditional numerical/letter grades decrease
intrinsic motivation and joy for learning, can
undermine performance, and are
potentially riddled with implicit bias. For more reading on
Therefore, grades in this course are based predominantly upon midterm and final self-evaluations. The core evaluation metric I will ask you to consider is engagement. Did you keep up with readings and other work for the course? Did you put energy and effort into learning about this topic and engaging with both the material and your fellow students? Did you follow through on the agreements we set out at the first class?
Here are my proposals for some agreements on how we conduct ourselves. I am very open to adding more, or editing these, or even removing them.
Listening and Mutual Respect
Hopefully this goes mostly without saying, but I propose we agree to strive to treat everyone else in the class with kindness and respect, including in particular an attentiveness to the value of each person’s contributions to our discussions. Assume your colleagues have interesting and useful things to say, because they almost certainly do!
A space of intellectual discussion will inevitably lead to disagreements and conflicting ideas. I propose we agree to be open to such disagreement and welcome its possible presence.
Non-Anonymity and Presence
I propose that we stand behind our contributions to this course and engage directly and presently. For me that means at least posting on Ed non-anonymously, and having your video on when on Zoom when possible.
A flipside of this is if we are to have a trusted and trusting environment, I propose that we agree to have discretion in what is shared beyond the confines of the class. A seminar is ultimately about generating public-facing research, so we can’t have true confidentiality, but I also think we should encourage this to be a space where people feel free and open to share both their intellectual contributions and potentially personal experiences if relevant. The idea: shared personal experiences are confidential; research-based content is not. You can share ideas generated in the course, but not necessarily the motivations (personal, story-based).
It is very easy to be distracted in our modern age. I am deeply guilty of giving into distractions more than I would like. I propose that during the brief window of the seminar, we take active steps to preserve our attention for one another. Beyond an agreement to simply commit our attention, the first thing that jumps out to me would be an agreement to not check email during class, or to do anything on your computer/phone unrelated to the class. This is especially difficult during Zoom times, I know. On the flipside, I propose that especially during Zoom times we do not consider e.g. food and drink to be distractions, I think having your coffee with you or whatever can actually help focus. As a part of this we will also have a break midway through every class.
