Just published: McCarthy and Pater’s Harmonic Grammar and Harmonic Serialism

image001

John McCarthy and Joe Pater’s edited collection, Harmonic Grammar and Harmonic Serialism, has just been published by Equinox Press. Many of the authors are alumni of our PhD program (Elfner, Jesney, Kimper, Moore-Cantwell, Pruitt, Staubs and Wolf). The research was supported by two NSF grants held by McCarthy and Pater.

Bridging computational & psycholinguistic approaches to meaning

CSLI in Stanford sent out a call for posters for a workshop on bridging computational and psycholinguistic approaches to the study of meaning. The deadline for submitting abstracts is November 1st. From the workshop description:

In recent years, the study of meaning has seen rapid advances in two still largely disconnected areas: probabilistic semantics/pragmatics  and psycholinguistics. Both of these areas have drawn on traditional formal semantics/pragmatics for inspiration, especially Grice’s original insights, while adding other perspectives from cognitive science. On the one hand, the burgeoning field of probabilistic pragmatics has been hugely successful in modeling a wide variety of phenomena as the outcome of iterated Bayesian reasoning between speakers and listeners — including scalar implicature, M-implicature, figurative meaning, pronoun resolution; as well as the interpretation of gradable predicates, quantifiers, spatial relations, generics, and referring expressions On the other hand, psycholinguistic research in experimental semantics and pragmatics is painting an ever more complex picture of the interactions of multiple factors in the computation of speaker meaning, including literal meaning, perspective-taking, prosody, availability of alternatives, the Question Under Discussion, world knowledge, and speaker-specific idiosyncrasies.

New Conference on Computational Approaches in Linguistics

We are planning a new conference on computational modeling in linguistics, whose first meeting is tentatively scheduled to take place at UMass in Fall 2017. We have been hosting a discussion about various aspects of the plans for this conference on the UMass Computational Phonology Lab blog page and would love to get more input from linguists about our plans. We want to gather as much information as we can about how best to realize our goals for this conference and make it as accessible and useful to linguists as possible!

Please follow the link to our lab blog for full details and discussion, but to summarize, this conference is intended for linguists and cognitive scientists using computational and mathematical approaches to study the human language faculty.  We’re particularly interested in input from linguists on the following key aspects of the current plans:

  • The short-term and long-term co-location/venue possibilities
  • The name and ideal scope and target audience for the conference
  • The tentative plan to have short paper (6-8pp) submissions (rather than abstract submissions). Please go to this post for discussion and comments on this aspect of the current plans.

We’ve had quite a bit of discussion on our blog already, primarily from potential participants of this conference who also regularly attend workshops and/or conferences affiliated with the ACL. This discussion has been very useful, but the conference would ideally be accessible and appealing to a broader community of linguists than is currently represented in the discussion. So we are looking for additional input from linguists who are potentially interested in this new conference, but who do not generally attend ACL – we’d be very grateful to hear about the kinds of considerations that could increase or decrease the chances phonologists and other linguists would attend and/or submit their best work to this conference.

Many thanks!

Blodgett, Green & O’Connor in ScienceDaily

Sources: ScienceDailyUMass Amherst, arXiv.org. As reported earlier, Lisa Green and Brendan O’Connor collaborated with doctoral student Su Lin Blodgett on a case study of African American English in on-line Twitter conversations. The authors have created what they believe to be the largest data set of African American English to date, examining 59 million tweets from 2.8 million users. Their goal is to characterize and identify dialects, and to ultimately create language technology that is adapted to African American English.

Work on AAE and Twitter published at EMNLP 2016

A CS+Linguistics group of collaborators — Su Lin Blodgett (CS), Lisa Green (Linguistics), and Brendan O’Connor (CS) — have published a paper on African-American English and Twitter. It will be presented at Empirical Methods in Natural Language Processing this November, and published in the Proceedings of EMNLP. A preprint is linked below.

Demographic Dialectal Variation in Social Media: A Case Study of African-American English

Abstract:
Though dialectal language is increasingly abundant on social media, few resources exist for developing NLP tools to handle such language. We conduct a case study of dialectal language in online conversational text by investigating African-American English (AAE) on Twitter. We propose a distantly supervised model to identify AAE-like language from demographics associated with geo-located messages, and we verify that this language follows well-known AAE linguistic phenomena. In addition, we analyze the quality of existing language identification and dependency parsing tools on AAE-like text, demonstrating that they perform poorly on such text compared to text associated with white speakers. We also provide an ensemble classifier for language identification which eliminates this disparity and release a new corpus of tweets containing AAE-like language.

Aynat Rubinstein assistant professor at the Hebrew University

Aynat Rubinstein (2012 UMass PhD) has just started her new position as assistant professor (tenure track) at the Hebrew University of Jerusalem, with a joint appointment in the Hebrew Language and Linguistics Departments. Aynat combines theoretical work in natural language semantics and its interfaces with an experimental perspective that includes corpus creation and annotation, corpus mining, and natural language processing. Her work on modality has been internationally recognized, most recently by being the (sole) invited speaker at next year’s workshop “Towards an Ontology of Modal Flavors” held as part of the 2017 annual meeting of the German Linguistic Society in Saarbrücken. Last February, Aynat organized a Winter School on Language Documentation and Linguistic Fieldwork at the Hebrew University. The winter school included mentorships for fieldwork projects on Modern Hebrew, Palestinian Arabic dialects, Judeo-Arabic dialects, Aramaic dialects, Amharic, Nuer, Yiddish, Judeo-Spanish (Ladino), Jewish Malayalam, and other languages of Israel.

Alex Nazarov defends, goes to Harvard

On July 26th, Alex Nazarov successfully defended his dissertation “Extending Hidden Structure Learning: Features, Opacity, and Exceptions”. The committee consisted of Gaja Jarosz (co-chair), John McCarthy, Joe Pater (co-chair), David Smith (Computer Science) and Kristine Yu. He’s taking up a lectureship at Harvard this academic year. Congratulations Alex!

Deniz Özy?ld?z awarded EACL grant to attend ESSLLI 2016 at Bolzano

Deniz Özy?ld?z has been awarded a grant from the European Association of Computational Linguistics to attend the 28th European Summer School in Logic, Language, and Information (ESSLLI) at Bolzano (Italy). Deniz will also present a paper on knowledge reports without truth at the ESSLLI Student Session.
