Atila 2011

1-2 December 2011 / Antwerp, Hyllit Hotel

We are pleased to announce that this year's edition of Atila will be held in the exquisite Hyllit Hotel  in Antwerp on Thursday 1 and Friday 2 December 2011. Atila is the annual two-day research meeting for the members of the Computational Linguistics groups of the University of Antwerp (CLiPS), Ghent (LT3) and Tilburg (ILK). Our 2011 invited speaker will be Afra Alishahi (previously Universität des Saarlandes, now Tilburg University), who will present her work on Computational Psycholinguistics and Language Acquisition. A novelty this year be will our welcoming a number of newcomers from the University of Nijmegen, following Antal's recent move.


Invited Speaker

On Thurday 1 December, Dr. Afra Alishahi (previously Universität des Saarlandes, now Tilburg University) will give an invited talk about her recent work in Computational Psycholinguistics and Language Acquisition. Her talk is entitled:

A Bayesian account of the acquisition of abstract argument structure constructions

Abstract - Developing computational algorithms that capture the complex structure of natural languages is an open problem. In particular, learning the abstract properties of language only from usage data without built-inknowledge of language structure remains a challenge. We have developed a Bayesian model of the acquisition and use of verb argument structure from child-directed data. In our model, the general constructions of language (such as transitive and intransitive) are viewed as a probability distribution over the syntactic and semantic features, e.g., the semantic properties of the verb and its arguments, and their relative word order in an utterance. Constructions are learned through clustering similar verb usages. Language use, on the other hand, is modeled as a Bayesian prediction problem, where the missing features in a usage are predicted based on the available parts and the acquired constructions (e.g., in sentence production, the best syntactic pattern for an utterance is predicted from the available semantic information). The model can successfully learn the common constructions of language, and its behaviour shows similarities to actual child data, both in sentence production and comprehension. Moreover, the acquired knowledge of language in this model is robust yet flexible, and many general patterns of behaviour that are observed in children can be simulated and explained by this approach.

Program

(Note: for all regular talks we anticipate a duration of 15 minutes, with 5 minutes for questions afterwards.)
