The Institute for Logic, Language and Computation (ILLC) has a vacancy for a postdoctoral researcher Language in Interaction. This postdoc position is part of the larger Dutch research consortium 'Language in Interaction', sponsored by a large grant from the Netherlands Organisation for Scientific Research (NWO).

Big Question 1

The big question this project addresses is how to use computational modeling to link levels of description, from neurons to cognition and behavior, in understanding the language system. We focus on the mental lexicon and aim to characterize its structure in a way that is precise and meaningful in neurobiological and (psycho)linguistic terms. Our overarching goal is to devise causal/explanatory models of the mental lexicon that can explain neural and behavioral data. This will significantly deepen our understanding of the mental lexicon, lexical access, and lexical acquisition.
The key question addressed in this project is how to learn word vector representations that encode the combinatorial properties of words required to account for complex linguistic phenomena. Current distributional semantics models typically ignore the hierarchical structure of the sentences in which they occur. They yield word representations that capture semantic similarity among concrete nouns and verbs very well, but have less to say about more abstract semantic and syntactic properties. In contrast, in all major frameworks in theoretical linguistics, the lexicon contains rich information about each word: not only about its (referential) semantics, but also about its morphosyntactic category and other combinatorial properties. In this project we study, in machine learned vector-space models, the concrete linguistic phenomena that have motivated the properties of existing linguistic formalisms (such as CCG, TAG, HPSG, CxG, Simpler Syntax, GB, MG). The project will first identify among those linguistic phenomena the ones most useful to evaluate the vector-space models. We will then work on techniques to investigate how these existing neural models deal with the phenomena in question, and, importantly, how to quantify the performance of these models on these phenomena.

Functie-eisen

The postdoctoral researcher should have:

  • a PhD degree (or equivalent) in (computational) linguistics, or another relevant field of study;
  • a strong background in syntax, formal semantics and/or parsing is required: you should be familiar with various formalisms for lexical and compositional semantics and syntax, and with a range of linguistic phenomena that motivate these formalisms;
  • knowledge of methods in distributional semantics and machine learning for Natural Language Processing is desirable, as is previous experience with vector space models of semantic compositionality;
  • an active interest in the cognitive science and neuroscience of language is essential;
  • excellent proficiency in written and spoken English.

Preference will be given to candidates whose profile stands out in comparison with international peers.

Conditions

Employment is on a full-time basis for an initial period of 18 months, after which your performance will be evaluated. On positive evaluation, the appointment will be extended by 30 months. The gross monthly salary amounts to from €3,475 until €4,757 based on a 38-hour working week and depending on relevant experience (salary scale 11). In addition you will receive an 8% holiday allowance and an 8.3% end-of-year bonus. The position is classified as Researcher, level 3 in the Dutch university job-ranking system (UFO). The Collective Labour Agreement for Dutch Universities is applicable to this position.

The University of Amsterdam is an equal opportunity employer, committed to building a culturally diverse intellectual community, and as such encourages applications from women and minorities.

Bedrijfsomschrijving

With over 5,000 employees, 30,000 students and a budget of more than 600 million euros, the University of Amsterdam (UvA) is an intellectual hub within the Netherlands. Teaching and research at the UvA are conducted within seven faculties: Humanities, Social and Behavioural Sciences, Economics and Business, Law, Science, Medicine and Dentistry. Housed on four city campuses in or near the heart of Amsterdam, where disciplines come together and interact, the faculties have close links with thousands of researchers and hundreds of institutions at home and abroad.

The UvA’s students and employees are independent thinkers, competent rebels who dare to question dogmas and aren’t satisfied with easy answers and standard solutions. To work at the UvA is to work in an independent, creative, innovative and international climate characterised by an open atmosphere and a genuine engagement with the city of Amsterdam and society.

Institute for Logic, Language and Computation

The Institute for Logic, Language and Computation (ILLC) is a research institute at the University of Amsterdam, in which researchers from the Faculty of Science and the Faculty of Humanities collaborate. Its central research area is the study of fundamental principles of encoding, transmission and comprehension of information. Research at ILLC is interdisciplinary, and aims at bringing together insights from various disciplines concerned with information and information processing, such as computational linguistics, logic, mathematics, computer science, linguistics, cognitive science, artificial intelligence and philosophy.

This postdoc position is part of the larger Dutch research consortium 'Language in Interaction', sponsored by a large grant from the Netherlands Organisation for Scientific Research (NWO). This research consortium brings together researchers from many of the excellent research groups in the Netherlands, with a research programme on the foundations of language. The goal is to understand both the universality and the variability of the human language faculty from genes to behaviour. In addition to excellence in the domain of language and related relevant fields of cognition, the consortium provides state-of-the-art research facilities and a research team with ample experience in the complex research methods that will be invoked to address the scientific questions at the highest level of methodological sophistication. These include methods from genetics, neuroimaging, computational modelling, and patient-related research.

The consortium has identified five Big Questions (BQ) that are central to our understanding of the human language faculty. We are now looking for highly motivated candidates to join the team for:

BQ1: The nature of the mental lexicon: How to bridge neurobiology and psycholinguistic theory by computational modelling?
