Postdoctoral Researcher in Computational linguistics focused on multimodal coreference

Posted on: September 28, 2023

The University of Gothenburg tackles society’s challenges with diverse knowledge. 56 000 students and 6 600 employees make the university a large and inspiring place to work and study. Strong research and attractive study programmes attract scientists and students from around the world. With new knowledge and new perspectives, the University contributes to a better future.

The Department of Philosophy, Linguistics and Theory of Science at the Faculty of Humanities has around 100 employees and a teaching volume that includes around 350 full-year students. Many large national and international research projects are underway here. Our education includes philosophy, logic, linguistics, language technology, theory of science and liberal arts. The department also conducts research training and development work in these areas.

The Centre for Linguistic Theory and Studies in Probability (CLASP) is based in FLoV at the University of Gothenburg, and is funded by a 10-year grant from the Swedish Research Council (2015-2025). CLASP is devoted to research and advanced training in the application of probabilistic modeling and machine learning methods to core issues in linguistic theory and cognition. It also addresses topics in dialogue and linguistic interaction. For a description of CLASP, see https://www.gu.se/en/clasp.

Subject area

Computational linguistics

Subject area description

The candidate will carry out their research at CLASP, within a project interested in multimodal coreference resolution.

The overarching goal of the project is to construct a multimodal coreference resolution system (MCRS) that uses text and visual input. We will experiment with crowdsourcing methods to annotate training and test corpora. MCRS will be lightweight in that it will use relatively small amounts of data for supervised learning. It will be trainable in a comparatively short period of time. We will build MCRS on top of existing generic deep learning systems, like multimodal BERT, rather than constructing a large, complex special purpose device. MCRS will be a genuine coreference resolution system. It will seek to determine the specific antecedents, and the graphic object to which an anaphoric expression refers. Its performance will be evaluated on the accuracy with which it performs this task, rather than by its success in returning a ranked class of candidates that includes the ground truth antecedent. The project will explore different ways of integrating visual and linguistic representations in integrated embeddings, and we will determine which ones are most efficient in supporting MCR.

Job assignments

The expected candidate is expected to:

  • Collect, compile and process coreference resolution corpora from different genres, domains and methodologies
  • Develop and evaluate coreference resolution models
  • Carry out evaluations of multimodal systems, i.e., images and text (in particular for reference and discourse phenomena)
  • Develop a multimodal coreference resolution system that uses text and visual input The expected duration of the assignment is 2 years, with possibility of 1-year extension.

The research will be conducted in English.

Apart from research, supplementary duties may include mentoring graduate students, course design, and/or teaching-related activities. These duties are not mandatory and will not exceed 20% of the position’s responsibilities.

The holder of the position is expected to carry out her/his research in Gothenburg and to actively participate in the research group's workshops, seminars, and conferences.

Eligibility

Eligible for a postdoctoral position are those with a PhD or other foreign degree that is deemed equivalent to PhD. The subject of the doctoral thesis should be in a research area relevant to the specific subject description above. Since the postdoctoral position is intended to give junior researchers the opportunity to establish themselves in the field, we aim to employ applicants that graduated with PhDs within 3 years of the application deadline.

Please note that qualifications for postdoctoral appointments are described in more detail at: Avtal om tidsbegränsning anställning som postdoktor (arbetsgivarverket.se)

Assessment

Candidates should have experience with machine learning including deep learning and neural networks, preferably with a background in mainstream natural language processing tasks and methods (e.g., language modeling, parsing, coreference, machine translation, discourse parsing, etc). Interest in the cognitive processes/models behind human language processing and understanding is a key advantage for the position. Experience with psycholinguistic methods focused on designing and running traditional sentence processing methodologies (eye-tracking, pace reading, judgement studies and cloze tests, spacebar reaction time, etc.) is also desirable.

Scientific proficiency is the most important criterion for assessment, and special attention will be given to the applicant’s PhD thesis and other publications. Documented good interpersonal skills, good skills in terms of planning and organizing research, and good skills in communicating research results is also meritorious.

The recruitment process may include interviews (possibly by video link) and contacting references.
