### Research engineer position at Aix Marseille University (France) – ANR

### Data and software support for next-generation word sense induction


* Starting date: June 2022 (flexible)

* Application deadline: May 2, 2022 by email to carlos.ramisch [AT]

* Location: LIS lab , TALEP team
, Aix Marseille University
, Luminy campus
<https://sciences.univ-amu.fr/sites-geographiques/site-luminy>, Marseille

* Remuneration (CDD): 1,600? to 2,000?, depending on experience

SELEXINI is a research project whose goal is to develop
next-generation lexicon
induction methods for NLP. The induced lexicons will not only cluster word
usages according to their senses, but also contain multiword expressions,
frames, argumental structure, generated definitions, etc. The developed
sense and frame induction methods will build upon large pre-trained
language models (e.g. FlauBERT, CamemBERT) and existing lexical resources
(French Wiktionary).

We are currently looking for an engineer whose mission will be to put
in place the initial infra-structure of the project. This mission will have
five phases:

(1) corpus curation: gather, pre-process and format a large French
corpus from diverse written registers;

(2) preprocessing: apply in-house tools to (deep) parse, identify
multiword expressions, etc. on the corpus;

(3) pre-lexicon extraction: extract and structure information from
French Wiktionary (e.g. using DBNary);

(4) language model adaptation: additional tuning of pre-trained
language models on target corpora;

(5) alignment: link corpus occurrences to Wiktionary entries, both for
words and multiword expressions.

Dealing with such a billion-word corpus will require developing
strategies to speed up processing via parallel processing, e.g. to apply
pre-processing tools to the corpus. Therefore, the recruited person will
have access to the LIS cluster and to dedicated processing nodes.
Optimising storage for this great mass of pre-processed text is also a
secondary requirement. Finally, the recruited engineer is expected to study
and propose the development and/or adaptation of a friendly corpus query
platform for the project researchers. This interface will facilitate
extracting usages for given lexical units, both for manual inspection and
for automatic clustering algorithms.

In addition to these tasks, it will be possible to carry out more
exploratory research in the project, according to the interests of the
recruited person.

### Environment

This position is funded by the ANR SELEXINI project
. The recruited person will participate in
project meetings, co-author articles, and interact with other SELEXINI
members in French research institutions. The engineer will be
supervised by Carlos
Ramisch <http://pageperso.lis-lab.fr/~carlos.ramisch/> in coordination with
SELEXINI partners. The recruited person will become a member of the TALEP
team , specialised in computational linguistics.
TALEP is a dynamic and international team of LIS ,
a computer science lab located on the Luminy campus
<https://sciences.univ-amu.fr/sites-geographiques/site-luminy> in
Marseille. Aix Marseille University is one of
the largest universities in France, providing a lively and diverse research
environment. Depending on the covid-19 situation at the time, partly remote
work can be negotiated.
