PhD position in “Citation extraction classification for knowledge extraction and analysis of a scientific field”

Starting date: October 01, 2021

Deadline for Applications: July 5th, 2021

Keywords: natural language processing, citation classification, transfer learning, deep learning

Context

The NanoBubbles ERC project objective is to understand how, when and why science fails to correct itself. The project’s focus is nanobiology and it combines approaches from the natural, computer science, and social sciences and the humanities (Science and Technology Studies) to understand how error correction in science works and what obstacles it faces. For this purpose, we aim to trace claims and corrections in various channels of scientific communication (journals, social media, advertisements, conference programs, etc.) via natural language processing.

The challenge is to build data sets, models and tools that enable organising and analysing the rapidly evolving ecology of online comments complementary to conventional scientific records:

  • This means not only counting references to a document but  also assessing and leveraging the content of both cited and  citing document.
  • This means not only identifying named entity, claims and  counter claims but also extracting structured knowledge  from text.
  • This means not only taking advantage of existing data to  learn models but also building tools for creation and  annotation of new sets of data so to train advance language  models.

Project objectives

Citations are an important indicator of the state of a scientific field. They reflect how authors frame their work and influence its adoption by future researchers. However, despite recent work in NLP [Bakhti2018, Jurgens2016, Pride2019, Yu2020], citation behaviour and how it can be used to point out error correction lack large scale and deep citation analyses.

The objective of this PhD is to design new NLP method to detect and qualify citations and extract citation network in scientific research.

Skills

  • Master 2 in Natural Language Processing, computer science or data  science.
  • Programming experience in Python and in a deep learning framework.
  • Previous experience in NER, RE and dataset manipulation would be a  plus.

Scientific environment

The thesis will be conducted within the Sigma and Getalp teams of the LIG laboratory (http://sigma.imag.fr and https://lig-getalp.imag.fr). The recruited person will be welcomed within the teams which offer a stimulating, multinational and pleasant working environment. The means to carry out the PhD will be provided both in terms of missions in France and abroad and in terms of equipment (personal computer, access to the LIG GPU servers).  The person will also be required to collaborate with several teams involved in the ERC Nanobubbles project, in particular with researchers from the IRIT lab (Toulouse, France), University of Paris Sorbonne as well as researchers from Maastricht University, Radboud Universiteit and University of Twente based in the Netherlands.

Instructions for applying

Applications are expected until July 5th, 2021. They must contain: CV + letter/message of motivation + master notes + letter(s) of recommendation, and be addressed to Cyril Labbé (cyril.labbe@imag.fr), François Portet (francois.portet@imag.fr) and Yasemin J. Erden (y.j.erden@utwente.nl).

Applications will be considered on the fly. It is therefore advisable to apply as soon as possible.
