Engineer / PostDoc position

Information extraction, Text Recognition in Historical Document Collections


LITIS (Laboratoire d’Informatique, Traitement de l’information et des Systèmes) is a research laboratory
associated to the University of Rouen Normandie, Le Havre Normandie Normandie, and School of
Engineering INSA Rouen Normandie. Research at LITIS is organized around 7 research teams which
contribute to 3 main application domains: Access to Information, Biomedical Information Processing,
Ambient Intelligence. LITIS currently includes 90 faculty staff members, 50 PhD students, 10 PostDoc
and Research Engineers. The Machine Learning team of LITIS is developing research in modeling
unstructured data (signals, images, text, etc…) with machine learning algorithms and statistical models.
For more than two decades it contributes to the development of reading systems and document image
analysis for various applications such as postal automation, business document exchange, digital
libraries, etc.


EURHISFIRM aims at developing a research infrastructure to connect, collect, collate, align, and share
reliable long-run company-level data for Europe to enable researchers, policymakers and other
stakeholders to analyze, develop, and evaluate effective strategies to promote investment and
economic growth. To achieve this goal, EURHISFIRM develops innovative tools to spark a “Big data”
revolution in the historical social sciences and to open access to cultural heritage
EURHISFIRM is a project funded by the European Commission within the Infrastructure Development
Program of Horizon 2020. The goal of the Program is to develop world-class research infrastructures
lasting for decades ( ). Research
infrastructures are facilities, resources and services used by the science community to foster innovation
and extend the frontiers of knowledge.
The first phase of the Infrastructure Development Program lasts for three years. It aims at developing
an in-depth design study of the Research Infrastructure. After this phase, Development and
Consolidation Phases follow if further applications will be successful. EURHISFIRM brings together eleven
research institutions in economics, history, information technologies and data science from seven
European countries.

Within the project, you will be in charge of developing text information recognition technologies (ICR)
from historical document images (mostly printed), and information extraction from these data (such as
person names, names of companies, dates, positions, stock prices etc…). The datasets are made of
financial yearbooks and price lists of European companies, in different European languages. Your mission
includes :
1- the development of a machine learning based reading system of text lines composed of both
deep optical models, and language models (statistical, and grammar based). Layout analysis falls
out of the scope of the mission.
2- Data preparation for evaluation purposes
3- Benchmarking with other technologies (commercial products)
4- Integration of the system as a web service allowing its integration and deployment into a full
5- Coordination with partners of the project regarding datasets preparation and collation of
datasets, as well as software interoperability with other developments within the EurHisFirm

Requirements :

The successful applicant should have a strong record in statistical machine learning and have experience
in one popular platform and programming language in the field, so as to design, develop and make the
prototype evolve.
• PhD, or Computer Engineer, with a good record in Machine Learning
• demonstrates ability to work in a team, curious and rigorous spirit
• Excellent written and verbal communication skills (French and English)

Technical skills :

C/C++, Python, Tensor Flow, Keras, and other librairies (Numpy, OpenCV, Kaldi ..), knowledge about
web technologies
