The Littoral Environment and Society laboratory (Mixed Research Unit n ° 7266) proposes a position of Engineer of Study in computer science. The engineer will have to implement and test various methods of consistency checks on a historical database of eighteenth-century maritime commerce, in the context of the PORTIC project, funded by the French National Agency for Research (ANR). It is a question of crossing two corpus of imperfect historical data concerning the eighteenth century maritime trade and the balance of trade. Digital humanities accompany all stages of the project. The numerical approaches that will be used are aimed at tagging the corpus in order to distinguish different levels of quality within the data. The mission begins on April 1st, 2019 and will be realized also in interaction with the L3I computer science laboratory, at La Rochelle.


The engineer will perform his mission in a creative and autonomous way in a highly interdisciplinary environment, with open-source tools. It involves developing data qualification services over an open database.
- Participate in the development of consultation, control and management tools (scripts, procedures, requests, reporting)
- Assist the project management in the drafting of specifications
- Write the functional and technical documentation
The engineer will use data mining methods to identify aberrations or inconsistency in the corpus. This involves reusing open-source libraries: unsupervised classification methods for pattern and similarity detection, non-parametric statistics for the detection of exceptional values. Specifically, by designing and programming an application to activate these methods and exploit their outputs to tag the data, the contribution of the engineer will help to determine finely the various levels of data quality inside the corpus.
Finally, depending on the results obtained, the work may be the subject of scientific publications and the engineer will be closely associated with this task, as co-author or principal author, where appropriate. This post therefore offers the opportunity to learn to write a scientific paper, on different media (article, poster) and will enhance the work done for the future since the code will be released under free license.


Candidate should have a master or an engineer diploma in computer sciences.
- The position therefore requires programming skills (REST Service, Java, Python) as well as database (Postgres, RDF, graphs, UML).
- Skills would be appreciated in mathematics/statistics and one or more of these technologies: Strasbon, Postgis, Neo4J, R.
- The position requires a continuous dialogue with the various actors of the project and their various disciplines (history, economics, geomatics, computer science).

Work Context

The engineer will be recruited by the CNRS, at the Rochelle, in the the Mixed Research Unit Littoral Environment and Societies, (U.M.R. 7266 LIENSs). This laboratory brings together scientific experts from the disciplines of ecology, geography, biology, history, molecular chemistry and earth sciences and questions issues related to sustainable development and climate change around coastal areas (https : //lienss.univ-larochelle.fr/). The engineer will thus integrate a highly interdisciplinary environment and in particular the DISA service, a database platform under Christine Plumejeaud responsability. DISA is at the crossroads of numerous scientific projects in order to offer a better capacity for cross-referencing highly heterogeneous data and to promote the implementation of FAIR principles in research.
The PORTIC team in La Rochelle is coordinated by Christine Plumejeaud-Perreau, computer scientist responsible for the DISA platform at LIENSs. She has been working for 5 years with Alain Bouju, Associate Professor with Habilitation to lead Research in Computer Science at the Laboratory of Computer Science, Images and Interactions (L3i) at the University of La Rochelle since 2014. The engineer will therefore be in strong interaction with these two people to carry out his mission.
The study engineer will will access all the facilities offered by the Very Large Research Infrastructure HumaNum (virtual machine for deployment in production tools developed, GIT, storage space). All its work will be released by PORTIC under free license. This fixed-term contract is envisaged as a prelude to a PhD, which is also online.

Additional Information

The application must include a CV, a letter of motivation, a transcript of Master 2 or engineering school last year, as well as the latest internship report.
