Contexte :
The restoration or naturalization of hydro-ecosystems is a major challenge for the coming years in order to protect and preserve the quality and quantity of river water. Many restoration works – both recent and historical – have generated large amounts of textual documentation (reports, archival documents, project plans, regulations, scientific articles) and visual material (maps, drawings, aerial/satellite imagery, photographs, cross-sectional charts). However, that material is often unstructured, scattered across institutions, in multiple languages, and not organized to support comparative analysis, learning, or decision-making effectively.

Sujet :
The main research task involves applying and refining VLMs to extract complementary information from visual and textual data. The VLMs should recognize and describe restoration structures, spatial configurations, and temporal stages (before, during, and after restoration) from images. They should extract objectives, methodologies, outcomes, and environmental parameters from text. A key scientific challenge lies in the multi-modal alignment of information linking visual elements and textual references to produce consistent and interpretable outcomes.

Building on these results, the internship will contribute to the enrichment of an already existing structured knowledge model (ontology), describing restoration cases through key properties including intervention type, environmental context, methods, results, constraints, and costs. In addition to enriching the knowledge model, another key point is populating the knowledge model by constructing knowledge graphs with information extracted from images and text, ensuring querying, comparison, and visualization by researchers and practitioners.

Profil du candidat :
Knowledge on data science methods, knowledge representation and reasoning, knowledge graphs.
Languages: Python, java, owl/sparql.
Interest in the application domain, ability to work with experts who are not computer scientists would be appreciated.

Formation et compétences requises :
Student about to graduate a Master or Engineer (Bac + 5) with a specialization in Computer Science.
