          2. Research project or operation

          The German-French project TETRA focuses on the development of an AI based toolbox and methodology for the water domain. This project will begin in June 2023 until June 2026 (3 years). Four partners are involved, two German et two French partners, two private compagnies (SEBA, Thalès) and two public research centers (Fraunhofer IOSB, ICube). The project is organized into several work packages. This postdoctoral position is concerned by one of the work packages (WP6): its aim is to develop a decision support system exploiting feedbacks from hydro-ecosystem restoration operations.

          The restoration or renaturation of hydro-ecosystems is a major challenge for the coming years in order to protect and preserve the quality and quantity of river water. In addition, dam or power plant managers are obliged by European and national rules to renaturalize parts of their operating area. Unfortunately, restoration experiences are few and far between. A synthesis of feedbacks has been undertaken for restoration operations along the Rhine (https: // obs-rhin.engees.eu/). Operation reports and interview sheets have also been collected but not used. However, this information, including feedback on errors or unexpected results, would be essential to guide or help implement new projects.

          3.Activities

          · Description of the research activities:

          To exploit this information, we propose to develop AI methods relying on case- based reasoning (CBR). CBR consists of solving new problems by reusing the solution of similar problems that have already been solved. A case corresponds to a problem-solving episode usually represented by a problem-solution pair. Cases are recorded in a case base. A source case is an element of the case base. The CBR process consists of solving a new problem, the target problem, using the case base. A common way of doing this is to select a source case similar to the target problem (case retrieval step) and to modify the retrieved case so that it provides a solution that hypothetically solves the target problem (case adaptation step). After these inference steps, some learning steps are sometimes implemented. CBR has been used on many applications e.g., agriculture or cooking. The following steps are to be developed:

          Step 1: Structuration of a case base: information extracted from existing websites and texts will be formalized within cases (a renaturation operation, context, documents and results, etc.). Text mining will be performed by partner Thalès to extract information from textual documents. A graph representation will be researched to represent the information for each operation (knowledge graphs / conceptual graphs). Different levels of representation will be studied and organized in a hierarchical way, with regards to domain knowledge. Expert rules can also be used to complete the cases. Cases will be provided to to populate the ontology developed in another work package (WP4).

          Step 2: Problem description and definition of the case retrieval step: this step will rely on graph matching, including approximative graph matching based on ontological reasoning, in relation with WP4. Various similarity measures and graph mining approaches will also be experimented.

          Step 3: Solution adaptation: an adaptation approach based on the semantical and numerical information describing both source and target cases will be studied. Besides, A query interface will be developed with the help of an engineer (6 moths) or the decision support system: the user describes a site or an operation and the system retrieves and displays similar sites/operations with their results., and suggests adaptions.
