Using LLMs for the specification of data sharing policies - CDD - Paris-Saclay F/H

Job description: “Join the CEA to give meaning to your activity, lead and support national and international R&D projects, cultivate and bring to life your spirit of curiosity.” IN SUMMARY, WHAT DO WE OFFER YOU? The CEA is looking for an Engineer in use of LLMs for the specification of data sharing policies for the CEA/DRT (Technological Research Directorate). This 36-month fixed-term management position is based at the Nano-Innov site in Paris-Saclay, Essonne (91). This is a position to be filled as soon as possible. WHY JOIN US? The development of physical or digital systems is complex and involves technical and human challenges. The first step is to formalize ideas by writing specifications or specifications, generally written in natural language by functional analysts. These documents are crucial for the project and facilitate communication between stakeholders. Requirements engineering proposes techniques (reviews, modeling, formalization) to improve the quality of documents (consistency, completeness) and correct defects before the implementation of the system. Large model neural networks (LLM) bring new possibilities in this field [2]. We propose to use a conversational agent (ChatGPT, Lama) to model data sharing policies (ODRL[1]) from natural text. The tool will recommend rewriting options inspired by INCOSE and EARS standards, analyze the results and provide an audit on the quality of the obtained model. LLMs are particularly promising for: transforming unstructured requirements into structured models such as EARS or user stories [2] classifying requirements [3]: behavioral, non-functional, etc. as defined for example in [4] report ambiguities, inconsistencies or potential violations based on predefined validation heuristics [5] [2] However, LLMs have limitations: hallucinations, algorithmic biases and limited generalization [2]. To overcome this, we suggest hybridizing, as in [1], LLMs with other techniques (NLP, process algebras) in order to reduce these impacts. WHAT DO WE EXPECT FROM YOU? Within the "Intelligent Requirements" team of the laboratory, your challenge will consist in: Determining schemas or a controlled language to represent the ODRL model Determining the effectiveness of different techniques and formalisms, such as NLP [6] or inspiration from the Bleu metric [7], to avoid hallucinations during rewriting Analyze, manage or generate training data for LLMs Configure and manage one or more LLMs with the most effective techniques to improve the consistency and completeness of data sharing policies Develop the software tools necessary for the above work.

Institute description: The LECS laboratory (Laboratoire d'Études et de Conception de Systèmes) of the DILS department within the LIST institute of the DRT directorate of the CEA focuses mainly on cybersecurity and data protection in distributed systems. It participates in projects such as the TASTING project, which aims to modernize and secure energy infrastructures. LECS collaborates with several research organizations and industrial partners such as RTE to develop solutions based on formal methods of real-time verification.
