From Student Risk Prediction to SC2R: Semantics-Constrained Counterfactual Recourse for Educational Decision Support
Ngoc Luyen Le, Marie-Hélène Abel, Bertrand Laforge
Learning analytics models can identify students at risk of poor performance, but they do not directly indicate which interventions are feasible, actionable, and compatible with edu…
From Prompts to Context: An Ontology-Driven Framework for Human-Generative AI Collaboration
Ngoc Luyen Le, Marie-Hélène Abel, Bertrand Laforge
Collaborations with Generative AI often begin with a short prompt and end with an opaque output, leaving implicit who was involved, what task was being pursued, which resources wer…
From Learning Resources to Competencies: LLM-Based Tagging with Evidence and Graph Constraints
Ngoc Luyen Le, Marie-Hélène Abel, Bertrand Laforge
Linking learning resources to a structured competency framework is key to enabling competency-based search and curriculum analytics in Learning Management Systems (LMS). However, m…
When Can We Trust Early Warnings? Leakage-Excluded Early Outcome Prediction from LMS Interaction Logs
Ngoc Luyen Le, Marie-Hélène Abel, Bertrand Laforge
Early-warning models built from Learning Management System (LMS) logs aim to predict end-of-course outcomes early enough to enable timely learner support. However, reported "early"…
KG-First, LLM-Fallback: A Hybrid Microservice for Grounded Skill Search and Explanation
Ngoc Luyen Le, Marie-Hélène Abel, Bertrand Laforge
Authoritative competency frameworks such as ESCO, ROME, and O*NET are essential for aligning education with labor market needs, yet their technical complexity and structural hetero…
Position resolution and particle identification with the ATLAS EM calorimeter
Roberto Sacco
In the years between 2000 and 2002 several pre-series and series modules of the ATLAS EM barrel and end-cap calorimeter were exposed to electron, photon and pion beams. The perform…
Hadron Energy Reconstruction for the ATLAS Calorimetry in the Framework of the Non-parametrical Method
ATLAS Collaboration
This paper discusses hadron energy reconstruction for the ATLAS barrel prototype combined calorimeter (consisting of a lead-liquid argon electromagnetic part and an iron-scintillat…
