Abstract

The task of generating reports in Model-Based Systems Engineering (MBSE) often demands significant effort and technical expertise, creating barriers resulting in inflexibility. This thesis addresses data scarcity through domain adaptation, controlled natural language (CNL), and retrieval-augmented generation (RAG). The experimental results demonstrate promising potential for interactive model reporting, evaluated through the proof-of-concept implementation Mo-Lab.

Keywords: Model-Based Systems Engineering, openCAESAR, text-to-SPARQL, domain adaptation, data scarcity

Building

Requirements: LuaLaTeX, Biber, makeglossaries.

./compile.sh

The build includes cover-sheet.pdf and optionally extended-abstract.pdf if present (add manually if you have it).
