Abstract

fetched live from OpenAlex

"Model Driven Software Development" is a recent trend in development of software-intensive systems. In the Model Driven Software Development process, all knowledge pertaining to the software system to be built is represented in the form of models, in the right formalism(s) and at the right level of abstraction. At the highest level of abstraction, domain models, rather than generic models are used. Although the idea of developing the software system at a higher abstraction level is appealing, many fundamental questions remain unresolved. Many issues such as how to define the syntax and semantics of models, how to represent and store models and how to trace model evolution should be addressed properly. In this thesis, the focus is on model transformations and the open problems related to it. In particular, how to compare models, how to trace model evolution (with as a goal to undo and redo model changes), how to deal with meta-model evolution, and ultimately with semantics evolution are explored. For each issue, we analyze problems, and propose some solutions. We use small case studies to make issues more concrete. All case studies are developed in AToM3 (A Tool for Multi-formalism and Meta-Modeling), developed in the Modeling, Simulation and Design Lab (MSDL) in the School of Computer Science of McGill University.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
