Master Thesis: Evaluating AI Code Knowledge Bases for Developer Productivity
Join our Team
About this opportunity:
AI coding assistants become far more useful when they are given structured knowledge about a large codebase — its architecture, interfaces, and design intent. Such AI code knowledge bases are increasingly being adopted, but their real benefit is often assumed rather than measured.
This thesis asks the harder question: does an AI code knowledge base actually make developers faster, their answers more correct, and their onboarding shorter — and by how much? The student will design and run a rigorous evaluation of AI code knowledge bases on real software engineering tasks, turning assumed productivity gains into evidence.
What you will do:
-
Study how AI code knowledge bases are used by coding assistants today and where existing evaluations stop short of measuring real developer productivity.
-
Design an evaluation methodology: task selection from real work (bug fixes, feature changes, code comprehension), ground-truth definition, and metrics for correctness, time-to-answer, context/token cost, and trust.
-
Design telemetry into the knowledge base itself: whether it is consulted at all, which entries are retrieved, and whether a retrieved answer is used or discarded by the human or agent working on the task at hand.
-
Run controlled studies — knowledge-base-assisted vs. baseline assistant, and where feasible with developers — capturing both objective outcomes and perceived usefulness.
-
Analyse where the knowledge base helps most and least, and why, feeding concrete improvement recommendations back into how knowledge bases are generated.
-
Deliver a reusable evaluation framework and a written study with statistically honest conclusions about impact.
The skills you bring:
-
Currently pursuing a Master's Degree in Computer Science, Software Engineering, Data Science, or a similar field.
-
Solid Python; comfort with LLM/agent tooling and with reading real source code and commit history.
-
Interest in empirical software engineering, experiment design, and evaluation of AI systems.
-
Statistical literacy: designing fair comparisons, and report results with their uncertainty and limitations.
-
Familiarity with retrieval-augmented generation (RAG) and AI coding assistants is a plus.
-
Experience with cloud AI/ML services (AWS or similar) is a plus.
