Computer science dissertation topics and research questions

A build alone is not a dissertation. Each idea below pairs an artefact with an evaluation question you can defend in a viva.

Topic angles with worked research questions

Retrieval-augmented generation accuracy

How does chunking strategy affect factual accuracy in a retrieval-augmented question-answering system over a fixed corpus?

Measurable, reproducible, and the artefact doubles as your experimental apparatus.

Static analysis and developer trust

How do developers triage warnings produced by static analysis tools, and which factors predict dismissal?

Mixed methods: tool output plus short think-aloud sessions.

Stress-test this question

Accessibility regressions

What proportion of automated accessibility violations persist across releases of popular open-source web apps?

Fully public data, scriptable collection, clear quantitative results.

Coach modes for computer science

Each mode questions and explains — it never writes your dissertation for you.

Your starter workflow

  1. 1Guided setupFifteen minutes from blank page to Big Idea, research question and three sources.
  2. 2The Big Idea canvasTurn a vague interest into a defensible, narrow topic.
  3. 3Research question coachStress-test scope, feasibility and answerability before you commit.
  4. 4Literature matrixRecord sources, spot the gap and build your argument from the evidence.
  5. 5Methodology labChoose and defend a design that actually answers your question.

Computer science dissertation questions students ask

Does my project need an evaluation?
Yes. Marks come from the evaluation and the argument, not the number of features you shipped.
Can I use an existing dataset?
Absolutely — a well-justified public dataset is often stronger than a small one you collect yourself.

Find a subject angle that is narrow enough to research and interesting enough to finish.

How to choose a dissertation topic

A practical method for choosing a dissertation topic you can actually research: start from curiosity, test feasibility, and narrow until the topic is doable.

What is a research gap?

Research gaps explained in plain English: the main types of gap, how to find one in your reading, and how to write a gap statement you can defend.
