Data Annotation in Bath
Labelling data for Bath organisations training or evaluating machine learning models. Consistency matters more than volume here — annotators who disagree with each other teach a model to be uncertain in exactly the places where your business needed it to be decisive.
Why this comes up
The problem
A model needs training data and labelling has started without written guidelines. Different people are making different judgements on the same kind of example.
What you get
What we deliver
- Written guidelines covering the edge cases, since those cause the disagreement
- A pilot round measuring agreement between annotators before scaling up
- Labelling carried out against those guidelines, with questions fed back
- Inter-annotator agreement measured, so consistency is a number not a hope
- A held-out evaluation set labelled to a higher standard than training data
- A route to relabel as guidelines evolve, because they will

Data Annotation in Bath — common questions
- Why measure agreement between annotators?
- Because it caps how good the model can be. If two trained people disagree on a quarter of examples, the labels encode that inconsistency and the model learns it. Low agreement almost always means the guidelines are ambiguous rather than the annotators careless.
- How much labelled data do we need?
- Less than most expect if it is consistent — often hundreds to a few thousand examples for a focused task. A smaller, carefully labelled set reliably beats a larger inconsistent one, which is the opposite of how the question is usually framed.
- Can AI do the labelling?
- It can pre-label, with people reviewing and correcting, which speeds the work considerably. Fully automated labelling teaches your model to imitate another model's mistakes, so at minimum the evaluation set should be human-labelled.
- What about sensitive data?
- Annotation means people reading your data, so access controls, agreements and — where possible — anonymisation matter. For health or financial records this needs settling before any labelling begins, not as a later review.
- Do you work with businesses across Somerset?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South West, including Bath and the surrounding Somerset area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Bath businesses do you usually work with?
- Visitor booking and ticketing for heritage operators, and brand work for independents competing on a very crowded high street. Beyond that we work across Tourism & Heritage, Higher Education, Professional Services, Retail and Software.
- Do you cover the areas around Bath?
- Yes — we work throughout South West, including Bristol, Salisbury, Gloucester. Bath is an urban area of roughly 95,000+, and we take on work across the wider Somerset region rather than the city boundary alone.
