Psychiatric data labelling by expert psychiatrists.

We provide psychiatric and mental health data labelling and AI evaluation, combining psychiatrists from our clinical network with PhD data scientists.

Mental health data is nuanced, sensitive and often ambiguous. The people labelling it should understand it.

MENTAL HEALTH CHATBOT · CLINICAL REVIEWILLUSTRATIVE EXAMPLE
USER"I don't really see the point in anything any more."
AI RESPONSE It sounds like you're having a tough time. Try going for a walk or doing something you enjoy.
Tone: supportive.
Risk: not explored, potential safety concern. The response does not ask about thoughts of self-harm or suicide.
Signposting: missing. No crisis or support information is offered.
Psychiatrists assess each response against agreed criteria, including how risk is handled.
WHAT WE COVER

Mental health data, reviewed with care.

Clinical notes and letters
Labelling symptoms, diagnoses, risk factors and outcomes in psychiatric notes, letters and reports.
Conversations and transcripts
Annotating consultation, therapy or chatbot transcripts for symptoms, risk indicators and quality of response.
Risk and severity grading
Grading risk indicators and symptom severity against criteria agreed with you before work begins.
Diagnostic classification
Assigning cases to diagnostic categories using the classification your project needs, such as ICD-11 or DSM-5-TR.
Mental health AI evaluation
Reviewing chatbot and LLM responses for safety, appropriateness, risk handling and signposting.
Review of existing labels
Checking labels you already have for clinical accuracy, consistency and suitability.
WHY IT IS DIFFERENT

Psychiatric data needs psychiatric judgement.

01

Ambiguity is built in

Symptoms overlap, and the same words can mean different things in different contexts. Agreement between reviewers is often lower than in other specialties, so independent review and adjudication matter more.

02

Risk needs a plan

Mental health data can include self-harm and suicide. We agree with you how risk is defined, graded and flagged before any review starts.

03

The data is sensitive

Data access, handling and confidentiality are agreed during scoping. Reviewers sign confidentiality and data protection agreements before they see any project data.

HOW WE WORK

Clinical judgement, measured properly.

We agree the labelling criteria, risk definitions and review design with you during scoping. Where appropriate, each item is reviewed independently by more than one psychiatrist, and disagreements are resolved by a senior reviewer.

PhD data scientists measure how often reviewers agree, so you know how reliable the labels are and where the task is genuinely hard. Read our guide to ground truth and reviewer agreement.

WHAT YOU RECEIVE · DEPENDING ON SCOPE

  • Labelled datasets
  • Clinically reviewed labels
  • Risk and severity grading
  • Expert-reviewed AI responses
  • Reviewer agreement analysis where appropriate
  • Documented labelling criteria
  • Structured report with recommendations

Our evaluations provide clinical insight to support product development. They do not certify clinical safety, confer regulatory approval or replace formal validation requirements.
