Seven ways we support AI teams
Managed data programmes delivered by calibrated African analysts, governed by research methodology and measurable quality controls.
Managed Annotation & Data Curation
End-to-end annotation programmes run by trained, calibrated analysts against your schema or ours, with multi-pass review and adjudication built into the workflow.
- Client-defined schemas, taxonomies and labelling guidelines
- Multi-pass annotation with adjudication of disagreements
- MIF™ available as an option for meaning-rich African-context tasks
African Data Collection & Corpus Development
Purpose-built collection of African text, speech and conversational data, sourced with consent and documented provenance.
- Nigerian English, Nigerian Pidgin, Standard English and Nigerian code-mixed speech; other African languages expanding / scoped on request
- Task-targeted prompts, dialogue, transcription and metadata capture
- Documented sourcing, consent and provenance records
Human Model Evaluation & Red-Team Review
Calibrated human raters assess model outputs for meaning, cultural appropriateness, safety and failure modes in African contexts.
- Side-by-side preference, rubric scoring and free-form critique
- Adversarial and red-team probing for context-specific failure modes
- Rater calibration and agreement tracking across every panel
Benchmarking & Diagnostic Evaluation
Contamination-aware benchmark runs with per-dimension diagnostics, so you learn where a model breaks rather than a single headline number.
- MIS™ scoring on the Nigerian register/discourse benchmark
- Per-dimension error analysis and failure taxonomies
- Contamination-aware holdout design and rotation
Dataset QA, Adjudication & Gold-Set Creation
Independent audit of existing datasets, disagreement resolution and construction of defensible gold sets for training and evaluation.
- Label audit, error rate estimation and inter-annotator agreement
- Senior-reviewer adjudication of contested items
- Gold-set construction with documented decision rationale
Managed AI Talent Deployment
Standing panels of vetted African analysts assigned to your programme, managed by Cihan with quality reporting and continuity of expertise.
- Dedicated, NDA-bound panels with domain and language fit
- Cihan-managed onboarding, calibration and quality oversight
- Capacity that scales with your evaluation cadence
CMIA Certification & Workforce Development
Training and CMIA certification delivered through Cihan Digital Academy — build the capability inside your own team or ours.
- Certified Meaning Interpretation Analyst curriculum
- Cohort, in-house and enterprise delivery
- Verifiable credentials on completion
MIF™ is a proprietary framework we offer where meaning-rich African-context tasks call for it. It is optional — we also work to your own schemas, rubrics and evaluation task types.
