Case study

Nine hundred and sixty-seven hours of annotation across three task types in six weeks.

An AI company needed 967 hours of annotation across three different task types in six weeks, where each task carries its own labeling rules and failure modes.

Why this mattered

Outcome before process.

Multi-type annotation is three jobs in one: each task has its own guidelines, edge cases, and consistency traps, and mixing them without per-task control degrades the dataset.

The problem to solve

Why the work was difficult, and what MoniSa changed in-flight.

Annotation across three task types fails when one set of guidelines is stretched across all of them, or when consistency is not tracked per task.

The challenge

The problem to solve

Annotation across three task types fails when one set of guidelines is stretched across all of them, or when consistency is not tracked per task.

The company needed object detection, sentiment, and NER each held to their own standard within one fast-moving engagement.

Operating response

What MoniSa changed

MoniSa ran each task type with its own guidelines and reviewers, tracking consistency per task across the six-week window.

  • Per-task guidelinesObject detection, sentiment, and NER each had their own annotation rules and acceptance examples.
  • Task-specific reviewReviewers tracked consistency within each task type, not a blended average.
  • Window disciplineWork moved on a schedule that held quality across the six-week deadline.

Results

Measured outcomes from this engagement.

The company received 967 hours of annotation across object detection, sentiment, and named-entity recognition at reviewed quality, each task held to its own standard within six weeks.

Selection logic

What protected the result.

Multi-type annotation needs per-task guidelines and review, not one blended standard stretched across three jobs.

Why the fit was real

Why the fit was real

Multi-type annotation needs per-task guidelines and review, not one blended standard stretched across three jobs.

What decided the result

What decided the result

Holding each task type to its own standard mattered more than a single headline accuracy number.

What buyers can reuse

What buyers can reuse

  • Multi-type annotation is three jobs: each task needs its own guidelines and consistency tracking.
  • A blended quality average hides weak task types; per-task review is what keeps the dataset usable.
  • The evidence keeps the client details confidential and attributes the metrics only to this engagement.

AI data servicesLarge-language-model data coverage without client-name exposure.

LLM training data coverage

The challenge. A model team needed multilingual training data across rare and indigenous language tracks.

What we did. MoniSa built language-specific sourcing, annotation, and review paths for the program.

The result. The buyer received structured transcript output for model training across a broad multilingual scope.

AI data servicesMixed-script Document AI dataset moved through validation.

Document AI OCR annotation

Problem. A Document AI buyer needed readable, consistently labeled files across scripts and document types.

Action. MoniSa grouped files by script, validated structural labels, and escalated disagreements.

Result. The buyer received an annotated dataset prepared for Document AI model training.

AI output reviewSafety annotation stabilized across multilingual batches.

Multilingual content safety

Problem. A content-safety team needed consistent risk labeling across languages and cultures.

Action. MoniSa tightened examples, retrained reviewers, and tracked recurring error patterns.

Result. The buyer received a steadier multilingual safety-review workflow with fewer correction cycles.
