An AI company needed 967 hours of annotation spanning object detection, sentiment analysis, and named-entity recognition, delivered within a six-week window.
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
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.
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 guidelines
Object detection, sentiment, and NER each had their own annotation rules and acceptance examples.
Task-specific review
Reviewers tracked consistency within each task type, not a blended average.
Window discipline
Work 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 under project-scoped review, each task held to its own standard within six weeks.

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

Operating response
The change that was actually made.
Not the result — the decision taken mid-programme that the result depended on.
Three task types, three rulebooks
Object detection, sentiment and NER each had their own rules, examples and reviewers. Consistency was tracked per task, because a single accuracy number across three tasks hides which one is drifting.

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.

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.

What happens if you cannot staff one of my language pairs?
For the proposed project, ask for pair-by-pair availability or a recruitment window in writing before agreeing a date. Define qualification and pilot approval for any new contributor before live work. A coverage claim should be checkable before the scope is signed.
