WORKFLOW
Our Annotation Pipeline for This Industry
A structured, domain-specific workflow — from data ingestion to delivery — designed for your industry's unique requirements.
2
Shelf Image Annotation
Bounding boxes and segmentation masks for individual products on shelves; planogram position mapping (shelf, bay, facing); out-of-stock and misplacement detection labels.
3
Product Attribute Labeling
Per-product attributes: brand, flavor, size, price tag value, promotional status, damage/expiry flags. Multi-label classification for recommendation training data.
4
Sentiment & Review Annotation
Customer reviews annotated for sentiment (5-class), aspect categories (quality, price, delivery, fit), and entity extraction (product names, features, complaints).
5
Cross-Reference QA
Annotations validated against client's planogram database; SKU identification accuracy verified via barcode-to-annotation matching on gold-set samples.
6
Analytics-Ready Delivery
Labeled data delivered in COCO, Pascal VOC, or custom retail analytics format with per-store, per-category aggregation metadata for downstream compliance scoring models.

EXPERTISE
Why Domain Expertise Matters
Generic annotation vendors can label data. Domain experts label it correctly. Here's why the difference matters in your industry.
SKU Similarity Demands Product Knowledge
Distinguishing between 'Diet Coke 12oz' and 'Coke Zero 12oz' from a shelf photo requires annotators trained on your specific catalog. Our SKU training program uses 10+ reference images per product to achieve 96.8% identification accuracy across 10K+ SKUs.
Planogram Context Changes Everything
A product in the wrong position isn't just a labeling error — it's a compliance signal. Our annotators understand planogram logic: facing counts, shelf positioning, promotional placement rules — delivering data that powers compliance scoring, not just object detection.
Multilingual Sentiment Requires Cultural Nuance
Sarcasm, regional slang, and cultural expectations vary across markets. Our multilingual annotation teams handle sentiment analysis across 25+ languages with aspect-level granularity — catching nuances that automated sentiment tools miss.
