Data for Retail & E-commerce AI
Catalog enrichment, search relevance, and visual-search datasets that lift conversion.
Retail AI compounds: better attributes drive better search, better search drives better recommendations. We build the catalog, query, and visual datasets behind that flywheel.
Challenges we solve
- Sparse and inconsistent product attributes
- Long-tail query understanding across languages
- Visual similarity at SKU scale
- Review and Q&A normalization
How we help retail teams
Catalog enrichment at SKU scale
Attribute extraction, taxonomy mapping, and image tagging across millions of SKUs with QA gates.
Query–item relevance
Human-graded query/item pairs powering learning-to-rank and semantic search models.
Visual search ground truth
Same-item, similar-item, and complementary-item triplets curated by trained labelers.
How we deliver
- 01
Scoping & guideline co-design
We meet with your ML and product leads to map model objectives, target metrics, and the failure modes the next training run must address. Together we draft an annotation rubric and a calibration set.
- 02
Pilot & calibration
A small batch goes through our reviewers and yours in parallel. We measure agreement, surface ambiguous cases, and lock the guidelines before we scale.
- 03
Production labeling
Domain-expert annotators with model-assisted tooling work through the queue. Per-batch quality dashboards stream to your team.
- 04
Multi-pass QA & adjudication
Independent reviewers re-label a statistical sample and adjudicate disagreements. Golden-set F1 and per-class accuracy are reported every batch.
- 05
Delivery, evaluation & iteration
Data ships in your preferred schema. We run evaluation against your held-out set, capture model-lift signals, and roll learnings into the next sprint of guidelines.
What you get
Production-ready labeled dataset
Delivered in the schema and storage of your choice (S3, GCS, Azure, on-prem) with versioned manifests.
Annotation guidelines & calibration set
A living document plus a held-out calibration set you can re-use to onboard future vendors or in-house teams.
Per-batch quality reports
Inter-annotator agreement, golden-set F1, per-class accuracy, throughput, and reviewer-level performance.
Audit trail
Per-label reviewer, timestamp, and version history — ready for regulator and customer audits.
Handover & training
Documentation, tooling access, and a working session so your team can extend the pipeline internally.
Data we deliver
Use cases
Built for production AI, not pilots
GDPR & CCPA compliant
Lawful basis, data-subject rights workflows and documented retention policies on every engagement.
Senior delivery ownership
A named senior program lead owns every engagement End-to-End — no ticket queues, no vendor relay.
Human-in-the-loop QA
Multi-pass review, gold-set calibration and consensus scoring — quality reviewed by people, not just scripts.
NDA & secure handling
NDAs by default, role-based access, EU/US data-residency options and full chain-of-custody on project assets.
Why teams choose DOT Data Labs
Domain-expert workforce
Vetted reviewers with the credentials your task requires — clinicians, attorneys, CFAs, native linguists, or sensor-fusion specialists. Not a general-purpose crowd.
Measured quality, not promised quality
Every batch ships with agreement scores, golden-set F1, and per-class accuracy. If quality regresses, you see it before the data lands.
Security & compliance by default
SOC 2-aligned operations, signed NDAs per project, and customer-controlled deployments (VPC, on-prem, air-gapped) on request.
Senior program management
You get a named program lead who owns delivery End-to-End — not a ticket queue. Your ML team stops managing the vendor.
Built to integrate, not to lock you in
Guidelines, tools, and data are yours. We plug into your annotation tool or bring our own — whichever maximizes throughput and quality.
Real model-lift focus
Success is measured in downstream model metrics, not labels delivered. We track lift per data sprint and adjust strategy when the curve flattens.

Frequently asked questions
We routinely handle multilingual catalogs, leveraging a network of native-speaking linguists across more than 40 languages. This ensures that localization is accurate and culturally nuanced, preserving brand voice and product details.
Our approach to scaling for millions of SKUs employs a refined, blended pipeline. We initiate with model-assisted pre-labeling, leveraging AI to automatically process vast datasets and assign initial annotations.
Multimodal annotation is a core competency, encompassing both image and text data.
Most engagements progress from kickoff to the first labeled batch within one to two weeks, although exact timing depends on how specialized the workforce must be.
Our pricing is meticulously structured on a per-project basis, offering full transparency through a detailed breakdown of costs.
We support deployment configurations within your controlled Virtual Private Cloud (VPC), on-premise environments, or air-gapped systems when data sensitivity mandates strict isolation.
Upon project completion, full ownership of the data and all associated intellectual property rights transfer to your organization.
Production datasets often require ongoing maintenance to ensure model efficacy. Our approach involves establishing continuous data programs that incorporate scheduled refresh cycles.
