# E-commerce Visual Matching Dataset

**Candidate match workflow dataset for product identity resolution, visual similarity, and review decision fields.**

A public-safe workflow preview of how Octoparse structures AI-assisted product matching pipelines for e-commerce and pricing teams. Every row represents a candidate pair evaluation — the same structure delivered to production clients.

Built by **[Octoparse Managed Data Service](https://www.octoparse.com/data-service/ai-visual-product-matching)** — managed web data pipelines for pricing intelligence and catalog teams.

> **Public-safe proof, not raw client data.** Source product IDs, retailer names, and image URLs have been masked or replaced with workflow tokens. This dataset is designed to show schema, field naming, QA context, and delivery format. Final production pipelines are scoped per customer and delivered under agreed terms.

### Enterprise Data Pipelines & Production-Grade Delivery

> This dataset is a curated, static sample provided by **[Octoparse Managed Data Service](https://www.octoparse.com/data-service)**.
> If your organization requires:
> - **Real-time automated updates**: Daily/Hourly feeds via API, Snowflake, AWS S3, or BigQuery
> - **Custom schema alignment** and production-grade anti-bot operations with 99.9% SLA-backed delivery
> - **Compliance-aware data delivery workflows** for public or properly authorized data, with support for GDPR/CCPA-aligned requirements
>
> **[Request a Custom Data Pipeline Workshop on Octoparse Data Service](https://www.octoparse.com/data-service)**

## Why This Dataset

Most product matching datasets available publicly are:
- **Flat and unstructured** — raw scraped listings without match decisions or rejection reasons
- **Benchmark-only** — built for model accuracy evaluation, not production workflow design
- **Missing QA context** — no confidence scores, reject reasons, or review routing logic

This dataset is different:
- **Candidate-pair schema** — each row is a source↔candidate evaluation, not a raw product listing
- **Match decisions included** — `match_status` captures the final output: accepted, rejected, or needs review
- **Reject reasons structured** — `reject_reason` shows why candidates were declined, enabling workflow analysis
- **Review notes present** — `review_note` captures QA context for borderline cases

### Core Fields

| Field | Type | Description |
|---|---|---|
| `source_product_id` | string | Masked identifier for the source product being matched |
| `candidate_product_id` | string | Masked identifier for the candidate product retrieved |
| `similarity_score` | float | Visual similarity score (0.0–1.0) from image matching model |
| `match_status` | string | Final decision: `accepted`, `rejected`, `needs_review` |
| `reject_reason` | string | Structured rejection category (null for accepted matches) |
| `review_note` | string | QA annotation for borderline or escalated candidates |

### `match_status` Values

| Value | Meaning |
|---|---|
| `accepted` | Candidate confirmed as the same or equivalent product |
| `rejected` | Candidate declined — see `reject_reason` |
| `needs_review` | Low confidence or conflicting signals — routed to analyst |

### `reject_reason` Categories

| Value | Meaning |
|---|---|
| `different_product` | Visually similar but distinct item |
| `different_variant` | Same product line, incompatible variant (size, color, spec) |
| `image_quality` | Source or candidate image insufficient for visual comparison |
| `low_confidence` | Similarity score below threshold with no confirming text signal |
| `title_conflict` | Image match but title/model-number contradiction |

---

## Quick Start

```python
import pandas as pd

df = pd.read_csv("visual_matching_workflow_sample.csv")

# Output bucket distribution
print(df["match_status"].value_counts())

# Rejection reason breakdown
rejected = df[df["match_status"] == "rejected"]
print(rejected["reject_reason"].value_counts())

# Similarity score distribution by decision
print(df.groupby("match_status")["similarity_score"].describe())

# Review queue — candidates needing human judgment
review_queue = df[df["match_status"] == "needs_review"]
print(f"{len(review_queue)} candidates routed to review")

# Accepted matches with high confidence
high_confidence = df[(df["match_status"] == "accepted") & (df["similarity_score"] >= 0.85)]
print(f"{len(high_confidence)} high-confidence accepted matches")
```

## What This Dataset Answers

**What is AI visual product matching?**
Visual product matching is the process of determining whether products listed across different retailer, marketplace, or competitor sites refer to the same item — using image similarity, text signals, and structured QA to produce an explainable match decision.

**Why does matching require more than image similarity?**
A high `similarity_score` alone is not sufficient. Products can look nearly identical but differ in model number, size, or spec. This workflow combines visual similarity with title validation and structured rejection reasons to produce decisions a pricing team can act on.

**What does a production matching output look like?**
This dataset shows the candidate-pair output format: each row is a source↔candidate evaluation with a similarity score, a match decision, a rejection reason if applicable, and a review note for borderline cases. This is the data contract delivered to production clients.

**How should downstream systems consume match decisions?**
- `accepted` rows feed directly into pricing intelligence or catalog deduplication
- `needs_review` rows route to an analyst queue for QA
- `rejected` rows with `reject_reason` can be used to tune retrieval thresholds

---

## Use Cases

### 1. Competitor Price Monitoring
Use accepted matches to build a cross-retailer price comparison table. `source_product_id` maps your catalog; `candidate_product_id` maps competitor listings. Accepted rows give you the joined dataset for price delta analysis.

### 2. Catalog Deduplication
Use `match_status = accepted` + `similarity_score` to identify duplicate or equivalent listings in a multi-source product catalog. `reject_reason = different_variant` helps separate true duplicates from variant siblings.

### 3. Matching Pipeline Evaluation
Use the full candidate-pair schema to design or evaluate your own matching pipeline. The `reject_reason` distribution shows where retrieval methods fail and where visual scoring succeeds.

### 4. Review Queue Design
Use `needs_review` rows + `review_note` to design analyst escalation logic. The notes show what information a QA analyst needs to resolve low-confidence candidates.

### 5. AI Model Training Data Structure
Use the schema as a template for structuring your own training data. The `similarity_score` + `match_status` pairing provides a label structure for fine-tuning multimodal classifiers.

## Data Limitations

| Limitation | Detail |
|---|---|
| Public-safe only | Source and candidate IDs, retailer names, and image URLs are masked |
| Workflow preview | This is not a complete production export. Row count is representative, not exhaustive |
| No raw images | Image URLs are not included in this public release |
| Score calibration | `similarity_score` thresholds are illustrative; production thresholds are scoped per client catalog |
| Not for benchmarking | Do not use to claim measured model accuracy on real catalog data |
