ETIM AI Classifier - Automated Product Classification Tool | Sivert Kjøller Bertelsen

The Challenge

Electrical product data comes in unstructured formats - PDFs, datasheets, images. Converting this into standardized ETIM classifications requires:

Deep knowledge of ETIM's 5,640 product classes
Manual reading of technical specifications
Understanding of 159 product groups and hierarchies
Hours of work per product

Manual classification doesn't scale.

The Solution

The ETIM AI Classifier uses GPT-4 to automatically classify products from any source:

✅ PDF datasheets - Extract and classify technical specs
✅ Product images - Analyze photos using Vision API
✅ Text descriptions - Process natural language
✅ JSON data - Structured product information

Result: Complete ETIM classification in 30-60 seconds.

How It Works

1. Input Processing

Upload any format:

PDFs are parsed for text extraction
Images analyzed with GPT-4 Vision
Text and JSON processed directly

All inputs normalized to unified format.

2. Smart Classification

Hierarchical approach:

Step 1: AI selects from 159 ETIM groups
        ↓
Step 2: AI narrows to ~40 relevant classes
        ↓
Step 3: AI picks exact ETIM class
        ↓
Step 4: Extract 20-50 feature values

This narrows from 5,640 classes to 1 accurate match.

3. Feature Extraction

AI reads the document and extracts values for ETIM features:

Validates against ETIM API - Uses official feature definitions
Confidence scoring - Each value includes certainty percentage
Smart suggestions - AI infers missing values from context
ETIM compliance - Respects allowed values and units

Example extraction:

Feature	Value	Confidence	Source
Nominal voltage	230V	95%	Datasheet page 2
IP rating	IP20	88%	Description
Number of poles	3	90%	Product specs

AI Model: GPT-4o-mini for fast, cost-effective classification

ETIM Data:

Official ETIM API for feature definitions
Offline database (ETIM 10.0) with 5,640 classes
159 product groups

Architecture:

Next.js 15 with Server-Sent Events
Vercel deployment (5-minute timeout)

Accuracy & Cost

Per classification:

~8,000 tokens
$0.0024 USD
30-60 seconds

Accuracy:

Group selection: ~95%
Class selection: ~85%
Feature extraction: 60-80% of features found

The hierarchical approach ensures high accuracy by narrowing from 5,640 classes to ~40 candidates before final selection.

"The key insight is using ETIM's hierarchical structure. Instead of asking AI to pick from 5,640 classes, we narrow it down step by step. This matches how humans classify products - you start broad and get specific."

Example: Circuit Breaker Classification

Input: Schneider Electric MCB datasheet PDF

Process:

AI identifies: "Miniature circuit breaker"
Group: EG000020 (Circuit breakers and fuses)
Class: EC000042 (Miniature circuit breaker)
Extracts 9 features including poles, current rating, voltage

Output:

{
  "class": "EC000042",
  "confidence": 85,
  "features": {
    "poles": "3",
    "rated_current": "20A",
    "rated_voltage": "230V",
    "release_characteristic": "C"
  }
}

Time: 45 seconds Cost: $0.0024
