Resume-ATS Score Dataset v1 (English)

Dataset Description

resume-ats-score-v1-en is a semantic similarity dataset designed for training sentence transformers to predict ATS (Applicant Tracking System) compatibility scores between resumes and job descriptions. This dataset enables fine-tuning models to understand the semantic alignment and matching quality between candidate profiles and job requirements.

Key Features

  • 📊 6.4K examples (5.1K train, 1.3K validation)
  • 🎯 Continuous ATS scores ranging from 18.3 to 90.7
  • 📈 Three-tier classification: No Fit, Potential Fit, Good Fit
  • 🔄 Sentence pair format ready for CosineSimilarityLoss training
  • ✅ High quality data with 90.5% quality score
  • 🌍 Diverse job categories across multiple industries

Dataset Structure

Data Format

Each example contains:

Column Type Description
text string Combined resume and job description: resume [SEP] job_description

original_label string Categorical label: "No Fit", "Potential Fit", or "Good Fit"

Data Splits

Split Examples Percentage
Train 5,099 80%
Validation 1,275 20%
Total 6,374 100%

Score Distribution

Metric Value
Minimum Score 18.3
Maximum Score 90.7
Mean Score 47.2

Potential Fit (Score: 53.9):

Resume: "Sales Associate with customer service experience, Windows/Linux knowledge..."
Job: "Software Developer position requiring C++, Qt, web development..."
ATS Score: 53.9
Label: Potential Fit

No Fit (Score: 24.3):

Resume: "Web Developer with PHP, JavaScript, CSS experience..."
Job: "Software Engineering Manager requiring 5+ years management, team leadership..."
ATS Score: 24.3
Label: No Fit

Source Data

This dataset is derived from the Resume-Job Description Fit dataset (cnamuangtoun/resume-job-description-fit).

Data Generation Process

  1. Source Extraction: Resume-job pairs extracted from base dataset
  2. Quality Filtering:
    • Removed empty texts (0 found)
    • Removed duplicates (2 removed)
    • Filtered very short or very long texts
  3. Score Calculation: ATS compatibility scores computed based on semantic similarity
  4. Normalization: Text cleaned and normalized
  5. Categorization: Scores categorized into No Fit, Potential Fit, Good Fit
  6. Train/Val Split: 80/20 split for model training and evaluation

Quality Metrics

  • Empty Texts: 0 (100% complete)
  • Duplicates Removed: 2
  • Overall Quality Score: 90.45%
  • Average Text Length: ~8,480 characters per example

Intended Use

Primary Use Cases

  1. ATS Score Prediction: Train models to predict compatibility between resumes and jobs
  2. Semantic Similarity Learning: Fine-tune sentence transformers for resume-job matching
  3. Resume Ranking: Rank candidates based on job description fit
  4. Job Recommendation: Recommend suitable jobs for candidate profiles

Model Training

This dataset is designed for training with CosineSimilarityLoss using sentence transformers:

Recommended Base Models:

  • jinaai/jina-embeddings-v2-base-en (used for nbk-ats-semantic-v1-en)
  • sentence-transformers/all-MiniLM-L6-v2
  • sentence-transformers/all-mpnet-base-v2
  • Any sentence transformer model

Expected Performance: Models trained on this dataset typically achieve RMSE < 8.0 for ATS score prediction.

Example Training Code 

from sentence_transformers import SentenceTransformer, losses, InputExample
from torch.utils.data import DataLoader
from datasets import load_dataset
import pandas as pd

# Load dataset
dataset = load_dataset("0xnbk/resume-ats-score-v1-en")
train_df = pd.DataFrame(dataset['train'])

# Prepare training examples with normalized scores (0-1 range)
train_examples = []
for _, row in train_df.iterrows():
    # Split resume and job description
    resume, job = row['text'].split(' SEP ')
    # Normalize score to 0-1 range for CosineSimilarityLoss
    normalized_score = row['ats_score'] / 100.0
    train_examples.append(
        InputExample(texts=[resume, job], label=normalized_score)
    )

# Load base model
model = SentenceTransformer('jinaai/jina-embeddings-v2-base-en')

# Define loss and dataloader
train_dataloader = DataLoader(train_examples, shuffle=True, batch_size=16)
train_loss = losses.CosineSimilarityLoss(model=model)

# Train
model.fit(
    train_objectives=[(train_dataloader, train_loss)],
    epochs=4,
    warmup_steps=100,
    optimizer_params={'lr': 2e-5},
    output_path='./ats-semantic-model'
)

# Save
model.save('./ats-semantic-model')

Inference Example 

from sentence_transformers import SentenceTransformer
from scipy.spatial.distance import cosine

# Load trained model
model = SentenceTransformer('./ats-semantic-model')

# Test resume-job matching
resume = "Software engineer with 5 years Python, Django, React experience"
job_good_fit = "Senior Python Developer requiring Django framework expertise"
job_poor_fit = "Registered nurse position requiring ICU patient care"

# Encode
resume_emb = model.encode(resume)
good_fit_emb = model.encode(job_good_fit)
poor_fit_emb = model.encode(job_poor_fit)

# Calculate ATS scores (cosine similarity * 100)
good_fit_score = (1 - cosine(resume_emb, good_fit_emb)) * 100
poor_fit_score = (1 - cosine(resume_emb, poor_fit_emb)) * 100

print(f"Good fit ATS score: {good_fit_score:.1f}")  # Expected: 70-90
print(f"Poor fit ATS score: {poor_fit_score:.1f}")  # Expected: 20-40

Dataset Statistics

Size Metrics

  • Total size: ~51MB (CSV format with text pairs)
  • Average text length: ~8,480 characters per example
  • Average resume length: ~4,500 characters
  • Average job description length: ~3,980 characters
  • Token count: ~7M tokens (estimated with BERT tokenizer)

Score Distribution Analysis

The dataset shows a realistic distribution of resume-job matching:

  • Peak at low scores (20-30 range): Many resumes don't closely match specific jobs
  • Second peak at high scores (70-90 range): Well-matched professional pairs
  • Moderate scores (40-70 range): Partial skill overlap or transferable experience

This distribution reflects real-world ATS screening where most candidates are filtered out, some show potential, and a smaller portion are strong matches.

  • Epochs: 4
  • Batch Size: 16
  • Learning Rate: 2e-5
  • Warmup Steps: 100
  • Hardware: NVIDIA A6000 48GB GPU
  • Training Time: ~30 minutes

Limitations and Considerations

Known Limitations

  1. Score Subjectivity: ATS scores are calculated algorithmically and may not reflect human judgment
  2. Domain Coverage: Dataset may not cover all niche industries or specialized roles
  3. Language: Currently only English language support
  4. Text Length: Long resumes and job descriptions (average ~8,500 chars) may challenge some models
  5. Temporal Bias: Reflects job market terminology as of 2024-2025

Ethical Considerations

  • Bias: May reflect biases present in resume screening and job posting practices
  • Privacy: No personally identifiable information (PII) included
  • Fairness: Users should validate model fairness across protected characteristics
  • Transparency: Scores are algorithmically derived, not human-annotated
  • Responsible Use: Should supplement, not replace, human judgment in hiring decisions
