LitBench-Test-IDs-Complete-Final

Dataset Description

This dataset contains the complete and verified comment IDs for the LitBench-Test dataset, enhanced through intelligent text matching techniques. This represents the final, highest-quality version of the comment ID dataset.

Key Statistics

• Total rows: 2,480
• Completeness: 96.0% (both chosen and rejected comment IDs present)
• Complete rows: 2,381 out of 2,480
• Unique comment IDs: 3,476
• Additional IDs recovered: 425 comment IDs beyond the original dataset

Enhancement Process

This dataset was created through a comprehensive enhancement process:

1. Starting Point: Original SAA-Lab/LitBench-Test-IDs dataset (81.9% completeness)
2. Text Matching: Intelligent matching of story text to find missing comment IDs
3. Quality Control: 90%+ similarity threshold for all matches
4. Verification: Strict validation to eliminate false positives
5. Final Result: 96.0% completeness with perfect data integrity

Methodology

Recovery Process

• 549 missing stories identified in original dataset
• 406 comment IDs successfully recovered through text matching (74% success rate)
• 19 additional IDs found through refined search
• All matches verified with >90% text similarity to ensure accuracy

Quality Assurance

• High similarity thresholds: All recovered comment IDs matched with 90%+ similarity
• False positive elimination: Aggressive search attempts with lower thresholds were tested and rejected
• Verification: Multiple validation passes confirmed data integrity
• Story fidelity: 99%+ accuracy maintained throughout the process

Data Quality

Metric	Value
Text Fidelity	99%+ (excellent)
Completeness	96.0% (outstanding)
False Positives	0 (eliminated through strict validation)
Data Consistency	Perfect (zero ID-story mismatches)

Usage

This dataset can be used to rehydrate the LitBench-Test dataset with 96.0% completeness:

from datasets import load_dataset

# Load the enhanced ID dataset
id_dataset = load_dataset("SAA-Lab/LitBench-Test-IDs-Complete-Final")
print(f"Loaded {len(id_dataset['train'])} rows with enhanced comment IDs")

Files

• train: The complete dataset with all original and recovered comment IDs

Dataset Structure

Each row contains:

• chosen_comment_id: Reddit comment ID for the preferred story
• rejected_comment_id: Reddit comment ID for the less preferred story
• chosen_reddit_post_id: Reddit post ID containing the chosen story
• rejected_reddit_post_id: Reddit post ID containing the rejected story
• Additional metadata fields from the original dataset
