Domain And Use Case Diversity Sampling And Stratification

via “domain and use-case diversity sampling and stratification”

1M+ real user-AI conversations with demographic metadata.

Unique: Captures authentic domain diversity from real ChatGPT/GPT-4 users without synthetic prompt engineering, preserving natural distribution of use cases and user intents, though requiring post-hoc domain inference rather than explicit labels

vs others: More authentic domain diversity than synthetic instruction-tuning datasets, though less explicitly labeled and curated than purpose-built domain-specific corpora

via “domain-stratified text sampling and split management”

Dataset by HuggingFaceFW. 6,43,166 downloads.

Unique: Pre-computes stratified splits across web domains at dataset creation time, ensuring consistent domain representation in train/val/test without requiring custom sampling logic — most web corpora provide raw data without domain-aware split management

vs others: Enables domain-aware evaluation out-of-the-box, whereas raw Common Crawl requires manual domain classification and split creation
