Our NLU datasets belong to pure text corpus, independent of ASR/TTS audio data, focusing on intent recognition, entity extraction, semantic parsing, contextual understanding and dialogue comprehension. Covering daily conversation, business consultation, finance, medical, legal and vertical industry texts, all corpus is manually refined annotated by linguistic experts.
We standardize intent classification, entity tagging, semantic relationship annotation and context logic labeling, with multilingual and cross-regional sample layout to adapt global LLM training demands. The dataset features rigorous logic, clear semantics and complete context correlation, avoiding ambiguous and low-quality text.
