## What it is
A collection of deep learning models for Chinese information extraction, including named entity recognition with IDCNN or biLSTM+CRF and relation extraction with biGRU+2ATT. It is organized as separate sub-projects with their own documentation, implemented in Python with TensorFlow.

## Use cases
- extract named entities from Chinese text
- recognize person, organization and location names in Chinese documents
- extract relations between entities in Chinese sentences
- train a Chinese NER model with biLSTM+CRF
- run Chinese relation extraction with attention-based biGRU
- build an information extraction pipeline for Chinese text

## When to choose
- you need Chinese-specific NER or relation extraction with classic deep learning architectures
- you want trainable TensorFlow models for Chinese entity and relation extraction
- you need reference implementations of IDCNN+CRF or biGRU+attention for Chinese NLP

## When to avoid
- you need production-grade maintained software with a license and active support
- you need multilingual or English information extraction
- you want transformer-based or LLM-era extraction models out of the box
