 ## 📝 What is GraphGen?
 
-GraphGen is a framework for synthetic data generation guided by knowledge graphs.
+GraphGen is a framework for synthetic data generation guided by knowledge graphs. 
+
+It begins by constructing a fine-grained knowledge graph from the source text，then identifies knowledge gaps in LLMs using the expected calibration error metric, prioritizing the generation of QA pairs that target high-value, long-tail knowledge.
+Furthermore, GraphGen incorporates multi-hop neighborhood sampling to capture complex relational information and employs style-controlled generation to diversify the resulting QA data.
