My research interest lies in the following database topics: ata Curation (Data Annotation, Data Integration, and Data Organization), LLMs, and RAG. I have prepared slides introducing my research.

We constructed a comprehensive RAG benchmark and hosted the KDD Cup competition.

[LLM, RAG, Data Organization]

We conducted an extensive evaluation of SOTA LLMs on taxonomies.

[LLM, Data Organization]

We proposed a novel cross-domain-aware worker selection with training approach for crowdsourced data labeling.

[Data Annotation]

We defined a novel named entity schema for related and sub-related table discovery and alignment for enhancing the annotation quality of column semantic types.
