Dynamics in the phonological encoding of bilingual speech production [pdf]

This is my undergraduate thesis. I used a picture-naming paradigm to test whether the phonological mapping status of cognates in Mandarin and Shanghai Dialect would take an effect on the speech production process and found a cognate facilitation effect when the phonological forms of the cognates match the basic mapping rules regardless of the discrepancy of their phonetic forms.

Agenda-based Parser for Multiple Context-free Grammars [Github]

This is an agenda-based parsing Python module for multiple context-free grammars a full test suite implemented in Pytest. Multiple context-free grammar is a class of grammar that is strictly more expressive than context-free grammar.

Retrieval-Augmented Event Extraction [Github]

I conducted extensive experienments on GPT-4o and Claude Sonnet 3.5's capability of extracting event roles from the FAMuS dataset using various prompt strategies. Using the CEAF family of metrics, the results suggest that large language models can not extract roles accurately and truthfully, indicating that they do not have human-level event understanding. However, after some post-processing, the extracitons can still be useful for some applications.
