Research Interests
theoretical and computational pragmatics (especially conversation analysis), constructions and frames, machine learning

I am a PhD candidate in linguistics with a background in data science concerned with developing new tools for spoken dialog systems. My research focuses on describing and modeling pragmatic and phonological aspects of constructions (cxn) in human speech and their application in the field of spoken language understanding. More specifically, my PhD thesis is concerned with investigating and modelling the use of ‘causal’ discourse markers (janwai, yinwei, because) in a corpus of naturally-occurring everyday speech that I built. Drawing on insights from interactional and cognitive linguistics, the project aims to provide both (i) theoretical insights into how these discourse marker constructions are used in the real world and (ii) practical insights useful for designing open-domain spoken dialog systems and discourse parsers.

Part of this project is the compilation of a video corpus of Cantonese naturally-occurring speech that will be made available soon (see mycancor).

I mainly work with Chinese languages (Mandarin and Cantonese).
