Xuhui Zhou

I am an incoming PhD student in the School of Interactive Computing at Georgia Tech, advised by Diyi Yang. I am interested in socially intelligent human language technology.

Specifically, I focus on how to enable NLP to better navigate social contexts. Nowadays, NLP models are strong in terms of benchmark performance. However, they produce hatespeech, contain social biases, behave undesiredly, and etc., which hurt, divide, and disappoint people.

Previously, I interned at Apple as a machine learning engineer. I was a CLMS student at the University of Washington (UW) advised by Noah Smith. I got my bachelor degree in Statistics at Nanjing University (NJU).

Text alignment finds application in tasks such as citation recommendation and plagiarism detection. Existing alignment methods operate at a single, predefined level and cannot learn to align texts at, for example, sentence and document levels. We propose a new learning approach that equips previously established hierarchical attention encoders for representing documents with a cross-document attention component, enabling structural comparisons across different levels (document-to-document and sentence-to-document). Our component is weakly supervised from document pairs and can align at multiple levels. Our evaluation on predicting document-to-document relationships and sentence-to-document relationships on the tasks of citation recommendation and plagiarism detection shows that our approach outperforms previously established hierarchical, attention encoders based on recurrent and transformer contextualization that are unaware of structural correspondence between documents.
