Research Interests

My past research experience is mainly in the fileds of natural language processing and information retrieval, including personalized search,cross-modal retrieval and pre-trained language models. My current research interests are several topics in natural language processing and machine learning, including multimodal deep learning (e.g., multimodal representation learning), prompt engineering, and explainable artificial intelligence.

Research Experience

Research on Contrastive Learning for Personalized Product Searh

working with Jiongnan Liu and Prof.Zhicheng Dou

• Proposed a contrastive learning method fo personalized product search, consisting of the pre-train stage using data augmentation strategy and the fine-tune stage for searching task.

Research on Explainability of Case Law Retrieval

working with Luxi Chen, Jie Chen, Ning Lin , Qi Liu and Prof.Zhicheng Dou

• Proposed a pipeline-based framework utlizing pre-trained models for case law retrieval, including three modules of extracting feature sentences, computing matching matrices and classifying results.
