Xiaozhong Liu

Dr. Xiaozhong Liu is an Associate Professor at School of Informatics, Computing, and Engineering, Indiana University Bloomington. His research interests include information retrieval, natural language processing, text/graph mining, digital library, metadata, and computational social science. His dissertation at Syracuse University (advisor Dr. Elizabeth D. Liddy) explored an innovative ranking method that weighted the retrieved results by leveraging dynamic community interests. His research developed an enhanced understanding of the scholarly network from a topical content perspective and investigated the use of full-text citation data to improve the overall recommendation ranking performance. Meanwhile, the proposed algorithms/system help students and scholars understand the challenging scientific publications and formulas. He proposed Full-text Citation Analysis, Scientific Information Understanding, and Cross-Social Media Mining projects... He also serves as the NLP Director at Alibaba DAMO Academy...
