Introduction

Wei Gao is a Senior Lecturer of Information Systems in the School of Information Management, Victoria University of Wellington in New Zealand. Before joining Victoria, he was a Scientist in Qatar Computing Research Institute in Qatar from 2011 to 2017, a Research Assistant Professor in the Chinese University of Hong Kong from 2010 to 2011, and a Research Fellow in the Institute for Infocomm Research in Singapore in 2010. During his PhD study, he conducted research by visiting natural language computing group in Microsoft Research Asia in 2006 and 2007.

He has strong interests in applying machine learning approach for solving a wide spectrum of real-world research problems in big data era which intersect information retrieval, natural language processing, social computing, and data mining. He has published over 60 papers and articles in the major international conferences and journals such as ACL, EMNLP, SIGIR, CIKM, WSDM, IJCAI, ACM TOIS, ACM TIST, KAIS, SNAM, etc. He served in the program committees of a good number of conferences and worked as the reviewer for top-tier journals in these relevant research areas. He also served as the workshop co-chair of BigComp 2016, the session chair in ASONAM 2015, the area co-chair in NLPCC2015, and the tutorial co-chair in IJCNLP 2011.
