Crowdsourcing in Information and Knowledge Management

2014 CIKM Tutorial

Lei Chen (HKUST), Dongwon Lee (Penn State), and MeihuiZhang (SUTD)



As a novel computation paradigm, crowdsourcing is being actively pursued in diverse academic disciplines. Within computer science, many sub-fields have embraced the concept of crowdsourcing with open arms and applied the concept to solve many challenging problems. Communities relevant to the CIKM conference such as Database, Information Retrieval, and Data Mining are no exception to this phenomenon and there have been many exciting new results using crowdsourcing appearing in recent literature. This tutorial, after gentle introduction on the history and concept of crowdsourcing, provides the overall landscape of crowdsourcing research in CIKM communities, with the particular focus on some of latest crowdsourcing research in Database field.

Dongwon Lee
, Associate Professor, Penn State University, USA (dongwon@psu.edu)

Dongwon Lee is currently an associate professor in the College of Information Sciences and Technology (a.k.a. iSchool) of the Pennsylvania State University, USA. He obtained his Ph.D. in Computer Science from UCLA in 2002. From 1995 to 1997, he has also worked as a programmer at AT&T Bell Labs.  Working mostly on the issues arising in the management and mining of diverse forms of data (e.g., relational records, documents, XML, and social media), he has (co-)authored over 130+ scholarly articles in selective publication outlets in Databases and Data Mining. He has also served as a PC member for major venues such as SIGMOD, VLDB, ICDE, CIKM, KDD, SDM, WWW, IJCAI, WSDM, and JCDL. Further details of his research can be found at: http://pike.psu.edu/

, Assistant Professor, SUTD, Singapore

Meihui Zhang is currently a Research Fellow at National University of
Singapore and will join Singapore University of Technology and Design as an Assistant Professor in August. She did her Ph.D. in Computer Science at National University of Singapore and obtained her B.E. in Computer Science from Harbin Institute of Technology, China. Her research interests mainly focus on database issues. Her Ph.D. thesis was on database exploration and schema extraction. She also works on crowdsourcing, massive data integration and spatio-temporal databases.
