He is a Fellow of ACM and IEEE. His book "Data Mining: Concepts and Techniques" (Morgan Kaufmann) has been used worldwide as a textbook.
Mining Heterogeneous Information Networks By Exploring the Power of Links
Many objects in the real world are interconnected, forming complex information networks. There have been a lot of studies on mining homogeneous information networks where objects and links are either treated as of the same type, such as friends linking with friends, or treated indiscriminatively, without structural or type distinction. However, real-world objects and links often belong to distinct types, such as students, professors, courses, departments, teach and advise in a university network, and such typed networks form structured, heterogeneous information networks.
