摘要：In this talk, I will first introduce three research topics I am

doing currently: XML data management, Similarity search and cloud data

management. Then I will introduce our new work: top-k,m query

processing. Suppose we are given a set of groups where each attribute

in one group is associated with a list whose tuples are equipped with

IDs and scores. The goal is to return the top-k combinations of

attributes with the highest overall scores from the respective top-m

scores from lists. Top-k,m queries are different from regular top-k

queries in nature and useful in various emerging scenarios, including

recommendation systems, query refinement and medical data mining.
