Welcome to the Database & Data Mining Lab (Big Data Lab) at the POSTECH. We have been focusing on big data, databases, mining, and AI related research. We are trying to publish solid papers in prestigious top-tier database (SIGMOD, VLDB, ICDE) and data mining/machine learning conferences (SIGKDD, ICML, NIPS). 

Our goal is to build scalable, intelligent Big data systems that effectivly and efficiently deal with Big data. Most of Big data is unstructured data, and thus, it is difficult to handle. We are building a system for converting unstructured data into semi-structured data in a graph form so that it can be easily handled in our parallel graph engine. We are also building an intelligent system to interact with humans.
