Welcome to the Data Systems Lab (Big data Lab)

Welcome to the Data Systems Lab (Big Data Lab) at the POSTECH. Our data systems lab focuses on STAR (namely, Systems, Theory, and ARtificial intelligence) supported by major grants such as Star Lab. We have been endeavoring to solve challenging and real problems in computer/data science.

Our goal is to build scalable, intelligent Big data systems that effectively 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 distributed graph engines such as TurboGraph/TurboGraph++/iTurboGraph. We are also building an intelligent system to interact with humans through a natural language interface to the database

We are currently hiring interns for this summer (연구 참여학생 모집). This is an amazing opportunity for undergrads to experience world-class research in Big Data and prepare for possible graduate school applications. You could be a rising-STAR of the future if you stand out in our field [detailed info].

We are proud of strong publication records in top database venues such as SIGMOD/VLDB (16 SIGMOD/VLDB papers by our group for the past 5 years), significantly contributing to make the Korean database community one of the strongest communities worldwide. Many of our alumni work for top notch companies including Facebook, Oracle, SAP, Microsoft, and Amazon. We have been closely collaborating with Oracle Labs and SAP for many years.

We are looking for intern students this summer. There are several exciting projects including NL2SQL, development of an open source, distributed graph DBMS, data management for AI, AI for data management, and so on. For those who are interested in database systems, we also give opportunities for in-depth study on database systems.
