The members of the Intelligent Data Systems (IDS) Lab. conduct research in the areas of context-aware recommendation, big data management, software issues in smart reality and semantic technologies.

The Lab. is led by professor Sang-goo Lee and consists of graduate students under his supervision. IDS Lab. receives research funds from various organizations including the National Research Fund (NRF), the Brain Korea 21 (BK21) research project, and a number of private companies including Samsung, SKT, KT and Bell Labs Seoul.

The Lab leads collaborative efforts between SNU and Samsung Electronics through the Center for Intelligent Computing (CIC), which is a joint SW research institute between SNU and Samsung.
