FIELDS of SPECIALIZATION

Dr. Chung has been developing a new clustering system that clusters social media data, such as Twitter messages, based on their textual content and displays the clusters and their locations on the map. This system uses two-phase clustering, composed of micro-clustering and macro-clustering. The online micro-clustering phase incrementally creates micro-clusters that represent enough information about topics occurring in the test stream. The off-line macro-clustering phase clusters micro-clusters for a user-specified time interval. This system can be used to provide at-a-glace information to be displayed throughout the evolution of a crisis.
Dr. Chung investigated a new two-step algorithm for anomaly detection in time-series data. The first step uses a simple data forecasting model which is fast with high recall but potentially low precision, whereas the second step uses a complex data forecasting model which is slower but more accurate. The first model initially labels each data value. When an anomaly is reported by the first model, the second model relabels that data value, verifying or correcting the initial lable. This verification step reduces the false positive rate of the first step. This method provides accurate identification of anomalous data values as well as fast rejection of non-anomalous data values.
Dr. Chung investigated a new multi-scale 3D shape descriptor, based on the discrete orthogonal Tchebichef moments, for the characterization of 3D action pose shapes made of low-resolution point cloud patches. This shape descriptor consists of low-order 3D Tchebichef moments computed with respect to a new point cloud voxelization scheme that normalizes translation, scale, and resolution. The action recognition is built on the Naive Bayes classifier using temporal statistics of a `bag of pose shapes'. Our shape descriptor and action recognition method can be applied to LIDAR data.
Dr. Chung worked on various database issues, including distributed replicated data management, active database, heterogeneous multidatabase system, multimedia databases, and data mining. For heterogeneous multidatabase, a global schema integration scheme using the object-relational model has been proposed, and the semantics-based concurrency control of global transactions was also investigated. Parallel data mining algorithms were developed for text databases and transaction databases on a cluster of rack-mounted 9 Linux workstations interconnected by a Fast-Ethernet switch.
- For text databases, efficient document clustering algorithms were developed.
- For transaction databases, scalable association rule mining and sequence mining algorithms were developed.
Dr. Chung developed a Data Grid system using the Globus Toolkit on a 12-node Linux cluster, where each node is running Red Hat Linux Enterprise edition. This system is used for distributed data mining and for the integration of distributed databases. Role-based access control methods are also developed for the Data Grid system.
During 2000-2005, Dr. Chung was in charge of a NCR WorldMark 4850 parallel database machine, Teradata RDBMS, and Teradata Warehouse Miner. This system was granted by NCR in 2000, and equipped with 8 Xeon processors and a disk array.
Storage model, retrieval mechanism, and network delivery for multimedia information are investigated, and this project has been supported by NCR Corporation, Ohio State, and National Science Foundation.
Involved in a project of automatic video segmentation for content-based retrieval, as a visiting researcher at the Computer and Software Technology Lab of Electronics and Telecommunications Research Institute (ETRI) in Korea during 9/97--8/98.
Analyzed the performance of network I/O using Remote Procedure Calls (RPCs) of Distributed Computing Environment (DCE) in client-server information systems for LexisNexis Company.
Dr. Chung was the principal investigator of the research on clustering and parallel processing of databases, supported by National Science Foundation and Ohio State Research Challenge Grant.
Involved in the project of developing a parallel architecture and algorithms for very large data/knowledge bases, which was supported by AFOSR, as a research assistant for three years at Syracuse University.
Dr. Chung has graduated 10 Ph.D. and 24 M.S. students as the dissertation/thesis advisor.
