Current Research

• Semantic Web and Knowledge Management: The goal in this research area is to develop semantic data extraction, expression, storage, retrieval and visualizing technologies to build and maintain a knowledge base on a domain. In particular, firstly, the research seeks to design a semantic data model and storage technology for semantic data and develops some technologies to store large semantic data that achieves efficient storage utilization, supports fast query operations, and supports the addition of new semantic data. Secondly, the research tries to develop information extraction and data integration technologies for semantic data acquisition. Furthermore, we seek to develop friendly semantic data retrieval, evaluation and visualization technologies which try to provide high-quality search results and visualize semantic association among data. We have developed SemreX, which is a semantic based literature sharing system and manages meta data of more than 1 million literatures. The eldest SemreX was a Semantic Peer-to-Peer Scientific References Sharing System and developed in 2004. Now SemreX adopted a centralized architecture and foucsed on new functions based on semantic. Now, SemreX provides the following functions: automation extraction of meta data of literature, semantic associate based storage, literature classification and ranking, literature retrieval, emerging trends detection and semantic data vislualization etc. We are now developing latest SemreX. The latest SemreX shows some new features, such as high efficiency storage in semantic data, quick response and friendly user-interface and so on. In this field, we also research technology and system for large scale data management due to huge amount of semantic data in RDF available online and developed triple stores, such as DBLink and TripleBit.
• Distributed Computing Technology and System: Currently, the research mainly focuses on grid and cloud computing. Based on grid platform, the research develops middleware infrastructures for grid applications. With the help of middleware infrastructure in grid environment, sharing resources and cooperating among resources and users can be supported efficiently and flexibly. The goal of the research is to simplify the development and deployment of grid applications, and make it possible that grid application can be constructed and deployed on demand. In this research field, we developed Grid Based Geographic Information Co-Mark System and Grid based System Simulation Platform. Currently, we are developing distributed storage system - ppStore which utilizes storage services available on Web.
• Performance Evaluation & Optimization: Due to the advantage of virtualization technology, virtualization technology is experiencing a resurgence of interest and is being used in a variety of places, ranging from the data center to the desktop. This has spurred great advances in processor and memory virtualization in hardware and virtualization software. The growing popularity of virtualization technology motivates deeper investigation of the performance implications of virtualiza-tion. The goal in the research area is to develop performance evalaution technology and benchmark, perforamnce optimization technology. We developed vBench for evaluating CPU, I/O, and network in virtual machine environments. Moreover, since server consolidation is one of important applications of virtualization technology, we developed VSBechmark for evaluating performance in server consolidation. Now, we focus on high performance Network I/O and Disk in virtualization technology.
