https://www.tkl.iis.u-tokyo.ac.jp/Our Lab has focused on completely novel and surprising research on system software, advanced applications,hardware and algorithms, which is the basis of the technology for handling large quantities of data. We havebeen developing high performance database engine based on a novel out-of-order execution principle, ultralarge-scale cyber space mining systems, 100 petabyte-scale global environment information system based on
database engineering, and natural language processing for understanding society trend and our thought.

Development of High Performance Database Engine for Big Data Era
Our research group has been developing Ultrafast Database Engine based on anovel out-of-order execution principle. This new database engine has thecapability to achieve significant performance boosting for analytical queries in
the Big Data era. The group has also been constructing an experimental systemof next-generation strategic social services (cyber physical services) to clarify
effectiveness of the new database engine.

Ultra-large-scale Cyber-Physical Space Analysis System
Our lab has continuously collected Japanese Web pages since 1999 and hasconstructed a Web archive system including about tens of billions of URLs,
billions of blog articles, and tens of billions of tweets. Based on this peta scalearchive, we are developing structural, contents, and temporal analysis systems
including information diffusion extraction, inter-media comparison, and realtime deep text analysis. The cyber space information is integrated with physicalspace information such as mobility data for traffic analysis. Results of analysis
can be interactively visualized on a large-scale high-resolution display wall.

100 Petabyte Scale Global Environmental Information Fusion
We have been developing a large scale global environmental information
fusion system for data integration and analysis that includes the supporting
functions of life cycle data management, data search, information
exploration, scientific analysis, and partial data down-loading.

Natural Language Processing for Reading Social Bigdata
Aiming to understand human mind and the real world from text and aid ourcommunication and language understanding, we study on natural language
processing that process text efficiently and accurately with computers. The
pursuit of such technologies leads to computational linguistics that reveals
the mechanism of languages and human intelligence. We have so far realized
trend analysis in accumulating social big data. We are now implementing ourchatbot on smart speakers for supporting healthcare of the elderly.
