OLAPing Uncertain Multidimensional Data Streams

The Faculty of Informatics is pleased to announce a seminar given by Alfredo Cuzzocrea

DATE: Thursday, December 5th, 2013
PLACE: USI Lugano Campus, room SI-013, Informatics Building (Via G. Buffi 13)
TIME: 15.30

Multidimensional data streams are playing a leading role in next-generation DSMS. This essentially because real-life data streams are inherently multidimensional, multi-level and multi-granular in nature, hence opening the door to a wide spectrum of applications ranging from environmental sensor networks to monitoring and tracking systems, and so forth. Consequently, there is a need for innovative models and algorithms for representing and processing such streams. Moreover, supporting OLAP analysis and mining tasks is a “first-class” issue in the major context of knowledge discovery from streams, for which above-mentioned models and algorithms are baseline components. This issue becomes more problematic when uncertain and imprecise multidimensional data streams are considered. Inspired by these critical research challenges, in this talk we will present an overview of major research issues in this context and an innovative technique for supporting OLAP over uncertain multidimensional data streams.


Alfredo Cuzzocrea is currently a Senior Researcher at the Institute of High Performance Computing and Networking of the Italian National Research Council, Italy, and an Adjunct Professor at the University of Calabria, Italy. His current research interests include multidimensional data modeling and querying, data stream modeling and querying, data warehousing and OLAP, OLAM, XML data management, Web information systems modeling and engineering, knowledge representation and management models and techniques, Grid and P2P computing, privacy and security of very large databases and OLAP data cubes, models and algorithms for managing uncertain and imprecise information and knowledge, models and algorithms for managing complex data on the Web, models and algorithms for high-performance distributed computing and architectures.

He serves as Area Editor for the Springer series "Communications in Computer and Information Science". He covers several roles in international journals, such as Editor-In-Chief, Associate Editor, Special Issue Editor (including JCSS, KAIS, IS, DKE). He edited about 20 books and conference proceedings. He is author or co-author of more than 270 papers in international conferences (including EDBT, SSDBM, MDM, DOLAP, DaWaK), international journals (including JCSS, KAIS, IS, DKE) and international books (mostly edited by Springer).
