The Data Analytics group at QCRI has built expertise focused on three core data management challenges that will enable the effective use of this growing asset class: extraction from its natural digital habitat, integration from a large and evolving number of sources, and robust cleaning processes to assure data quality and validation.
The Data Trio: Extraction, Integration, and Cleaning: Institutions and industries at a national level deal with large scale, heterogeneous data collected from large number of sources. The main challenge is a judicious use of the information within and across organizations to make informed decisions and to run operations effectively.
At QCRI, we are focusing on the interaction among three core data management challenges that will enable effective use of the continuously growing data: Information Extraction, Data and Schema Integration, and Data Cleaning.
Going beyond traditional ETL approaches, we are investigating multiple new directions, including: handling unstructured data; interleaving extraction, integration, and cleansing tasks in a more dynamic and interactive process that responds to evolving data sets and real-time decision-making constraints; and leveraging the power of human cycles to solve hard problems such as data cleaning and information integration.
Scalable Knowledge Models: Grand challenges mean big data. ‘Knowledge base’ is the term commonly used to refer to data, along with the rules and the logic that describe the information within this data. Large-scale knowledge management is a core-computing challenge due to the expensive process involved in reasoning about the data and inferring the facts and the various semantics embedded within. We focus on developing efficient knowledge representation models and semantic-aware query languages and processing engines that bring semantics to real applications. Main applications domains include media and health, where current approaches are either too expensive or fall short in delivering user needs.
QCRI provides a unique opportunity to be a part of building a high-impact research center in a geographical area that can have long-term effects in terms of transforming Qatar and the region as a whole. It’s this long-term vision and related investments from Qatari leadership that I find so exciting and believe will forever change the future of the people of the Middle East for the better.
To be part of something different than what I had been used to at Purdue University and contribute to the first computing research institution in the region.
QCRI is at an exciting stage of growth with world-class researchers. I am excited about the opportunity to establish QCRI at the forefront of data mining research.
Storing, managing, retrieving, and mining Big Data is one of the most difficult computing challenges of our times. Along with my colleagues in the Data Analytics Group at QCRI, I am interested in enabling end-users to utilize large datasets to the fullest by designing infrastructure and algorithms, and applying data and text mining techniques.
QCRI provides an ideal environment to conduct high-impact research which can transcend disciplinary boundaries.
