Abstract.

 Textbook database examples are often wrong and simplistic. Unfortunately Data is never born
clean or pure. Errors, missing values, repeated entries, inconsistent instances and unsatisfied
business rules are the norm rather than the exception. Data cleaning (also known as data
cleansing, record linkage and many other terminologies) is growing as a major application
requirement and an interdisciplinary research area.
In this talk, we will start by discussing some of the major issues and challenges facing creating
effective and efficient data cleaning solutions. Then we will discuss some challenges and
criticize current conservative approaches to this very critical problem. Finally we will discuss
some of our work at QCRI in this area.
