The problem of poor data quality stored in database-backed information systems
is widespread in the governmental, commercial and industrial environments.
Alarming situations with various information quality problems can not be
ignored anymore and theoretical as well as pragmatic approaches are urgently
needed to be proposed and validated. As a consequence, information quality is
now becoming one of the hot topics of emerging interest in the academic and
industrial communities.
Many processes and applications (such as information system integration,
information retrieval, and knowledge discovery from databases) require various
forms of data preparation or repair with several data processing techniques,
because the data input to the application-dedicated algorithms is assumed to
conform to nice data distributions, containing no missing, inconsistent or
incorrect values. This leaves a large gap between the available
“dirty” data and the available machinery to process the data for
application purposes.
The second edition of the International Workshop IQIS 2005 (Information
Quality in Information Systems) in conjunction with SIGMOD'2005 in Baltimore focuses on
database-centric issues in data quality (scalability, quality-aware query
processing, applications like data integration). It intends to address methods, techniques of massive data processing
and analysis, methodologies, new algorithmic approaches or frameworks for
designing data quality metrics in order to understand and to explore data
quality, to find data glitches (as data quality problems such as duplicates,
errors, outliers, contradictions, inconsistencies, etc.) and to ensure both
data and information quality of database-backed information systems.
We invite the
submission of original research contributions, industrial papers and case
studies relating to all aspects of data quality and information quality defined
broadly, all along the data life cycle from creation to usage and also through
the data preparation, cleaning and analysis processes.
The duration of the workshop
is one day dedicated to scientific and technical presentations matching the following topics of interests.
