Call for Papers

International Workshop on
Data Mining for Information Mediation

in conjunction with the
9th International Conference on Database and Expert Systems Applications

DEXA'98
(http://www.ifs.tuwien.ac.at/dexa98/)
to be held in Vienna, August 24-28, 1998

1. Theme

Information mediation aims at the development of wrappers that
homogenize the access to heterogeneous sources, and mediators that
reconcile, merge, and abstract information from multiple sources. Data
mining provides efficient techniques for finding regularities and
irregularities in huge volumes of data.

These two fields depend heavily on each other. Information mediation
requires extensive knowledge about the inherent structure, semantics,
interdependencies, and inconsistencies in the data sources that cannot
be specified and maintained manually. On the other hand, specialized
algorithms for data mining make quite restrictive assumptions on the
analysed data set in terms of domain, structure, consistency, and
completeness, requiring typically extensive data cleaning in advance.

Applying data mining techniques for generating mediators and wrappers
thus bears the following challenges: How can one deal with
incomplete, noisy data which are only available at different
granularity? How can one obtain sufficient predictive quality with
only limited access to the underlying sources? How can background
knowledge in the form of domain-specific ontologies or user feedback
be used to guide the detection of regularities? How can different
mining techniques for various layers of wrapping and mediation be
combined?

This workshop aims at bringing together researchers on data mining and
on information mediation in order to come up with more scalable
solutions to information mediation. Particular topics of interest
include:

- source classification
- structure extraction
- wrapper generation
- (inter- and intra database) constraint learning
- concept learning
- schema summarization
- use and evolution of ontologies
- inconsistency detection & resolution

Both, papers on actual applications as well as on formal foundations are

strongly encouraged.

2. Submission Details

Authors are invited to submit research contributions representing
original, previously unpublished work. Submitted papers will be
carefully evaluated based on originality, significance, technical
soundness, and clarity of exposition. All papers will be refereed by at
least two members of the program committee. Accepted papers will be
published by IEEE Computer Society Press as proceedings of the DEXA'98
workshops, and if IEEE and authors agree, online. All submitted papers
must be formatted according to the author guidelines provided by IEEE
Computer Society Press, and must not exceed 5000 words. Guidelines for
the final paper can be found at
