Special issue of the Journal of Visual Languages and Computing
QUERYING MULTIPLE DATA SOURCES
1. Description of the topic
Information systems including query languages will in the near future allow
simultaneous querying of many data sources of heterogeneous type. Data sources may be
structured databases of any kind, semi-structured documents, as those found on the
web, sensors generating data such as images, sounds, time sequences of images (video
or IR), 3D documents, etc. Such information systems will then need to treat all the
different types of data in a seamless and unified ways, to retrieve data, to compose
and present the required information to the final user. A large number of applications
can easily be identified and the number is rapidly growing. Furthermore, existing
applications may be of both real and non-real time type.
2. The Motivation
The need for querying very large data volumes is evident. In querying system/languages
for heterogeneous multiple data sources many underlying problems need be solved at
the same time as new methods must be developed, e.g., for information fusion,
information filtering, transformation and integration of information, and handling of
uncertain information. To support these aspects of information querying new and more
powerful query languages must be developed to allow information extraction in various
ways, including result visualization in, for instance, virtual and augmented
realities, i.e. synthetic environments. The need for visualization of such
environments are and will be a consequence of the large number of visual data from
the many sources that must be dealt with. As a consequence, strong efforts are
required to identify and solve the problems that will occur in these environments,
since a large and growing number of the applications depend on successful developm!

3. Topics of interest for the special issue
Papers covering a fairly large number of topics are solicited. Topics of special
interest, but not necessarily limited to these aspects of querying multiple data
sources, are
- Data models
- Feature extraction querying
- Indexing techniques
- Knowledge based methods
- Knowledge fusion techniques
- Methods for information fusion in query languages
- Multi-source management systems
- Multimedia and sensor databases and database systems
- Qualitative spatial/temporal reasoning methods
- Query result presentation methods/techniques
- Visual query languages/systems
- World wide web (WWW) querying systems
The number of applications in the field is noticeably high and it is certain that the
number will be growing in the near future. Among the applications of interest for
this special issue on querying multiple data sources the following can be mentioned:
- Data mining
- Geographical information systems (GIS)/ Remote sensing/ Environmental monitoring and
protection
- Medical systems
- Multimedia/ Multisensor systems
- Systems for virtual realities/augmented realities/synthetic environments
4. Submission Info
Paper submitted should contain original materials not published in or submitted to
other journals. Six copies of the manuscript including the original (reproduction are
acceptable if they are clearly legible) and copies of all figures have to be submitted
to one of the Guest Editors. (In addition, an electronic version of the manuscript is
also accepted but only if in the pdf file format). One reproducible set of figures
(professionally drafted ink originals of line drawings and glossy prints of halftones)
will be required if the paper is accepted. Manuscript should be typewritten, double
spaced on one side of 8.5 in ( 11 in white paper with 1 inch margins. Page 1 should
contain the article title, author(s), affiliation(s), the name and the complete
address of the person to whom correspondence should be sent.
Any footnotes to the title (indicated by *, �, etc.) should be placed at the bottom of
page 1; Page 2 should contain a short abstract (100-150 words).
