Integration of Web Information Sources by Mobile Users
Short Description of Project
Recently, the number of Web sites providing location-dependent
information is continuously growing, and mobile users can query these
Web contents through their hand-held devices. Typically, such users
want to find useful information quickly according to their
locations. To do so, information from these Web sites should be
integrated together as a new simpler information source. However,
because there are many various Web sites, preparing all possible
integrations by a system designer would be expensive. A better
solution is to let mobile users define necessary integration by
themselves according to their purposes and locations. This requires
that
- the integration of Web information sources must be
defined (as a database view definition) by individual users on
their PDAs even when the PDAs are network-disconnected; and
- the definitions must be materialized later by system-side
servers when network connection is set up.
This work proposes a system architecture for the above usage.
Firstly, to realize easy integration on PDAs, a new integration style
called navigational integration of Web information sources
is proposed. Thereafter a necessary wrapper/mediation architecture for
materializeing the navigational integration is proposed.
