ZigZag Uses Amzi! and Lotus to Help You Find Anything on the Internet
ZigZag has built Ziggy the Navigator to help Web users find and use the
best Internet search services for the particular type of media they are
seeking. Ziggy supports finding people, companies, pictures, sounds, and
usenet. Their mission is to greatly reduce the amount of time people spend
searching Internet by recommending only the most appropriate search services
and directories of information, and by presenting all those tools on a single
The heart of the system is Lotus' Domino Web server with a comprehensive
Lotus Notes database of the many Internet searching services and directories
of information. For each service or directory, this database describes
what things it is good at looking for, how to interface with it, and the
formats of the resulting output.
ZigZag has developed a clever LotusScript and Amzi! Prolog program that
analyzes Notes databases to generate WebLS rules. Notes provides the hierarchical
structure, and Prolog reasons over the database and assists in the construction
of the WebLS rules, regardless of the database format.
The WebLS rules comprise the intelligent user interface (appropriately
called "Ziggy Express") that asks Web searchers what they are looking
for via Web forms. The rules match your needs (entered in the forms) and
then display only the search services that are the most appropriate. This
intelligent interface is dynamically generated anytime the underlying
Notes database is updated, thereby providing the most up-to-date information
in real time.
ZigZag is working on a generalisation of this scheme which will enable
web users to create and maintain Lotus Notes Databases from which WebLS
knowledge bases can be automatically generated.
