Continual Queries: Intelligent Access to Fresh Information
ŠT—v
Browsing (pull) has been the dominant mode of access to Web
information, aided by search engines such as Google and referral
services such as Yahoo. However, as more dynamic information becomes
available, the labor intensive nature of browsing makes it less
attractive. In contrast, the push mode of information delivery has
failed due to the excessive amount of data that easily overwhelms the
users. We have been working on the concept and implementation of
Continual Queries to automate the process of creating intelligent
information delivery services that brings timely new information of
relevance to users. This talk summarizes the progress made in the CQ
project, including the related component technologies of wrapper
generation and automated object recognition in web pages. The CQ
system is running as a service available over the Internet.
