Dear Prof. Greg Bolcer, University of California, Irvine:

I am aware of your professional interest in and research on
Internet-scale event notification.  Based on that, I thought the unique
Internet-scale real-time content-based publish-subscribe services of
PubSub Concepts would interest you.  There are several distinguishing
characteristics about PubSub Concepts, one of the most significant and
unique is that it is Internet scale.  It is also free to use and simple
to implement.  You can utilize it now.

If you would like to understand what makes PubSub different from all
others or you want an overview of the system, etc., go to
http://www.pubsub.com/news/.   If you want an even greater technical
understanding it or if you have any further ideas on collaboration
(e.g., extending the system across dimensions of mutual
interest, incorporating technology you'd like to see developed, etc.),
email me.

Please feel free to contact me if you or your colleagues have any

PubSub announces instant notification search capability for blogs and RSS

NEW YORK, NY - February 9, 2004 - PubSub Concepts (www.pubsub.com)
<http://www.pubsub.com)> today officially launched a no-cost
"search-and-alert" subscription service that continuously scans over a
million weblogs and RSS news feeds to instantly alert users whenever
specified items of interest appear. This unique, real-time, notification
service is made possible by PubSub's proprietary technology. Every day,
the company's servers perform billions of matches of requests against
newly published items.

PubSub's "search-and-alert" service is based on a new internet-scale
generation of Publish & Subscribe technologies designed to extend
traditional search engine capabilities, which currently function on
historic data. Today's search engines crawl the web to fill databases
and then wait for a user to come and search against that indexed
information. Because of the time it takes for search engines to crawl
and index billions of web pages, their information is, on average,
several weeks old. In addition, a user must repeatedly visit the search
engine to refresh their search.

Where search engines cover information from the past, PubSub's
"search-and-alert" service searches the future. The service receives a
user's search term only once, and then is continuously on alert as that
search term is matched in real-time across a vast array of weblogs and
RSS news feeds worldwide. Users are immediately notified whenever their
search term matches newly released information.

Users need not register personal information to take advantage of this
free service, which is actiivated once the user inputs a search phrase
and selects their notification preference. "Search-and-alert" then stays
active, continuously monitoring new content until the user commands

In addition to providing up-to-date information on search requests,
PubSub's service makes it possible to connect users interested in the
same subject matter. As users subscribe to alerts for real-time data on
a variety of interests, and the service responds by pointing to
information as it is published, people talking about the same topics
will immediately find each other. For instance, a search subscription
for "antique Porsche" will very quickly bring together all users who
have mentioned those words in their weblogs.

"Our technology creates connections between people based on what is
being said rather than where it is being published," said Bob Wyman,
PubSub's CTO and co-founder. "The technology, because it matches on
search terms, will rapidly find and connect users with the same interests."

In addition to "search-and-alert" results, PubSub's high-speed matching
technology allows developers to build applications that perform
statistical and trend analyses in real-time. The company has published
an API to the service, allowing users to be notified via REST the
instant their subscription is matched. Other interfaces such as SOAP
will be added soon.

To illustrate the capability of the service, PubSub has created sample
"search-and-alert" feeds that currently connect to news and conversation
on the Oscars, the U.S. Presidential Elections and Technology Trends. On
the site, users can very easily create their own customized
subscriptions to track published information on any item of interest,
including hobbies, favorite movies, interesting gadgets, favorite
celebrities, etc.
