PubSub reads over 6.4 million weblogs, more than 50,000 internet newsgroups and all SEC (EDGAR) filings.
PubSub is a matching service that instantly notifies you when new content is created that matches your subscription. Using a proprietary Matching Engine, PubSub is able to read millions of data sources on your behalf and notify you instantly whenever a match is made.
The heart of the PubSub service is a powerful, proprietary Matching Engine that makes it possible, for the first time, to match millions of search queries against thousands of new pieces of information every second.
Traditional search stores data and then allows you to find documents within that store of data. PubSub operates by first storing your subscription query, and then watching for new information that matches it. Your query will be checked against every piece of new information passing through our Matching Engine.
The PubSub service is compatible with any information delivery system that can be accessed from the Internet – including email, SMS, PDA/mobile devices and Instant Messaging networks – allowing you to select where, when, and how you want to receive your information.
How Does PubSub Work?
For all alerting and notification systems, the fundamental problem is “Matching”. Matching is the exercise of reconciling new information events against stored queries. Matching has always been extremely difficult on the internet, where millions of information events are happening every second.
PubSub’s core technology is a Matching Engine that matches new information events against stored queries at more than three billion matches per second! This capability allows the PubSub service to constantly monitor millions of information events on your behalf.
The PubSub service works by finding content on the internet, passing it through the Matching Engine and alerting you whenever a match is made. Content is organized into “Topics” like Weblogs or SEC filings. We started with three topics, but we’ll be adding many more in the coming months.
