The RuleML Webinars feature rule topics of shared interest to the RuleML community. Each Webinar currently consists of a 30-minute presentation interleaved with / followed by about 10 minutes of discussion. Presenters provide their slides (PDFized as exemplified in the Title column below) prior to the Skype-based Webinars (using "Share Screens"). The events typically happen on the last Friday of the month at 9 AM Pacific / 12 Noon Eastern / 6 PM Central Europe. Discussions sometimes continue in the RuleML Telecons immediately after the Webinars -- and have led to constructive feedback, new connections, and off-line follow-up. Prospective presenters should contact Harold Boley.
