In this proposal, we introduce a scalable distributed publish/subscribe system for selective information dissemination. We propose two models A-ToPSS and G-ToPSS for two different matching problems: approximate matching and semantic matching. A-ToPSS aims at processing uncertainty information, while G-ToPSS aims at filtering graph-based metadata. We describe problems left in these two models an...

To help users cope with information overload, Selective Dissemination of Information (SDI) will increasingly become an important tool in wide area information systems. In an SDI service, users post their long term queries, called pro les, at some SDI servers and continuously receive new, ltered documents. To scale up with the volume of information and the size of user population, we need a dist...
