Title: Design of a Prospective Search Engine for RSS Svilen Mihaylov University of Pennsylvania Abstract: RSS feeds are becoming increasingly popular way of delivering information with users ranging from personal blogs to news sites. A significant increase in the traffic generated by RSS feeds is projected. We focus our research on the importance of efficiently disseminate and distribute new web content to interested subscribers. In addition, as user demand increases, bottlenecks can occur at the sites of popular feeds. Our goal is to design a efficient system that can offload traffic from the publisher site and present a convenient and reliable dissemination service, while minimizing certain cost aspects such as number of machines and internet bandwidth. We also focus on providing ability for aggregation of relevant information in the case of clients connecting with mobile devices, as well as providing a classical retrospective search engine based on previously collected data.
