ROSES : Really Open, Simple and Efficient Syndication

Team : BD

Social web portals (Twitter, Facebook), web blogs, online journals etc. produce continuous streams of text items (news, messages). User subscriptions to these streams can be modeled as queries which are continuously filtering and ranking new information items. A major challenge is then to efficiently process millions of such subscription queries. Initiated by the ROSES ANR project ROSES (2008-2012) on RSS feed aggregation and filtering we worked in on multi-query optimisation~(PhD J. Creus), on efficient refresh strategies for dynamic RSS feeds (PhD R. Horincar), and on continuous top-k query processing (PhD of N. Vouzoukidou ).
