Talk Announcement

Evaluation of XPath Queries against XML Streams using SPEX

Speaker: Dan Olteanu

Abstract: This talk presents the main design ideas and properties of the streamed and progressive evaluation strategy of forward XPath queries against XML streams called SPEX. SPEX (1) is specified using compositions of so-called stream processing functions, (2) is implemented efficiently using networks of deterministic pushdown transducers, and (3) has polynomial combined complexity.


Time and location: At the seminar "Querying and Storing XML" , Saarland University.
May 3rd, 4.15 p.m. (punctual/s.t.) in lecture hall 001 (building 45).
