project description

Transfer of IR-techniques to the world of semi-structured data (XML) is an ongoing issue. Although there are many ideas about how to do IR on trees, these focus on improving IR quality, not on optimizations for speed or memory consumption.

Can IR techniques be integrated into existing XML-DBMSs?

IR-systems developed stand-alone in general do not profit from available high performance DBMSs. Currently I focus on injecting the Score Region Algebra IR technology, introduced by the CIRQUID Project (from Twente University, EWI Database Group), into the Pathfinder XQuery compiler (developed at TU München, Lehrstuhl für Datenbanksysteme).

Future issues of this research project are:
