Title
Semantische Eingrenzung im Freitext-Retrieval auf der Basis morphologischer Segmentierungen

Abstract
The basic problem in freetext retrieval is that the retrieval language is not properly adapted to that of the author. Morphological segmentation, where words with the same root are grouped together in the inverted file, is a good eliminator of noise and information loss, providing high recall but low precision
