Then we present in sections 4 and 5 a com- parative evaluation experiment proving that a hy- brid approach leads to more accurate results than a classical approach ... with parsing. Its author had to simulate parsing because of the lack, at the time, of parsing tools for Ger- man. Our report, that concerns an actual system and a large data set, v...
