We evaluate the performance of our algo- rithm on multiple semantic relations ex- pressed using “verb”, “noun”, and “verb prep” lexico-syntactic patterns. ... use or effect of recursive patterns for differ- ent semantic relations. Therefore, going beyond (Kozareva et al., 2008; Hovy et al., 2009), we here introduce recursive patterns other than DAP that use ... eight lexico-syntactic patterns. Space prevents us from describing all of them, therefore we focus on the three most frequent patterns which capture a large diversity of semantic relations. The relative...
