Abstract: In this paper we propose a novel approach that combines syntactic and context information to identify lexical semantic relationships. We compiled semi-automatically and manually created training data and a test set for evaluation with the first sentences fromthe German version ofWikipedia. We trained the Trigrams’n’Tags Tagger by Brants (Brants, 2000) with a semantically enhanced tagset. The experiments showed that the cleanliness of the data is far more important than the amount of the same. Furthermore, it was shown that bootstrapping is a viable approach to ameliorate the results. Our approach outperformed the competitive lexico-syntactic patterns by 7% leading to an F1-measure of .91.
