Using comparable corpora to find new word translations is a promising approach for ex- tending bilingual dictionaries (semi-) auto- matically. The basic idea is based on the assumption that similar words have similar contexts across languages. The context of a word is often summarized by using the bag-of-words in the sentence, or by using the words which are in a certain dependency position, e.g. the predecessors and succes- sors. These different context positions are then combined into one context vector and compared across languages. However, previ- ous research makes the (implicit) assumption that these different context positions should be weighted as equally important. Furthermore, only the same context positions are compared with each other, for example the successor po- sition in Sp...
