We present a method which, given a few words defining a concept in some lan- guage, retrieves, disambiguates and ex- tends corresponding terms that define a similar concept in another specified lan- guage. This can be very useful for cross-lingual information retrieval and the preparation of multi-lingual lexical re- sources. We automatically obtain term translations from multilingual dictionaries and disambiguate them using web counts. We then retrieve web snippets with co- occurring translations, and discover ad- ditional concept terms from these snip- pets. Our term discovery is based on co- appearance of similar words in symmetric patterns. We evaluate our method on a set of language pairs involving 45 languages, including combinations of very dissimilar ones such as Russian, Chinese, ...
