A recent Wikipedia-based study by reference [10]
showed that query translations for cross-lingual IR can be
performed using only Wikipedia. An advantage of using
Wikipedia is that it allows translating phrases and proper
nouns well. It is also very scalable since it is easy to use the
most up to date version of Wikipedia which makes it able to
handle actual terms. The approach is that the queries are
mapped to Wikipedia concepts and the corresponding
translations of these concepts in the target language are used
to create the final query. The system build by the authors
called WikiTranslate is evaluated by searching with topics in
Dutch, French and Spanish in an English data collection.
