A method is disclosed for translation of an input sentence in a source language to an output sentence in a target language using a store comprising a plurality of example sentences in the source language each paired with its translation in the target language. The method provides for improved matching of the input text against the store of example sentences by analysing both the sentences in the store and the input sentence using a bilingual resource combining aspects of a bilingual dictionary and thesaurus in order to determine the senses and translations of the words in the input sentence and the examples.
