An apparatus, method, and a computer program product are provided for improving the translation quality of text when a text sequence, such as a sentence, includes a parenthetical part delimited by a separator or separators, such as parentheses, quotation marks, or the like. The apparatus applies an algorithm which is configured for using several methodologies in sequence to identify an optimum position for insertion of the translated parenthetical in the main part of the translated text sequence. As a result, the translated parenthetical is more likely to be correctly delimited by separators and more likely to be correctly placed in the main part than in a conventional translation system which automatically translates each sentence as a whole.
