Claim One:
1. Method of extracting translations from translated texts, the method comprising the steps of: accessing a first text in a first language; accessing a second text in a second language, the second language being different from the first language, the second text being a translation of the first text; dividing the first text and the second text each into a plurality of textual elements; forming a sequence of pairs of text portions from said plurality of textual elements, each pair comprising a text portion of the first text and a text portion of the second text, each text portion comprising zero or more adjacent textual elements, each textual element of the first and the second text being comprised in a text portion of the sequence; calculating a pair score of each pair in the sequence using the number of occurrences of each of a plurality of features in the text portions of the respective pair and using a plurality of weights, each weight being assigned to one feature of said plurality of features; calculating an alignment score of the sequence using said pair scores, said alignment score indicating the translation quality of the sequence; and optimizing said alignment score by systematically searching through the space of alternatives and combining optimal alignments for subsequences into optimal alignments for longer sequences.
