Word Alignment
A common use of aligned texts is the derivation of bilingual dictionaries and terminology databases.
This is usually done in two steps: First, the text alignment is extended to a word alignment. Then, some criterion, such as frequency is used to select aligned pairs for which there is enough evidence to include them in the bilingual dictionary.
Using a ?2 measure works well unless one word in L1 occurs with more than one word in L2. Then, it is useful to assume a one-to-one correspondence.
Future work is likely to use existing bilingual dictionaries.
