Application ID: 13585266

Base Claim:
1. A method for creating or updating parallel corpus in a machine translation system, comprising the steps of: without parallel corpus, translating a test set E from a first collection to a second collection so as to create a set F in the second collection, and translating the set F from the second collection to the first collection so as to create a set E′ in the first collection, wherein differences between E and E′ are determined; computing confidence scores for a translation of each item in the test set E based on a similarity of E and E′; and based on the confidence scores, adding translations to the parallel corpus, wherein the parallel corpus is stored in memory on the machine translation system.

Claim 5:
5. The method of claim 1 , further comprising preparing the test set E to be updated by: translating a test set G using an existing parallel corpus; calculating a translation accuracy score for one or more items in the test set G; comparing the translation accuracy score for each item to a desired performance score to determine whether the parallel corpus needs to be updated for that item; and if the translation accuracy score for an item is equal to or greater than a desired performance score, removing that item from the test set G, so as to create the test set E.
