So, they built translation system using bilingual dictionaries, then asked it to translate from English to Urdu, and then back to English, and minimized loss between original and double-translated English.
In one of my previous companies we used this technique to hire pair of translators: we gave translator pairs such task, and hired pair which reconstructed original text more closely.
- apendleton 8y agoNo, they didn't start with dictionaries, or any other parallel corpora; they learned the word by word translations as well from monolingual corpora, by finding alignments between monolingual word embeddings in the target languages.
