 The test data contain 1 reference translation per sentence. The test data contain 1 reference translation per sentence.

 +Our preprocessing of the data included the following steps:
 +
 +  * Further tokenization. Although Tides in the form we got it is roughly tokenized, there were tokens (like "anglo-american") we wished to split into smaller tokens.
 +  * Unicode normalization. E.g., devanagari "z" was rewritten as "j"+"nukta".
 +  * Cleaning. Sometimes a part of a sentence was removed but never a whole sentence, so the number of sentences is still the same.
 +
 +We are planning on making all the cleaning scripts available here. After preprocessing, the size of Tides changed as follows:
 +
 +| **Part** | **Sentences** | **Tokens en** | **Bytes en** | **Tokens hi** | **Bytes hi** |
 +| train |  50,000 |  1,226,144 |  6,499,532 |  1,312,435 |  15,648,541 |
 +| dev |  1,000 |  22,485 |  118,242 |  24,363 |  288,062 |
