 You can access UDHR (Universal Declaration of Human Rights) [here](http://www.unicode.org/udhr/d/), but when a verse is missing, they have texts such as "missing" or "?". Also, about 1/3 of the sentences consist only of "articles 1-30" in different languages. We cleaned the entire dataset from XML files and selected only the paragraphs. We cleared any unrelated language texts from the data and also removed the cases that were incorrect.
 
-Incorrect? Look at the ckb and kmr files in the UDHR. Both are the same! ckb is known for the Arabic script, although it can also be written in Latin. Clearly, a unique file cannot belong to two different languages for our task. We also deleted files that we believe those scripts are no longer in use.
+Incorrect? Look at the ckb and kmr files in the UDHR. Both are the same! ckb is known for the Arabic script, although it can also be written in Latin. Clearly, a unique file cannot belong to two different languages (at least in the text language identification task). We also deleted files that we believe those scripts are no longer in use.
 
 The deleted files include:
 - ckb_Latn (Arabic is in use.)
