Sentence:  The researchers found that the original texts spanned a variety of entropy values in different languages, reflecting differences in grammar and structure./ But strangely, the difference in entropy between the original, ordered text and the randomly scrambled text was constant across languages. This difference is a way to measure the amount of information encoded in word order, Montemurro says. The amount of information lost when they scrambled the text was about 3.5 <WSD>bits</WSD> per word. 
Meaning of the word marked with <WSD> tags:  A unit of measure for information entropy.
