Are there any tools which allow to measure the range of vocabulary in the text? If you know about such, please, provide their names, links, etc.
My aim is to find more varied in terms of range of vocabulary reading, so I will be able to increase lexical variety of my own speaking.
I've opened separate question to find out if such kind of rating already exists for modern Ukrainian literature and translations. Any rating by the vocabulary richness for modern Ukrainian literature works (or authors)?
UPD: I've searched a bit for more suitable term and found that "Vocabulary richness" describes better what I'm asking about.
