The Sieve Online

The Sieve Online is an online service of the Sieve. The Sieve allows researchers to assess audience perception of classical or vernacular texts of various kinds. The Sieve uses a set of elementary textbooks as a benchmark to determine the vocabulary recognisable to an audience with a limited level of literacy. It can also be used to compare two texts. To use the tool, upload two texts or two sets of texts. The first text or set of texts will be used as a reference point to which the second text will be compared. The Sieve analyses both texts and differentiates shared and unique characters. It is also possible to look up any character using the dictionary tool (click on a character and the definition will pop up).
