There are essentially two ways to assess the readability of a text. "Global"
approaches seek to evaluate a text as a whole. ("Readability formulas" are perhaps the most
common variety of global assessment.) "Local" approaches, however, look inside the
text at the specific vocabulary or syntactic structures that make reading a challenge.
At TText, we prefer to look at the "texture" of a text, because this information is
most useful for writers, educators, and researchers who want to understand how and
why a particular text is readable, or not. We see the
"TopoText" software development project
as one way to help writers improve the readability of their texts without resorting to readability
formulas.
