Is there a method to calculate something like general \"similarity score\" of a string? In a way that I am not comparing two strings together but rather I get some number (h
It is unlikely one can get a rather small number from two phrases that, being compared, provide a relevant indication of the similarity of their initial phrases.
A reason is that the number gives an indication in one dimension, while phrases are evolving in two dimensions, length and intensity.
The number could evolve as well in length as in intensity but I'm not sure it'll help a lot.
In two dimensions, you better look at a matrix, which some properties like the determinant (a kind of derivative of the matrix) could give a rough idea of the phrase trend.
