If two chunks of text have a relatively high degree of similarity then their combined compressed length will be less than for two equivalent but dissimilar chunks. So, in the case of authorship, if you have text from 3 known authors and one unknown author you combine the unknown one with each of the known ones and compare the zipped length of these combined text to the zipped length of the 3 individual texts. The combined text that has the smallest increase in length relative to the individual length of its know text is then most likely to have both texts authored by the same person (I hope that makes sense).
