Meta Analysis within Authorship Verification

In an authorship verification problem one is given writing examples from an author A, and one is asked to determine whether or not each text in fact was written by A. In a more general form of the authorship verification problem one is given a single document d only, and the question is whether or not d contains sections from other authors. The heart of authorship verification is the quantization of an author's writing style along with an outlier analysis to identify anomalies. Human readers are well-versed in detecting such spurious sections since they combine a highlydeveloped sense for wording with context-dependent meta knowledge in their analysis. The intention of this paper is to compile an overview of the algorithmic building blocks for authorship verification. In particular, we introduce authorship verification problems as decision problems, discuss possibilities for the use of meta knowledge, and apply meta analysis to postprocess unreliable style analysis results.
