Authorship Attribution: What's Easy and What's Hard?
We consider variants of authorship attribution problems, ranging
from the reasonably easy to the unreasonably difficult, pointing out the
conditions under which each is solvable. We begin with vanilla attribution
problems in which an anonymous document needs to be attributed to one of a
small closed set of candidate authors for each of whom we have copious
training data. More difficult cases include ones in which the candidate set
might be extremely large (possibly in the tens of thousands) or in which
the true author might not be in the candidate set at all or for which we
have very little training data. Finally (if time permits), we consider
multi-author documents which we need to decompose into distinct authorial
threads without being provided with any training data at all. Some
applications to the Hebrew Bible can be discussed, if there is interest.
