A comparative study of likelihood ratio based forensic text comparison procedures: Multivariate kernel density with lexical features vs. word N-grams vs. character N-grams

Ishihara, Shunichi


This is a comparative study to empirically investigate the performances of three different procedures for calculating authorship attribution likelihood ratios (LR). The procedures to be compared are: 1) a procedure based on multivariate kernel density (MVKD) with lexical features; 2) a procedure based on word N-grams; and 3) a procedure based on character N-grams. Furthermore, the best-performing LRs of these three procedures are fused into combined single LRs using a logistic-regression...[Show more]
