my earlier post has 33 views and no replies?

this is google books

our interest here is in authorship attribution, questioned document examination etc.

Is there a basis to say that the questioned document, the RN, is a match to known exemplars, both requested and historical

I do NOT have journal access but this journal summarizes Daubert and forensic linguistics

journal of applied linguistics

Recent work has taken different approaches in attempting to use linguistics to identify the authors of documents by the style of their writing. Traditionally, linguists have sought to identify similarities and differences in a host of features, including spelling, syntax, word usage and others, and to draw inferences regarding authorship based on a comparison of those features. However, developments in the law of evidence in the United States during the past ten years have focused the attention of courts on the validity and reliability of a technique before an expert will be permitted to offer an opinion based upon it. Courts are especially mindful of whether a technique can identify an error rate with sufficient reliability. In this context, it is incumbent on the field to respond with methods that will be acceptable to courts. This paper discusses some significant achievements being made in meeting this challenge, including efforts to identify syntactic features that are diagnostic of authorship, eclectic methods that look for constellations of similarities, and the use of linguistic corpora, a development in which Malcolm Coulthard played a pioneering role.

here are some additional resources

click or copy and paste - i use firefox and i use foxit pdf editor

i use windoze and when i click it on firefox, a window pops up to d/l the pdf

this journal article which i do not have access to is an example of validating forensic linguistics in form of questioned document examination

n this work we discuss author identification for documents written in Portuguese. Two different approaches were compared. The first is the writer-independent model which reduces the pattern recognition problem to a single model and two classes, hence, makes it possible to build robust system even when few genuine samples per writer are available. The second is the personal model, which very often performs better but needs a bigger number of samples per writer. We also introduce a stylometric feature set based on the conjunctions and adverbs of the Portuguese language. Experiments on a database composed of short articles from 30 different authors and Support Vector Machine (SVM) as classifier demonstrate that the proposed strategy can produced results comparable to the literature.

compare with Cherokee's "forensic linguistics"

I believe that one reason for using various phrases and references to movies with recognizable kidnapping/faction/true crime themes is to thwart any attempt to develop a picture of the writer through stylistic analysis (that and to make it obvious - after initially triggering FBI involvement - that the RN was bogus, thereby suggesting it was part of an elaborate staging). We are not really studying two serious works of literature or communication here. It is extraordinary to think, as many do, that an emotionally distraught man and woman caught up in the throws of covering up the accidental death of their child, as they propose, could write such a ridiculously long and silly ransom note. On the other hand, I think we can make some observations about what kind of a person might go to the trouble of writing a note like this and what were they trying to achieve. That is the value of studying the RN.
