[9] While teaching linguistics at North Carolina State University (1990–1994), Carole Chaski was asked by police to examine several versions of an alleged suicide note found on a home computer.
"[14] Chaski's methodology, according to Olsson, includes software that uses four grammar rules to identify a text's syntactic markedness, in combination with measurements of the ways punctuation is used by a writer.
"[14] Chaski is known for her research on the reliability of different variables, such as spelling and syntax, in forensic linguists' analysis of discriminants amongst unknown authors.
"[12] Ben Zimmer of The New York Times wrote that Chaski was also working on the problem of "identifying the authorship of a document that was produced by a computer to which multiple users had access" by developing software that could categorize the linguistic structures which tend to be stable across different styles of writing.
[11] As of 2016, Chaski served on the editorial board of Brief Chronicles, a peer reviewed journal of Shakespearean authorship studies that is no longer in production.
[21] Additionally, she is a part of ALIAS Technology's "Linguist Support Team for SynAID, Profiler and other modules as cases warrant.
