Identifying Suicide Notes Using Forensic Linguistics
Abstract
Forensic linguistics is a subfield of corpus linguistics that uses linguistic information, analysis techniques, and linguistic insights to the setting of subjects such as law, criminal investigation, trial, and judicial procedure. In addition to different aspects of criminal investigation and court proceedings, its scope encompasses the domains of authorship identification (such as authorship verification, authorship profiling, and authorship attribution). The aim research is to identifying suicide notes using forensic linguistics. The research method used cumulative sum calculation strategy for elements: SL, Pron, Prep, Ver, Adj, Adv, Conj, CSS-SL, CSS-Pron, CSS-Prep, CSS-Ver, CSS-Adj, CSS-Adv, & CSS-Conj. The program read the given texts and counted the percentage of words that reflect different emotions, thinking styles, and social concerns. The result shows that from the two letters that have been analyzed above, it can be concluded that LETTER 1 has several aspects that support that the letter is original and was written by a single author. On the other hand, LETTER 2 does not have aspects that support the indicator that the letter is genuine, but all aspects analyzed strengthen the indicator that the letter is fabricated, as evidenced by the results of the analysis shown in the graph (file attached).
