Recognition of Genuine Polish Suicide Notes

چکیده
In this article we present the result of the research on the recognition of genuine Polish suicide notes (SNs). We provide useful method to distinguish between SNs and other types of discourse, including counterfeited SNs. The method uses a wide range of word-based and semantic features and it was evaluated using Polish Corpus of Suicide Notes, which contains 1244 genuine SNs, expanded with a manually prepared set of 334 counterfeited SNs and 2200 letter-like texts from the Internet. We utilised the algorithm to create the class-related sense dictionaries to improve the result of SNs classification. The obtained results show that there are fundamental differences between genuine SNs and counterfeited SNs. The applied method of the sense dictionary construction appeared to be the best way of improving the model.

Genuine and simulated suicide notes: An analysis of content.
The present study examined genuine and simulated suicide notes aiming to identify the measures of content that best differentiate between the two. Thirty-three genuine and thirty-three simulated suicide notes were content-analysed and data subjected to smallest space analysis (SSA), a Multidimensional Scaling Procedure. The core of all suicide notes was discovered to be constructed with the use...

متن کاملComment on Black's (1993) article, "comparing genuine and simulated suicide notes: a new perspective".
The recent article by Stephen T. Black (1993) comparing genuine suicide notes with simulated notes is examined here. This article corrected a sampling error made in the original study by E. S. Shneidman and N. Farberow (1957), but Black's design suffers from theoretical and methodological problems that render it uninterpretable: First, no theoretical background is elaborated, and no hypotheses ...
متن کاملSuicide Note Classification Using Natural Language Processing: A Content Analysis.
Suicide is the second leading cause of death among 25-34 year olds and the third leading cause of death among 15-25 year olds in the United States. In the Emergency Department, where suicidal patients often present, estimating the risk of repeated attempts is generally left to clinical judgment. This paper presents our second attempt to determine the role of computational algorithms in understa...
متن کاملStructure Annotation in the Polish Corpus of Suicide Notes
Polish Corpus of Suicide Notes (henceforth PCSN) is constructed to meet the needs of forensic linguistics. Suicide notes are messages created in borderline situation, shortly before death. Hence the annotation schema requires a complex description of a document structure, the textual content, as well as its linguistic properties. TEI was selected as the basis for the document encoding schema. T...
