What's In a Note: Construction of a Suicide Note Corpus

John P Pestian et al. Biomed Inform Insights. 2012.

Abstract

This paper reports on the results of an initiative to create and annotate a corpus of suicide notes that can be used for machine learning. Ultimately, the corpus included 1,278 notes that were written by someone who died by suicide. Each note was reviewed by at least three annotators who mapped words or sentences to a schema of emotions. This corpus has already been used for extensive scientific research.

Keywords: computational linguistics; corpus; natural language processing; suicide.
