We collected lexicons for fine-grained categories of SS and SI using an iterative method that included manual chart reviews and semi-automatic methods.

3.1.1 Manual Chart ReviewZhu et al.

[26] developed a lexicon for identifying SI from clinical notes of patients with prostate cancer in the context of recovery support. Initially, this lexicon, which included 24 terms, was selected; however, it yielded relatively fewer clinical notes at MSHS and WCM compared to the published report. A list of terms for each category was created and extensively reviewed by the study team which included clinical psychiatrists and psychologists.

We manually reviewed 50 notes at each site to find SS and SI keywords to enrich the existing lexicons.3.1.

2 Semi-automatic MethodThe lexicons from manual chart review as above were enhanced using word embeddings. First, the manually generated lexicons were vectorized using word2vec [39] and Equation 1. :::infoThis paper is available on arxiv under CC BY 4.
