The health and safety of incarcerated persons and correctional personnel have been prominent in the U.S.news media discourse during the COVID-19 pandemic.
Examining changing attitudes toward the health of the incarcerated population is imperative to better assess the extent to which the general public favors criminal justice reform.However, existing natural language processing lexicons that underlie current sentiment analysis (SA) algorithms may not perform adequately on news articles related to criminal justice due to contextual complexities.News discourse during the pandemic has highlighted the need for a novel SA lexicon and algorithm (i.
e., an SA package) tailored for examining public health policy in the context of the criminal justice system.We analyzed the performance of existing SA packages on a corpus of news articles at the intersection of COVID-19 and criminal justice collected from state-level outlets between January and May 2020.
Our results popularfilm.blog demonstrated that sentence sentiment scores provided by three popular SA packages can differ considerably from manually-curated ratings.This dissimilarity was especially pronounced when the text was more polarized, whether negatively or positively.A randomly selected set of 1,000 manually scored sentences, and the corresponding binary document term matrices, were used to train two new sentiment prediction algorithms (i.
e., linear regression and random forest regression) to verify the performance of the manually-curated ratings.By better accounting for the unique context in which incarceration-related terminologies are used in news media, both of our proposed models outperformed all existing SA packages considered for comparison.
Our findings suggest that there is a need to develop a novel lexicon, and potentially an accompanying algorithm, for analysis of text related to public health within the criminal justice system, as well as criminal justice more broadly.Author summary Incarceration is a social cause of disease, with currently and formerly incarcerated individuals being more likely to face vulnerabilities to disease outbreaks.The COVID-19 pandemic amplified the health-related shortcomings in the U.
S.prison system, prompting the U.S.
Department of Justice to consider reforming early release and home confinement measures.Public attention and news media coverage has concurrently increased, with particular attention to criminal justice reform initiatives and systemic ethnoracial inequities.Here, we attempted to characterize public sentiment towards criminal justice reform, in light of the pandemic and public health concerns, using existing tools to assessing positive, negative, and neutral sentiment.
Our findings suggest these existing tools are inadequate for accurately gauging sentiment in texts at the intersection of public health and criminal justice, but also for potentially for texts related to criminal justice more broadly.Along with other opheliasmuse.com approaches, properly validated tools for understanding sentiment can assist in gauging the scope of public health and reform measures for incarcerated persons and public support for or against criminal justice reform.
