Rather, contexts, circumstances, and lived experiences often shape views on abortion into more nuanced and complex perspectives. Qualitative data have also been shown to underpin belief systems regarding abortion. Social media, as a form of qualitative data, could reveal how attitudes toward abortion are communicated publicly in web-based spaces. Furthermore, in some cases, social media can also be leveraged to seek health information.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>This study applies natural language processing and social media mining to analyze Reddit (Reddit, Inc) forums specific to abortion, including r\/Abortion (the largest subreddit about abortion) and r\/AbortionDebate (a subreddit designed to discuss and debate worldviews on abortion). Our analytical pipeline intends to identify potential themes within the data and the affect from each post.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We applied a neural network\u2013based topic modeling pipeline (BERTopic) to uncover themes in the r\/Abortion (n=2151) and r\/AbortionDebate (n=2815) subreddits. After deriving the optimal number of topics per subreddit using an iterative coherence score calculation, we performed a sentiment analysis using the Valence Aware Dictionary and Sentiment Reasoner to assess positive, neutral, and negative affect and an emotion analysis using the Text2Emotion lexicon to identify potential emotionality per post. Differences in affect and emotion by subreddit were compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The iterative coherence score calculation revealed 10 topics for both r\/Abortion (coherence=0.42) and r\/AbortionDebate (coherence=0.35). Topics in the r\/Abortion subreddit primarily centered on information sharing or offering a source of social support; in contrast, topics in the r\/AbortionDebate subreddit centered on contextualizing shifting or evolving views on abortion across various ethical, moral, and legal domains. The average compound Valence Aware Dictionary and Sentiment Reasoner scores for the r\/Abortion and r\/AbortionDebate subreddits were 0.01 (SD 0.44) and \u22120.06 (SD 0.41), respectively. Emotionality scores were consistent across the r\/Abortion and r\/AbortionDebate subreddits; however, r\/Abortion had a marginally higher average fear score of 0.36 (SD 0.39).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our findings suggest that people posting on abortion forums on Reddit are willing to share their beliefs, which manifested in diverse ways, such as sharing abortion stories including how their worldview changed, which critiques the value of dichotomized abortion identity labels, and information seeking. Notably, the style of discourse varied significantly by subreddit. r\/Abortion was principally leveraged as an information and outreach source; r\/AbortionDebate largely centered on debating across various legal, ethical, and moral abortion domains. Collectively, our findings suggest that abortion remains an opaque yet politically charged issue for people and that social media can be leveraged to understand views and circumstances surrounding abortion.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2196\/47408","type":"journal-article","created":{"date-parts":[[2023,12,20]],"date-time":"2023-12-20T08:12:15Z","timestamp":1703059935000},"page":"e47408","source":"Crossref","is-referenced-by-count":26,"title":["Analyzing Reddit Forums Specific to Abortion That Yield Diverse Dialogues Pertaining to Medical Information Seeking and Personal Worldviews: Data Mining and Natural Language Processing Comparative Study"],"prefix":"10.2196","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2355-9881","authenticated-orcid":false,"given":"Danny","family":"Valdez","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1580-8697","authenticated-orcid":false,"given":"Lucrecia","family":"Mena-Mel\u00e9ndez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5509-5578","authenticated-orcid":false,"given":"Brandon L","family":"Crawford","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3894-5395","authenticated-orcid":false,"given":"Kristen N","family":"Jozkowski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2024,2,14]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1007\/s13178-018-0322-4"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1007\/s13178-019-00392-2"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1007\/s13178-020-00439-9"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.5993\/AJHB.45.1.7"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.ssresearch.2014.06.001"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1111\/ssqu.13157"},{"key":"ref7","unstructured":"SmithTWAn evaluation of Spanish questions on the 2006 general social surveyNORC\/University of Chicago200732024-01-29https:\/\/gss.norc.org\/Documents\/reports\/methodological-reports\/MR109%20An%20Evaluation%20of%20Spanish%\u200b20Questions%20on%20the%202006%20General%20Social%20Survey.pdf"},{"key":"ref8","unstructured":"BowmanKGoldsteinSAttitudes about abortion: a comprehensive review of polls from the 1970s to todayAmerican Enterprise Institute20211122022-07-21https:\/\/www.aei.org\/research-products\/report\/attitudes-about-abortion-a-\u200bcomprehensive-review-of-polls-from-the-1970s-to-today\/"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1177\/1532673x211053211"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1177\/106591290305600410"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1215\/03616878-10449896"},{"key":"ref12","unstructured":"FriedersdorfCThere are more than two sides to the abortion debateThe Atlantic202112102022-05-27https:\/\/www.theatlantic.com\/ideas\/archive\/2021\/12\/there-are-more-than-two-sides-to-the-abortion-debate\/620978\/"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1093\/ooec\/odad051"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.4337\/9781788979467.00008"},{"key":"ref15","unstructured":"PerrinASocial media usage: 2005-2015Pew Research Center20151082024-01-29https:\/\/www.pewresearch.org\/internet\/2015\/10\/08\/social-networking-usage-2005-2015\/"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0254114"},{"key":"ref17","doi-asserted-by":"crossref","DOI":"10.1017\/CBO9781139088510","author":"Zafarani, R","year":"2014","journal-title":"Social Media Mining: An Introduction"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1363\/psrh.12225"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1016\/j.osnem.2018.11.001"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1097\/01.AOG.0000826104.75828.4f"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pdig.0000143"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1177\/0044118x221129642"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1891\/0886-6708.vv-d-18-00148"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1007\/s10461-023-04134-9"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph18179013"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2021.05.011"},{"key":"ref27","doi-asserted-by":"publisher","DOI":"10.1016\/j.contraception.2020.07.047"},{"key":"ref28","doi-asserted-by":"publisher","DOI":"10.3390\/a16090424"},{"key":"ref29","doi-asserted-by":"publisher","DOI":"10.1016\/j.socscimed.2023.115978"},{"key":"ref30","author":"Richards, NK","year":"2024","journal-title":"Research Square.
