We collected a text corpus, consisting of 3,622 Facebook posts containing more than seven words from 151 public libraries. We conducted a term frequency analysis and latent dirichlet allocation (LDA) topic modeling to explore the content of Facebook posts. The results revealed that terms related to library programming and library event announcements appeared frequently. The LDA topic modeling identified 25 topics underlying the corpus. We observed various topics were posted on public library Facebook Pages while library programming and event related topics were most common.<\/jats:p>","DOI":"10.1002\/pra2.2017.14505401129","type":"journal-article","created":{"date-parts":[[2017,10,24]],"date-time":"2017-10-24T03:35:36Z","timestamp":1508816136000},"page":"718-719","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Content analysis of facebook posts in public libraries based on textual analysis"],"prefix":"10.1002","volume":"54","author":[{"given":"Soohyung","family":"Joo","sequence":"first","affiliation":[{"name":"University of Kentucky  USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kun","family":"Lu","sequence":"additional","affiliation":[{"name":"University of Oklahoma  USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,10,24]]},"reference":[{"issue":"2","key":"e_1_2_5_2_1","article-title":"Social networking sites as marketing and outreach tools of library and information services","volume":"13","author":"AlKindi S.
