Many people are turning to social networks such as Facebook, WhatsApp, Twitter, etc., to express their opinions and feelings regarding Long COVID. In this paper, we analyse text messages in the Greek language posted on the Twitter platform in 2022 to extract popular discussion topics and classify the sentiment of Greek citizens regarding Long COVID. Results highlighted the following discussion topics: Greek-speaking users discuss Long COVID effects and time required to heal, Long COVID effects in specific population groups like children and COVID-19 vaccines. 59% of analysed tweets conveyed a negative sentiment while the rest had positive or neutral sentiment. The analysis shows that public bodies could benefit from systematically mining knowledge from social media to understand public\u2019s perception of a new disease and take action.<\/jats:p>","DOI":"10.3233\/shti230554","type":"book-chapter","created":{"date-parts":[[2023,6,30]],"date-time":"2023-06-30T07:54:24Z","timestamp":1688111664000},"source":"Crossref","is-referenced-by-count":3,"title":["Mining Greek Tweets on Long COVID Using Sentiment Analysis and Topic Modeling"],"prefix":"10.3233","author":[{"given":"Afroditi","family":"Katika","sequence":"first","affiliation":[{"name":"Faculty of Nursing, National and Kapodistrian University of Athens, Athens, Greece"},{"name":"Department of Digital Systems, School of Information and Communication Technologies, University of Piraeus, Piraeus, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emmanouil","family":"Zoulias","sequence":"additional","affiliation":[{"name":"Faculty of Nursing, National and Kapodistrian University of Athens, Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vassiliki","family":"Koufi","sequence":"additional","affiliation":[{"name":"Department of Digital Systems, School of Information and Communication Technologies, University of Piraeus, Piraeus, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Flora","family":"Malamateniou","sequence":"additional","affiliation":[{"name":"Faculty of Nursing, National and Kapodistrian University of Athens, Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","Healthcare Transformation with Informatics and Artificial Intelligence"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SHTI230554","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,6,30]],"date-time":"2023-06-30T07:54:26Z","timestamp":1688111666000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SHTI230554"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,6,29]]},"ISBN":["9781643684000","9781643684017"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/shti230554","relation":{},"ISSN":["0926-9630","1879-8365"],"issn-type":[{"value":"0926-9630","type":"print"},{"value":"1879-8365","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,6,29]]}}}
