This study presents an unsupervised algorithm designed to extract body-text leveraging large volume of data. Using DBSCAN clustering over aggregate pages, our method extracts and organize text blocks using their content and coordinates. Evaluation results demonstrate precision scores ranging from 0.82 to 0.98, recall scores from 0.62 to 0.94, and F1-scores from 0.71 to 0.96 across various medical specialty sources. Future work includes dynamic parameter adjustments for improved accuracy and using larger datasets.<\/jats:p>","DOI":"10.3233\/shti240382","type":"book-chapter","created":{"date-parts":[[2024,8,23]],"date-time":"2024-08-23T08:46:22Z","timestamp":1724402782000},"source":"Crossref","is-referenced-by-count":0,"title":["Unsupervised Extraction of Body-Text from Clinical PDF Documents"],"prefix":"10.3233","author":[{"given":"Adel","family":"Bensahla","sequence":"first","affiliation":[{"name":"Division of Medical Information Sciences, Geneva University Hospitals, Switzerland"},{"name":"Department of Radiology and Medical Informatics, University of Geneva, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jamil","family":"Zaghir","sequence":"additional","affiliation":[{"name":"Division of Medical Information Sciences, Geneva University Hospitals, Switzerland"},{"name":"Department of Radiology and Medical Informatics, University of Geneva, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christophe","family":"Gaudet-Blavignac","sequence":"additional","affiliation":[{"name":"Division of Medical Information Sciences, Geneva University Hospitals, Switzerland"},{"name":"Department of Radiology and Medical Informatics, University of Geneva, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"Lovis","sequence":"additional","affiliation":[{"name":"Division of Medical Information Sciences, Geneva University Hospitals, Switzerland"},{"name":"Department of Radiology and Medical Informatics, University of Geneva, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","Digital Health and Informatics Innovations for Sustainable Health Care Systems"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SHTI240382","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,8,23]],"date-time":"2024-08-23T08:46:23Z","timestamp":1724402783000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SHTI240382"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,8,22]]},"ISBN":["9781643685335"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/shti240382","relation":{},"ISSN":["0926-9630","1879-8365"],"issn-type":[{"value":"0926-9630","type":"print"},{"value":"1879-8365","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,8,22]]}}}
