While most of these data are structured, some information, especially concerning the communication between the stakeholders, is typically stored as unstructured free-texts. This paper outlines the differences in analyzing free-texts from the heart failure telehealth network HerzMobil as compared to the diabetes telehealth network DiabMemory. A total of 3,739 free-text notes from HerzMobil and 228,109 notes from DiabMemory, both written in German, were analyzed. A pre-existing, regular expression based algorithm developed for heart failure free-texts was adapted to cover also the diabetes scenario. The resulting algorithm was validated with a subset of 200 notes that were annotated by three scientists, achieving an accuracy of 92.62%. When applying the algorithm to heart failure and diabetes texts, we found various similarities but also several differences concerning the content. As a consequence, specific requirements for the algorithm were identified.<\/jats:p>","DOI":"10.3233\/shti210104","type":"book-chapter","created":{"date-parts":[[2021,5,9]],"date-time":"2021-05-09T12:00:29Z","timestamp":1620561629000},"source":"Crossref","is-referenced-by-count":1,"title":["Natural Language Processing for Free-Text Classification in Telehealth Services: Differences Between Diabetes and Heart Failure Applications"],"prefix":"10.3233","author":[{"given":"Fabian","family":"Wiesm\u00fcller","sequence":"first","affiliation":[{"name":"AIT Austrian Institute of Technology GmbH, Graz, Austria"},{"name":"FH Joanneum, Graz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dieter","family":"Hayn","sequence":"additional","affiliation":[{"name":"AIT Austrian Institute of Technology GmbH, Graz, Austria"},{"name":"Ludwig Bolzmann Institute for Digital Health and Prevention, Salzburg, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karl","family":"Kreiner","sequence":"additional","affiliation":[{"name":"AIT Austrian Institute of Technology GmbH, Graz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernhard","family":"Pfeifer","sequence":"additional","affiliation":[{"name":"AIT Austrian Institute of Technology GmbH, Hall in Tirol, Austria"},{"name":"Landesinstitut f\u00fcr Integrierte Versorgung \u2013 LIV Tirol, Innsbruck, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gerhard","family":"P\u00f6lzl","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine III, Cardiology and Angiology, Medical University Innsbruck, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Kastner","sequence":"additional","affiliation":[{"name":"AIT Austrian Institute of Technology GmbH, Graz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G\u00fcnter","family":"Schreier","sequence":"additional","affiliation":[{"name":"AIT Austrian Institute of Technology GmbH, Graz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","Navigating Healthcare Through Challenging Times"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SHTI210104","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,10,25]],"date-time":"2021-10-25T13:08:09Z","timestamp":1635167289000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SHTI210104"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,5,7]]},"ISBN":["9781643681801","9781643681818"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/shti210104","relation":{},"ISSN":["0926-9630","1879-8365"],"issn-type":[{"value":"0926-9630","type":"print"},{"value":"1879-8365","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,5,7]]}}}
