These communities create networks of mutual support that cover different cancer-related topics, containing an extensive amount of heterogeneous information that can be mined to get useful insights. This work presents a case study where users\u2019 posts from an Italian cancer patient community have been classified combining both count-based and prediction-based representations to identify discussion topics, with the aim of improving message reviewing and filtering. We demonstrate that pairing simple bag-of-words representations based on keywords matching with pre-trained contextual embeddings significantly improves the overall quality of the predictions and allows the model to handle ambiguities and misspellings. By using non-English real-world data, we also investigated the reusability of pretrained multilingual models like BERT in lower data regimes like many local medical institutions.<\/jats:p>","DOI":"10.3233\/shti220147","type":"book-chapter","created":{"date-parts":[[2022,6,7]],"date-time":"2022-06-07T09:32:58Z","timestamp":1654594378000},"source":"Crossref","is-referenced-by-count":0,"title":["Improving Keyword-Based Topic Classification in Cancer Patient Forums with Multilingual Transformers"],"prefix":"10.3233","author":[{"given":"T.M.","family":"Buonocore","sequence":"first","affiliation":[{"name":"Department of Electrical, Computer and Biomedical Engineering, University of Pavia, Pavia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Parimbelli","sequence":"additional","affiliation":[{"name":"Department of Electrical, Computer and Biomedical Engineering, University of Pavia, Pavia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L.","family":"Sacchi","sequence":"additional","affiliation":[{"name":"Department of Electrical, Computer and Biomedical Engineering, University of Pavia, Pavia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.","family":"Bellazzi","sequence":"additional","affiliation":[{"name":"Department of Electrical, Computer and Biomedical Engineering, University of Pavia, Pavia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L.","family":"del Campo","sequence":"additional","affiliation":[{"name":"AIMAC, Italian Association of Cancer patients, relatives and friends, Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Quaglini","sequence":"additional","affiliation":[{"name":"Department of Electrical, Computer and Biomedical Engineering, University of Pavia, Pavia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","MEDINFO 2021: One World, One Health \u2013 Global Partnership for Digital Innovation"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SHTI220147","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,6,7]],"date-time":"2022-06-07T09:32:58Z","timestamp":1654594378000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SHTI220147"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,6,6]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/shti220147","relation":{},"ISSN":["0926-9630","1879-8365"],"issn-type":[{"value":"0926-9630","type":"print"},{"value":"1879-8365","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,6,6]]}}}
