By doing so, they hamper the users\u2019 ability to make informed decisions about using services while ensuring that their data is used properly and fairly. This calls for automatic tools that can effectively identify potentially unlawful policies. Here we present a new corpus of Italian privacy policies, with clauses labelled by experts in data protection law, to indicate the level of comprehensiveness of information. We focus on the categories of data processed, classifying each clause as either sufficiently or insufficiently informative (\u201cvague\u201d). We perform 6 different classification and detection tasks, comparing the performance of BERT-based models and generative Large Language Models. Addressing multilingualism is crucial in the EU, whose 24 spoken languages are an integral part of its cultural heritage. Consequentely, we also perform cross-language experiments to evaluate whether a pre-existing English corpus or classifiers can be leveraged for Italian and, vice versa, whether our corpus is informative enough to generalize to other languages.<\/jats:p>","DOI":"10.3233\/faia251362","type":"book-chapter","created":{"date-parts":[[2025,10,22]],"date-time":"2025-10-22T09:59:27Z","timestamp":1761127167000},"source":"Crossref","is-referenced-by-count":0,"title":["Detecting Vague Clauses in Italian Privacy Policies Using Transformers, LLMs, and Cross-Lingual Techniques"],"prefix":"10.3233","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7255-9343","authenticated-orcid":false,"given":"Giulia","family":"Grundler","sequence":"first","affiliation":[{"name":"CIRSFID Alma-AI, Faculty of Law, University of Bologna, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-5815-4313","authenticated-orcid":false,"given":"Mariaceleste","family":"Musicco","sequence":"additional","affiliation":[{"name":"CIRSFID Alma-AI, Faculty of Law, University of Bologna, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9711-7042","authenticated-orcid":false,"given":"Andrea","family":"Galassi","sequence":"additional","affiliation":[{"name":"DISI, University of Bologna, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7083-3487","authenticated-orcid":false,"given":"Francesca","family":"Lagioia","sequence":"additional","affiliation":[{"name":"CIRSFID Alma-AI, Faculty of Law, University of Bologna, Italy"},{"name":"European University Institute, Law Department, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2417-3219","authenticated-orcid":false,"given":"R\u016bta","family":"Liepi\u0146a","sequence":"additional","affiliation":[{"name":"CIRSFID Alma-AI, Faculty of Law, University of Bologna, Italy"}]},{"given":"Giorgio","family":"Resta","sequence":"additional","affiliation":[{"name":"Department of Law, University of Roma Tre, Italy"}]},{"given":"Sara","family":"Roccu","sequence":"additional","affiliation":[{"name":"Department of Law, University of Roma Tre, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2210-0398","authenticated-orcid":false,"given":"Giovanni","family":"Sartor","sequence":"additional","affiliation":[{"name":"CIRSFID Alma-AI, Faculty of Law, University of Bologna, Italy"},{"name":"European University Institute, Law Department, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9253-8638","authenticated-orcid":false,"given":"Paolo","family":"Torroni","sequence":"additional","affiliation":[{"name":"DISI, University of Bologna, Italy"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","ECAI 2025"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA251362","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,22]],"date-time":"2025-10-22T09:59:27Z","timestamp":1761127167000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA251362"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,10,21]]},"ISBN":["9781643686318"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia251362","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,10,21]]}}}
