[{"abstract":[{"text":"This paper aims at discussing past limitations set in sentiment analysis research regarding explicit and implicit mentions of opinions. Previous studies have regularly neglected this question in favor of methodical research on standard-datasets. Furthermore, they were limited to linguistically less-diverse domains, such as commercial product reviews. We face this issue by annotating a German-language physician review dataset that contains numerous implicit, long, and complex statements that indicate aspect ratings, such as the physician’s friendliness. We discuss the nature of implicit statements and present various samples to illustrate the challenge described.","lang":"eng"}],"ddc":["006"],"user_id":"58701","keyword":["Sentiment analysis","Natural language processing","Aspect phrase extraction"],"publication":"Proceedings of the Fourteenth International Conference on Pervasive Patterns and Applications (PATTERNS 2022): Special Track AI-DRSWA: Maturing Artificial Intelligence - Data Science for Real-World Applications","file_date_updated":"2022-12-01T13:39:48Z","publisher":"IARIA","author":[{"id":"58701","last_name":"Kersting","full_name":"Kersting, Joschka","first_name":"Joschka"},{"full_name":"Bäumer, Frederik Simon","first_name":"Frederik Simon","id":"38837","last_name":"Bäumer"}],"file":[{"creator":"jkers","file_id":"34172","file_size":155548,"success":1,"relation":"main_file","content_type":"application/pdf","date_updated":"2022-12-01T13:39:48Z","date_created":"2022-12-01T13:39:48Z","file_name":"Kersting & Bäumer (2022), Kersting2022.pdf","access_level":"closed"}],"date_created":"2022-05-04T08:12:09Z","has_accepted_license":"1","status":"public","conference":{"name":"The Fourteenth International Conference on Pervasive Patterns and Applications (PATTERNS 2022)","start_date":"2022-03","location":"Barcelona, Spain"},"_id":"31054","page":"5-9","citation":{"short":"J.
