  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.
