SCARE - The Sentiment Corpus of App Reviews with Fine-grained Annotations in German

The SCARE corpus consists of fine-grained annotations for mobile application reviews from the Google Play Store. For each user review the mentioned application aspects, i.e., the design or the usability, as well as subjective phrases, which evaluate these aspects, are annotated. In addition, the polarity (positive, negative or neutral) of each subjective phrase is recorded as well as the relationship of an aspect to the main app in discussion. Aspects which refer to an app or an aspect of an app other than the app in discussion are marked as “foreign”. All other aspects are “related”. In total, the corpus consists of 1,760 German application reviews with 2,487 aspects and 3,959 subjective phrases.
