Abstract:
The research presented examines the use of negation markers in German customer reviews. The objective is to identify differences, as well as similarities in the use of language for reviews rating material products and services. Therefore, in an annotation study, negation markers and sentiment values of customer reviews rating these product categories had to be assigned. The results obtained confirm the hypothesis that customer reviews relating to services contain more negation markers than customer reviews rating material products. However, there exists no significant difference in token distances between the negation marker and the sentiment decisive part of speech (POS). Finally, the findings should be applied in a machine learning algorithm for extracting relevant information from German customer reviews.
