Opinion Spam-Meinungsäußerungen als Fake

Abstract

Customer opinions have become an important business factor. Companies want to know what consumers think of their product and their service trying to quickly adapt themselves and their products to customer needs. They deploy the customer opinions as a marketing tool. Though, with the increase of the relevance of customer opinions, also the number of manipulation attempts increases. This has turned out to be a socially and economically significant problem. This article presents research approaches concerning the English and Chinese languages and examines the transferability of the approaches to the German language. The construction of a corpus for fake reviews in the German Amazon site is outlined. Initial analyses on this corpus show that the methods for English and Chinese are to a large extent transferable to the German language.
