If short parts of analysed source texts are presented, this may enable third parties to reproduce and verify analysis results – especially in the context of text and data mining. Such short parts of a work may be independently copyrighted, so that their use is subject to copyright restrictions. For example, copying processes may constitute unlawful acts of reproduction under Section 16 Copyright Act. In these cases, the right to make the text available to the public according to Section 19a Copyright Act can also be infringed if the text parts are presented together with the analysis results on the web or to other researchers. In the following, it will be explained in which cases parts of texts are protected by copyright on their own and what additional protection parts of press publications can receive.
