I'm doing a lot of research in the field of Digital Text Forensics (e.g., authorship attribution, authorship verification or author profiling). In this field there are only very few data sets available, which can be used for own research. One of the few important sources is the evaluation lab on uncovering plagiarism, authorship, and social software misuse (named as PAN).
Over the years, I collected texts from many different internet sources (Blogs, Forums, Amazon, News portals, Project Gutenberg, etc.) by my own, which I aggregated and compiled into various data sets that could be very valuable for the Digital Text Forensics community. Since, as a researcher, I am very interested to share data in order to make experiments reproduceable, I'm facing now a big problem, which I don't know how to handle...
How/Can I share my data sets, without worrying about copyright issues?
It should be also highlighted that the data cannot be anonymized, otherwise it would be totally useless for the research community. Hence, I don't know where to start. Of course there are plattforms such as FigShare, where data sets can be published, but if I would do this I would first don't get any credit and second can run in alot of troubles for publishing texts, which are not mine (even though they are publicly available).
Has someone else faced this problem?
