While the adoption of Linked Data technologies has grown dramatically over the past few years, it has not come without its own set of growing challenges. The triplification of domain data into Linked Data has not only given rise to a leading role of places and positioning information for the dense interlinkage of data about actors, objects, and events, but also led to massive errors in the generation, transformation, and semantic annotation of data. Though types of errors range substantially, systematic errors often offer the most interesting research opportunities. This work presents the first comprehensive study of these systematic errors and their potential causes. It also discusses lessons learned and means to avoid some of these issues in the future.
