Graphs of redirection: an examination of URIs in identity graphs (Q6718026)

This is the dataset for our paper What does it mean when your URIs are redirected? Examining identity and redirection in the LOD cloud Redirection of URIs is widely used in the LOD cloud, and is even part of the best practice guidelines as an approach to the ``curation problem on the semantic web (i.e. how to repair imperfections). When dereferencing, one URI is redirected to another URI. Such a redirection could be the result of an update of the namespace, a different encoding scheme, or some other reasons. In this paper, we study the semantics of redirection and examine if redirection indicates how entities in the LOD cloud evolve. More specifically, we focus on entities in the identity graphs: subgraphs in the semantic web restricted to identity links. The entities we study are from sameAs.cc, an identity graph extracted from a crawl of the semantic web in 2015. Our analytical results include an examination of edges and chains of redirection as well as a statistical analysis of the redirection behavior of sampled entities. Additionally, we present properties of the graphs formed by redirection relations. The dataset contains the redirect relations of four sets ofsampled entities.These sampled files are: ite_uniform... the edges of redirection graph corresponding to uniform samplings cc_sample_2... the sampling regarding connected components of size 2, 3-10, 10+, respectively.
