Automatically Extracted SHACL Shapes for WikiData, DBpedia, YAGO-4, and LUBM & Associated Coverage Statistics - Lissandrini, Matteo; Hose, Katja; Rabbani, Kashif (Zenodo, 2022)
The uploaded datasets contain automatically extracted SHACL shapes for the following datasets: WikiData (the truthy dump from September 2021 filtered by removing non-English strings) [1] DBpedia [2] YAGO-4 [3] LUBM (scale factor 500) [4] The validating shapes for these datasets are generated by a program that parses the corresponding RDF files (in `.nt` format). The extracted shapes encode various SHACL constraints, e.g., sh:minCount, sh:path, sh:class, sh:datatype etc. For each shape we encode coverage in terms of number of entities satisfying such shape, this information is encoded using the void:entities predicate. We have provided as executable Jar file the program we developed to extract these SHACL shapes. More details about the datasets used to extract these shapes and how to run the Jar are available on our GitHub repository https://github.com/Kashif-Rabbani/validatingshapes.
