We provide the extracted data for download using a variation of the N-Quads format. For users who prefer other formats, we provide code for converting the download files into CSV and JSON formats, which are supported by a wide range of spreadsheet applications, relational databases and data mining frameworks like the python data analysis library pandas. Please find further details on how to convert the download files to other formats on the main page.
The source code can be checked out from our Github
repository. For more information about the framework and a detailed description how to run a own extraction
visit the framework page.
The code for the analysis of the quads can be checked out from the StructuredDataProfiler Github
repository.
