The data that will be used from the participants for training purpose correspond to an experiment run of Versioning Benchmark v2.0 on HOBBIT platform, having the following configuration parameters: Generated data form Both (IC+CS) A seed for data generation 100 Version Deletion Ratio (%) 3 Initial version size (in triples) 100000 Version Insertion Ratio (%) 5 Number of versions 5 This folder contains the following folders: data: This folder includes all generated data in both forms of Independent copies and Changesets. In more details, in the subdirectory changesets there are 5 subdirectories of the form of /c{VERSION_NUM} that contain the files of the change-sets with respect to the previous version. Such files are of the form of *.added.nt or *.deleted.nt. The former include the triples that have to be added to the previous version and the later the triples that have to be deleted from the previous version, in order to compose the VERSION_NUM version. In the subdirectory independentcopies, there are 5 subdirectories of the form of /v{VERSION_NUM} that contain the files that contain the final triples of each version. query_templates: In this folder, for each one of the eight different query types, as these are described in Section 2.2 of D5.2.1_First_Version_Versioning_Benchmark: https://project-hobbit.eu/wp-content/uploads/2017/06/D5.2.1_First_Version_Versioning_Benchmark.pdf, there is one or more query templates. Such templates are the queries themselves, including mustache templates of the form of {{{template}}}. These templates can be compiled (replaced) using the substitution_parameters contained in /substitution_parameters folder. substitution_parameters: The different parameters that used for compiling the mustache templates {{{template}}} contained in the query_templates, in order to get the final query for execution. Note that for QT1 there is only one substitution parameter as it asks for the current version materialization. queries: This folder contains the final queries after compiling the mustache templates using the parameters contained in substitution_parameters directory. expected_results: The expected results of all queries, serialized into JSON format.
