  1. Different SPARQL queries were executed in the knowledge graph to interrogate specific information from the provenance of all the files that stored ISI histograms computed from artificially generated data. Aggregations of the query results are presented according to the range of the numbers in the file names (i.e., 1–100 refers to all consecutive files with the name between “1.png” and “100.png”). (A) SPARQL query to identify the step class used to generate the artificial data for which the ISIHs were computed. The first 100 files used spike trains generated by a stationary Poisson process, while the last 100 files used spike trains generated by a gamma process. (B) SPARQL query identifying the class and value of the parameters used by executions of a function that generated artificial data. All 200 files used a target firing rate of 10 Hz, but the generation of the spike trains of the last 100 files (by a gamma process) used a shape factor of 1 (equivalent to a Poisson process). (C) SPARQL query asking for the bin size parameter during the computation of an ISIH from artificially generated data. All 200 files contain histograms with a 10 ms bin size. (D) SPARQL query identifying the class of the step that performed the spike interval variability analysis. All 200 result files used the CV2 statistic. In all tables, the prefixes of the full IRIs of the NEAO classes returned by the queries were substituted by the namespaces according to Table 1.
