Example of a JSON training data configuration file

Here is a sample training data configuration file that describes a graph for a node-classification task:

{ "version" : "v2.0", "query_engine" : "gremlin", "graph" : [ { "edges" : [ { "file_name" : "edges/(movie)-included_in-(genre).csv", "separator" : ",", "source" : ["~from", "movie"], "relation" : ["", "included_in"], "dest" : [ "~to", "genre" ] }, { "file_name" : "edges/(user)-rated-(movie).csv", "separator" : ",", "source" : ["~from", "movie"], "relation" : ["rating", "prefixname"], # [prefixname#value] "dest" : ["~to", "genre"], "features" : [ { "feature" : ["rating", "rating", "numerical"], "norm" : "min-max" } ] } ], "nodes" : [ { "file_name" : "nodes/genre.csv", "separator" : ",", "node" : ["~id", "genre"], "features" : [ { "feature": ["name", "genre", "category"], "separator": ";" } ] }, { "file_name" : "nodes/movie.csv", "separator" : ",", "node" : ["~id", "movie"], "features" : [ { "feature": ["title", "title", "word2vec"], "language": ["en_core_web_lg"] } ] }, { "file_name" : "nodes/user.csv", "separator" : ",", "node" : ["~id", "user"], "features" : [ { "feature": ["age", "age", "numerical"], "norm" : "min-max", "imputation": "median", }, { "feature": ["occupation", "occupation", "category"], } ], "labels" : [ { "label": ["gender", "classification"], "split_rate" : [0.8, 0.2, 0.0] } ] } ] }, "warnings" : [ ] ] }
