Each CSV contains information on the metrics: precision, recall and f-measure distributed in three groups of three columns, in total nine columns. Each column shows the best value of the top-n recommendations. Each CSV file corresponds to the evaluation results for the Spark framework using the Local strategy and a different threshold value.We compute the metrics varying the threshold value by 0.1 from 0 to 1, therefore there are 11 csv files.<br>The xlsx file contains the aggregation of the top-1 values of the three metrics: precision, recall and f-measure for each threshold value.The pdf file contains the chart corresponding to the data in the xlsx file.
