RQ1

Each CSV file corresponds to a framework and a specific strategy and contains information on the metrics: precision, recall and f-measure distributed in three groups of three columas, in total nine columns. Each column shows the best value of the top-n recommendations. There are three strategies and five frameworks, therefore there are 15 files.

每个逗号分隔值（CSV）文件对应一种框架与一种特定策略，其载有精确率（Precision）、召回率（Recall）与F测度（F-measure）三类评测指标的相关信息，该类指标以每组3列的形式划分为3组，总计9列。每一列均展示了top-n推荐任务下的最优结果。本次数据集涵盖3种策略与5种框架，因此共生成15个CSV文件。
