Artifact for the ESEC/FSE 2019 Paper: Effects of Explicit Feature Traceability on Program Comprehension

This is the artifact for our ESEC/FSE 2019 paper "Effects of Explicit Feature Traceability on Program Comprehension", providing 1) the experiment as reusable source code and 2) the anonymized results of our experiment. For more details on how to use the source code and interpret the data, please refer to the readme file.本数据集为发表于ESEC/FSE 2019会议的论文《显式特征可追溯性（Explicit Feature Traceability）对程序理解（Program Comprehension）的影响》的配套研究工件，包含两部分内容：1）可复用的实验源代码；2）经匿名化处理的实验结果。如需了解源代码使用方法与数据解读细节，请参阅自述文件（README）。
