Appendix of Empirical Study of Co-Renamed Identifiers

This data contains four CSVs: Rename.csv, Rename_Ignore_Inflection.csv, Relation.csv, Relation_Ignore_Inflection.csv. Rename.csv and Rename_Ignore_Inflection.csv contain renamings used in our study. The difference between these CSVs is whether we ignored inflections. Each row represents a renaming. Columns descriptions are below. repository: repository name commit: commit hash filepath: location of the renamed identifier oldname: identifier name before the renaming newname: identifier name after the renaming type: identifier type (Class, Method, Attribute, Parameter, Variable) operational_chunk: operational chunks of the renaming meaningful_rename_set_id: meaningful rename set IDs (independent for each repository) Relation.csv and Relation_Ignore_Inflection.csv contain relationships detected in our study. The difference between these CSVs is whether we ignored inflections. Each row represents a relationship between renamed identifier 1 and renamed identifier 2. Columns descriptions are below. repository: repository name meaningful_rename_set_id: meaningful rename set IDs (independent for each repository) commit: commit hash relation: type of relationship file{1,2}: location of the identifier oldname{1,2}: identifier name before the renaming newname{1,2}: identifier name after the renaming type{1,2}: identifier type (Class, Method, Attribute, Parameter, Variable)本数据集包含四个CSV文件：Rename.csv、Rename_Ignore_Inflection.csv、Relation.csv以及Relation_Ignore_Inflection.csv。 Rename.csv与Rename_Ignore_Inflection.csv包含本研究中使用的标识符重命名记录。二者的差异在于是否对词形变化（inflection）进行了忽略处理。每一行对应一条重命名记录，各字段说明如下： repository：仓库（repository）名称 commit：提交哈希值（commit hash） filepath：重命名标识符的所在文件路径 oldname：重命名前的标识符名称 newname：重命名后的标识符名称 type：标识符类型（type），可选值包括Class（类）、Method（方法）、Attribute（属性）、Parameter（参数）、Variable（变量） operational_chunk：该重命名的操作块 meaningful_rename_set_id：有意义重命名集ID（meaningful_rename_set_id），每个仓库的该ID相互独立 Relation.csv与Relation_Ignore_Inflection.csv包含本研究中检测到的标识符间关联关系。二者的差异同样在于是否忽略了词形变化。每一行对应两条重命名标识符间的一条关联关系，各字段说明如下： repository：仓库（repository）名称 meaningful_rename_set_id：有意义重命名集ID（meaningful_rename_set_id），每个仓库的该ID相互独立 commit：提交哈希值（commit hash） relation：关联关系类型 file{1,2}：标识符所在的文件路径 oldname{1,2}：对应标识符重命名前的名称 newname{1,2}：对应标识符重命名后的名称 type{1,2}：对应标识符的类型，可选值包括Class（类）、Method（方法）、Attribute（属性）、Parameter（参数）、Variable（变量）
