Effort Estimation: Openeffort

Data

There are two types of data associated with this paper: author activity from OpenStack contributors and survey data from the contributors. In addition, the raw data from which the author activity data was extracted can be found here

Author Activity Data

-Rows represent individual authors (1626 total) -Columns represent months starting in Jan 2010 (these are 0-padded before and after project) -The actual author IDs can be found by cross-referencing output_authors_ids_nobots.csv: -Number of commits per month: output_commits_nobots.csv -Number of active days per month: output_activity_nobots.csv

Survey Response Data

This represents voluntary responses to a survey in which 131 individuals responded. Survey questions are as follows: ``` 1) Selection: On average, how many hours in a week have you spent in the project in the last six months? (>40h, 40h, 30h, 20h, 10h, <5h)

2) Selection: How much of the time you spent in the project is devoted to coding? (>95%, approx. 75%, approx. 50%, approx. 25%, <10%)

3) Selection: Do you make at least one commit to the repository the days you code? (yes, no)

4) Selection: What do you consider yourself in the project? (full-time, part-time, occasional contributor)

5) Free-text box: Did you always work on the project the same amount of hours, or did you have different phases of commitment? If you had different phases, could you tell us about the various phases? (the graph below may help you, as it is based in your recorded activity in the repository) ```

This survey data was cleaned with a few respondents being removed and some responses being edited. A description of the cleaning process as well as the cleaned response data is here.

# 数据集
本文关联两类数据集：OpenStack贡献者的作者活动数据，以及贡献者调研数据。此外，用于提取作者活动数据的原始数据源可在此处获取。

## 作者活动数据
- 每行对应一位独立作者（共计1626位）
- 每列代表一个自然月，起始时间为2010年1月（项目周期前后的月份均做了0填充处理）
- 实际作者ID可通过与`output_authors_ids_nobots.csv`交叉引用获取
- 月度代码提交次数数据存储于`output_commits_nobots.csv`
- 月度活跃天数数据存储于`output_activity_nobots.csv`

## 调研响应数据
该数据集包含131名参与者的自愿调研反馈。调研问题如下：

1) 选择题：过去六个月中，你平均每周在该项目中投入多少小时？（选项：>40h、40h、30h、20h、10h、<5h）
2) 选择题：你在项目中投入的时间有多少比例用于编码？（选项：>95%、约75%、约50%、约25%、<10%）
3) 选择题：你进行编码的当日是否至少向代码仓库提交过一次代码？（选项：是、否）
4) 选择题：你如何定位自己在该项目中的身份？（选项：全职贡献者、兼职贡献者、临时贡献者）
5) 自由文本题：你在项目中的工作时长是否始终保持一致？是否存在不同的投入阶段？若存在，请详细说明各阶段的投入情况（下方图表或可提供参考，该图表基于你在代码仓库中的活动记录生成）

本调研数据经过清洗处理：剔除了部分无效受访者，并修正了部分反馈内容。数据清洗流程说明与清洗后的响应数据集可在此处获取。
