$ python clean.py
Running above command will create first_reviews.csv
file in the data directory. The resulting csv file will only contain the columns that are relevant to future analyses. These include:
Field Name | Description |
---|---|
review_id | Unique identifier for all reviews |
submission_id | Unique identifier for all papers that are being reviewed |
member_id | Unique identifier for each member of the reviewers |
member_name | Name of the reviewer |
phd_year | Year in which the reviewer received his/her PhD |
track | Academic track the reviewer is in |
score | The overall score for the review |
bias | The bias score of the review |
review_length | Length of the actual review text |
review_datetime | Review submission datetime |
These columns have been renamed from #
, submission #
, and member #
for better readability.
Instead of having two columns for first and last names each, they have been consolidated into one.
This column only includes the review scores for the "Overall" field. As such, scores for other fields, such as Audience, Confidence, and Alternatives, have been dropped.
These columns are the metrics used to conduct future analyses. For details on calculating bias, please refer to this section.
This column contains Python datetime objects. It is only used to identify the first reviews per submission per reviewer.
The bias is a metric that calculates how much the reviewer's score differs from the rest of the reviews for the same submission. The following formula is used to calculate the bias:
biasi, j = meanj * Nj - scorei, j / (Nj - 1)
where i is the reviewer ID, j is the submission ID, and Nj is the number of reviews given for the submission j.
The distribution of the bias, absolute bias, and review length are visualized using violin plots. The following command should create bias_to_phd.png
and revlen_to_phd.png
in the data
directory:
$ python bias_revlen_to_phd.py
This image contains two sets of violin plots, each for the bias and absolute bias, respectively. Both sets are separated by PhD years, and all the data above 2018 have been clumped into one 2018+
category.
This image contains a violin plot that is similar to those in bias_to_phd.png
, but for review lengths. The representation of the PhD years (x-axis) remains the same.
The distribution of the bias, absolute bias, and review length are visualized using violin plots. the following command should create bias_to_track.png
and revlen_to_track.png
in the data
directory:
$ python bias_revlen_to_track.py
This image contains two sets of violin plots, each for the bias and absolute bias, respectively. Both sets are separated by tracks.
This image contains a violin plot that is similar to those in bias_to_track.png
, but for review lengths. The representation of the tracks (x-axis) remains the same.
