SourceForge has enhanced its review and rating system over the past several months. This involves moving from our current Thumbs Up/Down recommendation system to a more robust 5-star review system. We believe the new system allows users a more expressive way to rate and review a project and gives our projects a better understanding of their reviews.
We have performed this move to the new system in stages. With our last update, the number of ratings weren’t matching the numbers of reviews because we were displaying the old recommendation counts. Today we have released an update to display the individual ratings in the same way we were displaying the recommendations and also fixed several minor issues. We believe this will make for a great review and rating experience for users and project administrators.
With this latest update, we have mapped all the previous Thumbs Up ratings to 5-star ratings and all the previous Thumbs Down to 1-star ratings. This will create the base for the average rating score you will see for your project. You will notice in the image above that you are only seeing mostly 5 or 1 star ratings.
As project owners on SourceForge, as ratings begin to fill out, you will be able to get a detailed understanding of how people feel about your project. You will of course also see the reviews associated with each rating and be able to clearly identify the experiences that are common between a 5 or 4 star rating and a 2 or 1 star rating. The advantage here is narrowing the information down and getting specifics about what is making your users happy and what is not.
Also, this will not change how the search and browse rankings that projects currently receive work. Internally ratings of 3-star or higher become a +1 and ratings of 2-star or lower become a -1 and those rankings will still be calculated in the exact same way we calculate them now; using lower bound of the Wilson score confidence interval for a Bernoulli parameter (you can read about it here).
We would love your feedback on how to keep enhancing this Reviews experience on SourceForge, so leave a comment or drop a line to CommunityTeam@sourceforge.net.
