We are happy to inform you that we have updated the Artist Ranking Algorithm for 2013.
In the past we have had some major changes of the ranking. The most recent one was in August 2012 when we have introduced the points depreciation for past exhibitions. In June 2010 we have strengthen shows that are not related to market interests.
1. Standard competition ranking
Thus, this year have focused on the order of the artists. In the past we have used a Dense ranking ("1223" ranking)
. In dense ranking, items that compare equal receive the same ranking number, and the next item(s) receive the immediately following ranking number. In the Artist Ranking we rank 105,619 different artists but we find only 39,374 different ranking positions. A great number of artists share same ranking positions because they have received exactly the same number of points. The outcome of the dense ranking was sometimes misleading because user expected 1,000 artist names when they wanted a list of the top 1,000 artists.

We have now changed to a Standard competition ranking ("1224" ranking)
to come to a better result in the listings. In competition ranking, items that compare equal receive the same ranking number, and then a gap is left in the ranking numbers.
We have also cut the ranking positions to max. 100,000. As a result the lowest ranking is now 99,996. Before was the lowest position 39,374. The advantage is that the user can more clearly estimate the standing of any particular artist. An artist with an ranking around 50,000 will now be somewhere in the middle position of 100,000 ranked artists.
2. Minimum Three Shows
The distribution of exhibitions and artists is really unfair. The fast majority of artists have only less than 10 exhibitions as you can see on the chart below.
|How many artists have more than one show?|
304,850 artists have had just 1 to 10 exhibitions. Whereas 7 artists have between 1,000 and 2,500 shows. These seven are
We decided to include only artists with a minimum of 3 exhibitions into the ranking to give the Artist Ranking a higher acceptance for the lower ranked artists. 229,967 artist have only one or two exhibitions. We thought that we can not really rank somebody with such a low information basis. 108,057 have more than 3 exhibitions. 8,054 of them are ranked but with a ranking below position 100,000.
3. Lowest Rank is 100,000
A fixed frame of ranks between 1 and 100,000 gives the user a much clearer insight about the positioning of the artist in the ranking. Someone with a rank of 50,000 is in ranking terms based in the middle field.
We think the new Top 100,000 ranking is on the whole a much better than the previous versions.
