I have a newssystem where you can rate News with 1 to 5 stars. In the Database i save the count, the sum and the absolute rating as int up to 100 (for html output, so 5 stars would be 100 1 star would be 20percent. Now i have three toplists: Best Rated Most viewed Most commented
Last two ones are simple, but the first is kinda tricky. Before i took that thing over it was all a big mess, and they just put the 5 best rated news there, so in fact if there was a news rated 4.995 with 100k votes and another one with 5 stars at 1 vote, the "better rated" one is on top even if that is obv ridiculous. For the first moment i capped the list so only news with a certain amount of votes (like 10 or 20) can be in the list.
But i do not really like that. Is there a nice method to kind-a give those things a "weight" with the count or something like that?

Ranking models typically work by predicting a relevance score s = f(x) for each input x = (q, d) where q is a query and d is a document. Once we have the relevance of each document, we can sort (i.e. rank) the documents according to those scores. Ranking models rely on a scoring function. (
To create a ranking survey, create a survey as normal, and then add a ranking question where you see fit. You can toggle between the standard ranking and click ranking as needed. You can add an unlimited number of attributes to each ranking question.
A ranking algorithm is a procedure that ranks items in a dataset according to some criterion. Ranking algorithms are used in many different applications, such as web search, recommender systems, and machine learning.

Have you considered using a weighted bayesian rating system? It'll weight the results based on the number of votes and the vote values themselves.
