Another rating formula : the energy of the article
-
If you compare the "Top Viewed Articles" with the "Top Ranked Articles", you find that the most popular articles have a relatively low rating. This makes me think that the ranking is not a good parameter, especially for the new competitions ;) I suggest this formula: Energy = rating * log10(max(10,#votes)); In this way an article with "4/5" and 50 votes (energy=6.78) is better that an article with "5/5" and 7 votes only (energy=5) The energy for the top viewed articles will be:

the complete formula was:
rating * log10(max(10,#votes))*exp(-(#days since 1st post)/100))+100*(#clicked banners)+10*(#nish's threads);
but maybe it requires too much processing time for the server ;P

OMG the Nish factor appears ! It appears to be slightly overwieghted at *10. :-) I can see the issue about processor time on the server, for every page refresh. :-) Regardz Colin J Davies

Achieving PostScript and Wmf 25 4.96 6.93Hello Davide, I see that you are doing some R n D on article ratings. I have a humble request. Can you do a case study of my articles. I have always complained to Chris about low ratings and I honestly feel some of it is artificially fabricated! I have 50+ articles and that should give you a wide enough range for comparisons. Most of my articles have good view counts but very poor ratings. Some of them are in the 2s and 3s and I have wondered why warm regards Nish

A case study on your articles based purely on page views, ratings and vote counts won't tell you anything. There are dozens of articles with high vote and view counts with deservedly low ratings, while just as many articles with viewership, high votes and undeserved low ratings. The rating system has been changed to stop multiple votes and to weight votes by membership level. Things will sort themselves out eventually. cheers, Chris Maunder he was a VB programmer, but he got better - Christian Graus

Anyway I've noticed that all my articles posted after you modified the rating system are a lot higher rated than my older ones. So I guess, that shows two things, (1) The rating system has got better and (2) My articles are improving, the improvement might be small, but it's still there ;-) Nish

Hi, The results for the 55 articles are:
overall rating = 3.37 (low)
max energy = 7.60 (good energy - article: Some handy dialog box tricks...)
mean energy = 4.32 (low energy)
articles for beginners = 78%
articles with downloads = 33%Not to be a teacher, or a guru, but I found some common defects in the articles: - Too much articles for beginners: the essay is easy to understand, so the skilled CPians give a low rating. - Too much articles without a playable demo: compile, run, and see what happens is easier than read a good article. - Too much preformatted monolithic blocks: interleaving some text between the source code gives a better appearance. Anyway the overall rating is really too low :confused: :~ , I have another suggestion for Chris: when an author updates his articles, he could choose to reset the rating (with a check-box in the submission wizard, or asking directly to Chris): in this way he loses all the votes (bad and good) and the article has a new chance to climb the charts.

Hello Davide, I am thankful that you have done a case study for me :rose: Davide Pizzolato wrote: - Too much articles for beginners: the essay is easy to understand, so the skilled CPians give a low rating. Yeah, I have realized that by now that beginner level articles are not taken too well down here. Not just from the ratings, but also from the comments! Unless it is on a recent topic so that the majority of people reading it actually gain some information. Davide Pizzolato wrote: Too much articles without a playable demo: compile, run, and see what happens is easier than read a good article. Some of them cannot have a demo of any sort, but I guess you are right. People prefer a downloadable project file zipped rather than code they can copy/paste/modify to compile. Thanks for this suggestion. I had not thought of that before. Davide Pizzolato wrote: - Too much preformatted monolithic blocks: interleaving some text between the source code gives a better appearance. You mean that my sample source code is not spaced properly, eh? Thanks for that too! Anyhow if I actually give them a zipped project file I won't even have to put a lot of code in the actual article, unless they are short samples. Thanks for your valuable tips and pointers Davide. Davide Pizzolato wrote: Anyway the overall rating is really too low Yeah, puzzling as it may sound, that's true. Even allowing for an unpopular collection of articles the rating is till too low as I had voiced previously. But Chris M's new rating system has actually improved things quite a good bit.

Good suggestion, a lot of articles start off poor but authors improve them over time and they become good articles. I second this idea.

I like it (at least for high ranked articles). What about low ranking articles with lots of votes? (guess I could pull out the calculator myself but call me lazy ;)) (apologies for reformatting your post - I wanted others to see your idea more clearly) cheers, Chris Maunder
I think the popularity ratings are biased. They tilts heavily toward MFC articles and toward "cool" subjects like grids. Meanwhile, other articles that are more specialized and receive less total views (and, consequently, less total votes) receive lower "popularity". Frankly, I find it somewhat childish. It takes me back to grammar school days when we voted for the most popular boy and girl in class.

The whole point of the ratigs and popularity is two-fold a) to allow those who have never been to CodeProject before a chance to look over the articles that most people found useful. b) to have something that will give good articles a chance to appear on the homepage longer than would normally be the case. No, it's not perfect, and I'm always up for other ways of accomplishing these two tasks. cheers, Chris Maunder Rub your belly and pat your head simultaneously.
