Ratings: Add extra level of precision for sorting IMDb ratings

Since the launching of the new advanced title search there is a problem that persists and you didn't even answer the other times I've post about it. When I use the advanced title search to look for movies in IMDb rating order, all the movies with the same rating number appear in popularity order instead. Ex: all the movies with 6.9 appear in popularity order instead of rating order, so we don't know which movies are closer to 6.8 and which movies are closer to 7.0. If we want an accurate rating order we must create a list first and only then we can see a correct rating order. I'd like to see the correct rating order using the advanced title search, the way it was before. You are overlooking some serious issues on the site, like the indian/turkish bad movies invasion on top 250. IMDb is not the way it was anymore, unfortunately.

Do you have an example of an advanced search result with this problem and then an equivalent list which you think shows sorting by an extra degree of precision?

Hi. It's more simple than that. For example: go to advanced title search, look for movies of 1970-1979 with a 7.0 rating and a minimum of 5000 votes. The results by IMDb rating and by Popularity will be in the exactly same order. Just check it out. Thanks.

So you are saying http://www.imdb.com/search/title?release_date=1970,1979&title_type=feature&user_rating=7.0,7... is the same as http://www.imdb.com/search/title?release_date=1970,1979&title_type=feature&user_rating=7.0,7...

This is not a problem.  The IMDb ratings only go to a precision of one decimal place. If you thought the old advanced search was going to an extra level of precision then you were mistaken; previously the orders may have been different because sort by rating would sort titles with the same rating either randomly or possibly by IMDb ID number (by the "tt" value in the URL). 

Can you please explain further about using lists to generate another sort order?

No, my friend. The old advanced title search was precise. If a movie was on the top of a list like that, soon it would change its rating for better if it was on a crescent tendency. I'm an expert on IMDb. Use it since 1995. :-) I have a "Classics" list. If I go to "my lists", click on "Classics" and the option "sort by IMDB rating", all the movies will appear in an exactly rating order, including those that have the same rating number. I know it because I control the ups and downs of these movies. If only you had some way to check it. Anyway, I'm going to put a link to the advanced title search results for the movies on the list with 8.5 and a link to my complete list sorted by precise rating order (on that link, just scroll down a little to check the 8.5 movies and compare)

Or: I include on this list only 7.0 + movies. So, I used the advanced title search to see which 6.9 movies were on a crescent tendency and closer to 7.0. It never failed: a movie with a crescent tendency and on the top of the list, soon would go to 7.0. I bet my life on it. :-)

Okay so your claim is that of all the movies rated 8.5 on IMDb, if you could see an extra digit of precision then the order would be #1 The Green Mile #2 Psycho #3 Raiders of the Lost Ark #4 Rear Window #5 The Pianist ?

I personally wrote the second generation ratings calculation software in the early 1990s and it only published ratings to one tenth of a ratings point. When we rebuilt advanced search recently again we only have access to tenths of ratings point.  Let me check what is happening with the list sorting and get back to you as it is easy to get answers on working software rather than a retired system like the old advanced search.

Of all the movies rated 8.5 on IMDb probably not, but this would be the exact rating order of the movies rated 8.5 that I've selected for my "Classics" list, meaning that The Green Mile, at the moment, is closer to the 8.6 rating than the others. Got it?

And what about this problem, Col, that has increased with the changes on the personal lists? Now it is impossible to obtain the correct IMDb rating order in any place.

Hey, Col. You really should look on this matter. The ratings system was accurate but since you've changed the "advanced title search" and the "lists", it's not anymore. Look the post below, by Aaron. Please, I really liked to see my movies in an accurate rating order.

This reply was created from a merged topic originally titled Sorting Titles by IMDb Rating.

When sorting titles by IMDb Rating using the advanced title search, it only sorts titles by their shortened 1 d.p. score (the one shown on their main page) rather than their exact score. It then sorts titles with the same 1 d.p. score by their popularity. This is inaccurate and misleading.

The two images below illustrate this problem. The lists are in identical order. Thor: Ragnarok is shown as the highest rated title with 8.2 but it is actually just the most popular. As an example, titles with 8.29 should be sorted higher than those with 8.21.

Just checked today with 8.2-scoring films and it still ranks them by popularity when it's sorted by IMDb rating. Also the top 8.2 is Dunkirk at 8.1.

I should point out that using the old 'Your Ratings' page (before the recent update) it was in fact possible to sort titles by their exact IMDb rating -- i.e. with far greater precision than just 1 d.p.. This was apparent since films on an upward or downward trajectory would move up or down the list accordingly. For example, True Romance was the lowest rated 8.0 but recently became the highest rated 7.9.

This is a genuine problem and it should be looked into.

I realised it is still possible to sort titles by their exact IMDb rating by creating a list. The image below helps demonstrate this. Notice that their order by IMDb rating is nearly identical to their order on the Top 250, which would be logical -- titles with a higher exact rating will obviously rank higher. Any minor differences are due to the formula applied on the Top 250. Surely this proves that titles can be sorted by IMDb rating to greater precision than 1 d.p.

Since they changed the lists systems, it is not possible anymore.

This reply was created from a merged topic originally titled IMDb rating order. AGAIN..

It looks like IMDb don't give a damn anymore to the fact that when we search for movies in IMDb users rating order all the movies with the same rating appear in POPULARITY ORDER. The way it was before, for example, on a list of movies with 6.9 the first movie was the closest to 7.0 and the last was the movie closest to 6.8. Now most people don't know about this issue and believes that all the lists are accurate. They are not. If I search for the best 200 movies with 6.9, I will get a completely different list from the one I really want, with 200 movies displayed in POPULARITY ORDER. Please, let me ask again: correct this. Give me back the reliable site that IMDb once was. Thanks.

The rating order on IMDb used to be accurate in the "advanced title search" and in the lists. Now, when I search for the highest rated titles on a list or in the "advanced title serch", all the movies with the same rating appear in popularity order. When I use the "advanced title search", for example, to find the best movies with 7.6 in any given list, the results are display in popularity order. I talk about this now and again, but you guys seem to don't care. You are given wrong results to the users and most of them don't even know that the results are wrong. You should think about that. It takes only a software adjust, people. When I get a result that reads "Highest Rated Titles In Your List With User Rating of 7.6" I want exactly what it says, not a popularity order result. Thanks.

I'm still waiting for an answer about the ratings problem. When we search for movies in IMDb rating order, the movies with the same rating number are appearing in POPULARITY order. The search system and the lists used to be accurate. Col Needham said that he would personally see about this, but he never answered anymore. I don't understand how the founder/CEO of IMDb can overlook such a serious problem: the fact that users can't generate a list with an accurate rating order anymore.

This reply was created from a merged topic originally titled Ratings: Display a second and maybe a third decimal place to IMDb film/TV ratings....

I love IMDB and one thing that I would like to see is IMDB display a second and maybe a third decimal place when they display their user ratings.  This is NOT for user to rate a movie.  For example, if I watch  a movie I should not be able to rate a movie a 7.42 or a 7.423.  But when IMDB takes the combined ratings of users for a movie, they should be able to list it as a 8.65 or an 8.647 instead of an 8.6.
