More Like This

Hi,

I would like to know what metadata More Like This feature exactly uses and in what order of importance. Can someone elaborate this please? Thanks

[Luke 42078]

Genres, studios, people, rating, year.

[levander 97]

Ok, thanks. I would appreciate if you can answer these questions regarding same thing:

1. Does film that is first in More Like This list has most matches or not necessarily?

2. Do people have some hierarchy or they all count by number of matches?

3. You haven’t mentioned tags... do you plan to include tags in the future?

[Luke 42078]

 The other is based on most matches, then random for any of equivalent value. People is just on number of matches. Tags will be incorporated in the future. Thanks.

[levander 97]

Thanks for the info. TMDb Collection id could be also taken in consideration for suggestions but only if you’re not going to include “this movie is part of collection...” info on movie details page as you told you would.

[levander 97]

Hi. Something’s not right. You said that it is based on most matches then random for any of equivalent value. There are more than few films I would expect to show up in More Like This for given movie (solely on number of people matches) but instead there are films listed that don’t match even one person. And those I would expect to see based on matched people (more than few!) are not even showed and they are also from same studios and have same rating (and in same library). If you want I can give you examples.

The heaviest weighting factor for the matching is genre.  How do the genres compare?

[levander 97]

If you say genre is heaviest weighting factor then I would expect that movie with these genres: Family, Fantasy, TV Movie would first suggest movies with those same or most of those and then taking in consideration people, studio etc. But instead first 3 suggested movies are only matched with two of three: Family and Fantasy, although there ARE films with exact those genres ( which are better matches). Apart those matches there are NONE people, studio, rating matches. But I think director’s (people) name might be matching falsely not matching whole name but only name OR surname.

[Luke 42078]

genres is the highest scoring factor. the matching is all based on id's in the database, so there should not be any problem of partial names matching incorrectly.

Ok, thanks for clearing that up!

It might have highest scoring but the movie that has EXACTLY same genres would not be suggested if it's year (5 years?) and rating are not matched. So rating and year are obviously crucial in suggesting (more important than genre match).

 

Rating system is inconsistent since it varies from country to country and variants of same rating (NR or Not Rated for example) only bring me more headaches and yet there is no guide to explain how rating matching exactly works in emby. Anyway those ratings only messes up suggestions for me most of the time. I don't say it is not useful to make distinction between family friendly movies and excessive violence & gore but in reality it's not working as it should. 

 

Example:

 

If I browse a movie from 2014; Documentary, War; rating: none. These are suggestions: only 2 titles with exactly same genres: Documentary, War; from 2008 and 2006; rating: none. The rest of suggested movies are actually random movies that are also not rated, from 2010-2018 and match only one genre: Documentary.

 

So I mostly got bunch of random documentaries from that period while I have 24 movies that contains Documentary AND War genres and 8 out of those 24 is exactly Documentary, War genres.  Most of them are also not rated at all. But their year span is from 1930-2010 so no match or them?

I think the rating is the biggest problem here.  We try not to suggest items with higher ratings than the one you are looking at.  So, when there are no ratings, we err on the side of caution.

 

If you give these items a rating, I think it will all work better for you.

Wait, what rating are you talking about? What is higher rating? I am talking about parental guidelines and film rating system... right?

I'm saying if you are looking at a movie rated PG we are not going to show R rated ones in the "More Like This" section.

Ok, I understand. But how APPROVED or RATED or NOT RATED apply? Is that higher or lower?

 

It IS problematic (and it should be optional to remove it's influence on suggestions) but the year limiting interference is also - too limiting... I never cared for ratings anyway. It might be interesting or fun to know and compare ratings as part of movie history or trivia but the fact that it (automatically) interferes with suggestions is no fun. Anyway, rating non rated films would be meaningless. Apart from huge library, films that are not rated are just not rated. 

 

 

There IS feature suggestions in emby. And I very much like that feature by default, but it doesn't have to be as simple as this - it could instead be very useful and fun, especially for huge libraries (which you should take in consideration) 

[Luke 42078]

Yes there are improvements that can be made here. Thanks for the feedback.

@@Luke, are tags included in this yet?

[Luke 42078]

Yes.

How does this work for music? Is genre the most important weight?

It's very similar. Genres, common artists are the two biggest factors.

[crusher11 1101]

What data is used to determine similarity?

That thread is five years old and features devs discussing a desire to improve it, so I'd like to think it's changed somewhat.

At a minimum, per a post from Luke in that thread, it now includes tags.

I want to add a question to this topic.

Say I just watched a Film, let's use Jumanji as an example.  Is it expected behaviour for Emby to suggest the same movie , but the trailer and when it is a Live TV programme?

[Gilgamesh_48 1240]

I really wish all "suggestions" could be turned off. Others seem to like them and it seems many use them but the "more like this" is, for me, just an unwelcome intrusion into my viewing experience. 

I have no desire to force others to view the way I do, I just want Emby to actually provide their promise of: "Emby, your media your way." Right now it often seems closer to: "Emby your media our way" and that is not what I would prefer from my media manager. But it is a lot better than the alternatives.

Everything not directly related to finding and showing my media is just "fluff" and I don't want my media to be "fluffy." 

While I understand that the "fluff" is important to many and that things I don't want are important to others and that "options" increase programming complexity I would like to see much of what Emby provides become optional.
