< report >Is is possible to add in vndb a feature like "Similar Games" like exist in anidb and anime network "Similar Animes" ? when I like a Anime I always go to "Similar Anime" and watch similar animes to that anime that I liked. Tags not make the thing, for instance, I like a romantic comedy, but, just looking to romantic comedy games I cannot find a exactly game similar that the one that I liked a lot that I played recently, and not works also to look for a game with the same writer or the same game developer, the others games from the same writer or the same game developer do not have the same quality that the game that I played recently and liked.

I thing should be very nice to add in a game vndb entry page a option the users to suggest similar games.

(MOD edit: this is a VNDB discussion, not a General one.)

< report >I don't know anything about the math involved in those recommendations but they appear to have a heavy skew towards the most popular games on VNDB (possibly because they're basing themselves on the weighted ratings, which means only widely-popular games can have high scores).

Useless for finding hidden gems and obscure games that happen to be similar to a particular favorite of yours.

< report >Personally, I always use "similar novels: VNDB" instead of combined, otherwise the top 200-300 are always Steam releases (like, why should I care if I barely use that store anyways?) or popular VNs before showing western releases.

Useless for finding hidden gems
Visual novels need a minimum of 20 votes to appear as a recommendation in that website. :/Last modified on 2022-04-03 at 00:39

< report >Filtering by votes a system that relies on tags is silly. Less popular VN will be filtered out of the way by simple lack of tags.

It has very finite results (64) so it is probably focused on being relevant. For any seasoned reader, it never works. It was the same with r/visualnovels's reco engine when I tried it.

You can filter your list by tag/trait/producer/staff to have more diversity, like try less used tags. Or check your favs VN. I see you are not very compatible with Empress' games, butterflygirl. :/

< report >User-contributed similar VNs is on the wishlist (d8#4).

Algorithmic similar VNs would be cool if they can be made to work, but several people more qualified than I am have worked on this problem and the results have been... underwhelming. I don't expect we'll be able to improve upon VNstat by much.

< report >#8 I am probably the most qualified person on this site to discuss algorithmic similar VNs

One very simple to implement model would be a topic model like LDA: link

First thing I would try is turning each user into a "document" and the VNs they read + their scores as "words" (so if someone read MLA and gave it a 5/10, and read SayoOshi and gave it a 1/10, their document would be "MLA MLA MLA MLA MLA SayoOshi")

Then, given a new user who wants recommendations, infer their topic distribution given the VNs they've read and their scores. Then you can generate recommendations by repeatedly both sampling from their topic distribution, then sampling from that topic

There are working and easy to use implementations of these things out there: link

If you don't want to use them for some reason, you can do something similar with Singular Value Decompositions, which anyone could program themselvesLast modified on 2022-04-03 at 07:46

< report >@gambs: The data is available in the open, people have tried applying various models to it and the results have been meh. If you feel like there's some more unexplored avenues, go ahead and implement something that provides good practical results.

Ok, joke aside, who found in themselves to go past his first sentence? The cringe fried my brain lol.

< report >All that similarity shit never worked elsewhere. How should the system check the simmilarity? By content/sexual/technical tags? By Characters? By characters gender? By their sexual activity? By their personality?
Too much questions, while the answers are very individual, so you can't put them into one formula, that will work for everyone.

< report >I made a very simple (not optimized in the slightest) recommender here: link

Given my profile it spits out the following recommendations:

[Model was bugged so recommendations were not right, see later posts for updated version]

Edit: this is a demonstration of recommendations for a specific user but similar VNs to a VN is also possible and I’ll show that laterLast modified on 2022-04-04 at 04:21

< report >I think making a public voting system for recommendations like MAL or Anilist works best (allowing both liking and disliking recommendations prevents trolling). I don't think it's necessary, but MAL goes a step further and lets people explain their own recommendation and why it's fitting. Anilist forgoes this since not many people read those anyway. Recommendations will naturally always lean toward more popular works, but generally since vndb has a pretty wide range of taste it should be even more useful than those.

This automatic clustering of VNs is done based on votes alone; no tag information or anything else required

< report >I've also updated the functionality to predict similar VNs to a specific VN (code is still at the same place: link)

For CLANNAD it gives (note many KEY/drama/nakige VNs):

CLANNAD \N
リトルバスターズ! Little Busters!
Kanon \N
シンフォニック=レイン Symphonic Rain
歌月十夜 Kagetsu Tooya
Fate/hollow ataraxia \N
narcissu -SIDE 2nd- \N
車輪の国、悠久の少年少女 Sharin no Kuni, Yuukyuu no Shounenshoujo
ef - a fairy tale of the two. \N
eden* They were only two, on the planet. \N


For Sengoku Rance it gives (note that most are gameplay VNs):

大番長 -Big Bang Age- Daibanchou -Big Bang Age-
恋姫†無双~ドキッ★乙女だらけの三国志演義~ Koihime † Musou ~Doki ★ Otome Darake no Sangokushi Engi~
戦国ランス Sengoku Rance

BUNNYBLACK \N
神採りアルケミーマイスター Kamidori Alchemy Meister
英雄*戦姫 Eiyuu * Senki
BUNNYBLACK2 \N
創刻のアテリアル Soukoku no Arterial
イブニクル Evenicle

For Ore-tachi ni Tsubasa wa Nai ―――under the innocent sky. it gives (note that most of these have difficult Japanese):

Atlach-Nacha \N
俺たちに翼はない ―――under the innocent sky. Ore-tachi ni Tsubasa wa Nai ―――under the innocent sky.
きっと、澄みわたる朝色よりも、 Kitto, Sumiwataru Asairo Yori mo,
クロウカシス ~七憑キノ贄~ Caucasus ~Nanatsuki no Nie~
アザナエル Axanael
神咒神威神楽 Kajiri Kamui Kagura
はるまで、くるる。 Harumade, Kururu.
Fate/EXTRA CCC \N
Photograph Journey \N
相州戦神館學園 万仙陣 Soushuu Senshinkan Gakuen: Bansenjin

Seems to be working to me and I still haven't really tweaked it

< report >What about western Vns, freewares, visual novels made in other languages or those that are available in other language than English or Japanese, Game Jams and indies (or not made by a company).

I just want you to remember that there are people (like me) who likes those kinds of works too, not only those that were made in Japan.Last modified on 2022-04-04 at 02:30

< report >#18 As of now I'm filtering out any VN that got less than 20 votes; it goes without saying that for any statistical method, more data works better than less data

That being said I just tried a random VN from your list, I woke up next to you again., and this is the output:

桜哉 Sakuya
Dahlia-ダーリア- Dahlia
John Cena's Sexy High School Adventure \N
Kyoto Colorful Days \N
レムレスブルーの午前2時 Lemures Blue no Gozen 2 Ji
Your Smile Beyond Twilight \N
I woke up next to you again. \N
Chemically Bonded \N
Our Time \N
Emily is Away <3 \N

I have absoutely no idea how to interpret this output

It's somewhat difficult to find a good value for the "number of topics" hyperparameter in particular, especially since different values will have different behavior (less topics = more uniform/mainstream recommendations in general), but I think the model is doing really well given the small amount of data in the database

Also note that it isn't filtering out things that people have already read (edit: this is now fixed on the github version)Last modified on 2022-04-04 at 05:15
