あれ？一級とか一段は最高なので日本人はそういう風に考えると思ってましたけど。言語能力試験にもそうでしょう。

​> I thought https://dev.tatoeba.org/stats/s...es_by_language was almost OK the way it was. It's the page linked to the top page, right?

​Yes, it's that page.​


​> ​I liked it because it would visitors a clear idea about the corpus and the community.

​That was also my idea.

Initially I wanted to simply add a column that displays the number of corpus maintainer that we have for each language, because I wanted to clearly see how much we can take care of each language, which languages have enough corpus maintainers and which languages don't have any. And perhaps having such stats would encourage more people to try and become corpus maintainers, or search for new members who could become corpus maintainers.

Then I figured, why not display the number of contributors we have for each language, based on their status (admin, corpus maintainer, advanced contributor, contributor). At first I included all language levels, not just the native speakers. But I realised it would make more sense to only include native speakers, since it's not really relevant to see (for instance) that there is one corpus maintainer in Japanese if the level of the corpus maintainer is "beginner".

​Then I wanted to add some warning icon, for languages where we lack corpus maintainers. Perhaps display each language with a different level of warning: big warning when we lack corpus maintainers, smaller warning if we have advanced contributors but no corpus maintainers. Perhaps also green "check" if we have more than 2 corpus maintainers.​

Then I had plenty of other ideas in mind, but this is usually the point where I tell myself I'm getting carried away and I stop.

I also felt that changing the title might be a solution to prevent the confusion, but then it led me to ask myself some questions.
Perhaps dividing the native speakers by status it is too detailed and perhaps it would be enough to either have the total number of native speakers, or maybe just the number of admins + corpus maintainers.
Perhaps there is a way to add some information about the level of expertise we have in each language, which can be an interesting information as well (some languages have many members, but none of them are native, while other languages have only a few members but most of them are native speakers).

In the end I didn't want to spend time deciding on these things, since they are not part of my initial goal, which is why I decided to create a separate page for the native speakers stats because rather than tweaking the current sentences_by_language page. I prefer to give myself more time to think of a new page that would synthesize all the information we have about each language, in a way that is satisfying enough for veteran users, and not too cryptic for new visitors.

But I completely share your vision that it would be much better if the link "all languages" would show more than the number of sentences in each language.

You say that the bars are not useful for languages in the lower part of the graph, but what information do you expect from these bars?

For instance to me, each bar was never meant to be useful on its own. The important information is carried by the whole graph, which is there to give a global view about how the languages are spread within the corpus. If we take the root square or logarithm or whatever, it would give the wrong idea about the weight of the language in the corpus.

If the information that you are looking for is to know "how many sentences do we need to add in a certain language so that it exceeds the language above", then obviously it is not best represented by the current graph. But this kind of information should be implemented as an extra feature, not by replacing the current graph, which in my opinion is not really useless but simply has another purpose.

In any case, for other visualisations of Tatoeba's data, I encourage anyone who has a bit of programming knowledge to use the files that we export[1] and make your own visualisation, just like someone else did for the translations some time ago: https://tatoeba.org/eng/wall/sh...#message_21926
I personally loooove data visualisation but I can't afford to spend time implementing such things in Tatoeba, so I'm counting on other people to do it and share their work with us on the Wall :)
