I second this question. I've also seen Glosbe but haven't contributed to it myself because (1) it is not open source, and (2) it does not (as far as I'm aware) allow for bulk data download.

This is probably not what you want because it is mainly between German and other European languages, but I like dict.cc because they allow you to download the dictionary data in its entirety (but it must be requested by email).

And of course, there is always Wikitionary.

What do you have in mind exactly with "ensuring quality"? Even here on Tatoeba there seems to be quite a bit of debate sometimes when it comes to correcting sentences.

That’s correct, there was never an official Tatoeba app. By the way, I can’t access this group (probably because I don’t have a Facebook account), but I am curious how much the group is used.

You can report them to community-admins@tatoeba.org
Mostly within a few hours the account is deleted.

Thank you for offering your help to deal with spam accounts. At the moment, there are so many of them created every day that I don’t think it is very helpful to deal with them by means of user report. You would have to go through hundreds, if not thousands of them. This is why the functionality to report an account is not there yet. But maybe you want to report some more specific accounts, like old accounts having contributions?

We are trying to first reduce the flow of spam account to a manageable level. You can follow the progress here https://github.com/Tatoeba/tatoeba2/issues/1613, and you are welcome to contribute to this discussion here or on GitHub.

@PaulP, @gillux: thank you for the assistance! I'm aware that one can directly report them to the admins but as @gillux said, there are indeed a lot of spam accounts and it wouldn't be convenient to manually report all of them

I still believe that the ability to report an account may be a useful functionality to have, at least after the amount of spammers goes down to a somewhat manageable level. will make sure to follow the discussion on GitHub as well

Agreed. Also, the length of the entries keeps users from attempting to translate them. Content-wise they're good sentences, mostly. Is there a way to somehow automatically split them up into single sentences?

Tatoeba is not only for translations. It is also useful to find examples of usage in a single language only.

If other contributors are adding long sentences, it probably means they are useful to them. Maybe they are not useful to you, but it doesn’t mean they shouldn’t be on Tatoeba. What should or should not be on Tatoeba is a totally different thing than your own needs.

If you don’t want to see long sentences, you can filter them out from the search by setting a maximum number of words.

Rien n’a changé à ce niveau, si ce n’est que le modèle sur lequel s’appuie la détection des langues est mis à jour chaque semaine sur la base du corpus de Tatoeba (modulo les phrases étiquetées @wrong flag). Le modèle n’est jamais été parfait, notamment sur les phrases courtes.
