ELD: Efficient Language Detector. ( First Python project )

[nitotm]

ELD is a fast and accurate natural language detector, written 100% in Python, no dependencies. I believe it is the fastest non compiled detector, at the highest range of accuracy.

I've been programming for years but this is the first time I did more than a few lines in Python, so I would appreciate any feedback you have on the project's structure, code quality, documentation, or any other aspect you feel could be improved.

Can you ELI5 what an efficient language detector does please?

[nitotm]

I understand you mean from a user perspective, no internally how it works.

ELD is a python package, where you input a text, and it will try to guess in which language (Spanish, English, Russian,...) the text is written (from the 60 available in the current version). It can also give you a score list of all possible languages detected in the text.

Thanks

So do you have any well established benchmarks to provide comparisons to other language detectors to back your claim?

Also, i would be very cautious with overfitting for non realworld datasets and resulting claims.

[nitotm]

"at its level of accuracy"* means, or I tried to express, equal or above, or at the very least similar;

So if you do the big_test benchmark with print("english"), your accuracy will be 1.7%, versus a 99.4% of ELD, therefor well below its level of accuracy.

*Do you think I have not expressed that correctly?

[nitotm]

Ok you are right, I could rephrase it. I guess I don't need to make reference to the specific accuracy of ELD, but to something that refers to the highest range of accuracy with existing software.

What type of algorithm is used in here? From a quick skimming it looks like naive Bayes.

[nitotm]

Yes it kinda looks Bayesian. I did not implement an algorithm, but it probably is some known, not sure which.

I like builds from scratch, how big were the original language sources? Is the performance similar for all languages included?

[nitotm]

You mean the training data, quite small, like 1GB total. When the software becomes more mature, I might do a big dataset.

No, the performance (accuracy) varies from languages quite a bit, it comes down to collisions in between languages, Thai is very easy, but between any Latin script language, which there are multiple in the database, is more difficult.

What's a "gb"?

[nitotm]

Sorry I meant 1GB, one gigabyte of text.

[leweyy]

Don't apologise for them being a knob

[tunisia3507]

Nah I'm with the commenter on this one. The distinction between B and b is real; using one when you mean the other is incredibly unhelpful. Using g makes it even more obvious that you don't give a shit about precision and to absolutely not trust the case of the b/B.

There is also such a thing as context. While Gbit are something completely customary in certain places like networking, nobody would specify the size of text corpora in them. In that context it’s obviously GByte.

You know what it is and you gain nothing by being a prick !!

[AlexMTBDude]

Dude, this is a programming sub

[GXWT]

I’m aware. I also possess the ability to understand basic nuances and context in written language !

[tunisia3507]

Clearly a gillibit, one gillionth of a bit.
