If you translate the article might be taken down, because still the research or work of someone else, one trick that you can use is pass the same text several times through the translator program, example, from english to spanish, from spanish to german, from german to French, from French to Japanese and then English again and if you compare the original text to the one you had now should be totally different you will have to read and make a few changes nothing is perfect but might save you a lot of time and work.
