问题描述
我有许多代表不同语言的句子的字符串(字符集合),说:
I have a number of strings (collections of characters) that represent sentences in different languages, say:
你好,我叫乔治.
Hello, my name is George.
Das brot ist肠道.
Das brot ist gut.
...等等
我想给它们中的每一个分配分数(从0 .. 1开始),以表明它们是英语句子的可能性.是否有可以从中执行此操作的算法(或Python库)?
I want to assign each of them scores (from 0 .. 1) indicating the likelihood that they are English sentences. Is there an accepted algorithm (or Python library) from which to do this?
注意:我不在乎英语句子的语法是否完美.
Note: I don't care if the grammar of the English sentence is perfect.
推荐答案贝叶斯分类器会是完成此任务的好选择:
A bayesian classifier would be a good choice for this task:
>>> from reverend.thomas import Bayes >>> g = Bayes() # guesser >>> g.train('french','La souris est rentrée dans son trou.') >>> g.train('english','my tailor is rich.') >>> g.train('french','Je ne sais pas si je viendrai demain.') >>> g.train('english','I do not plan to update my website soon.') >>> print g.guess('Jumping out of cliffs it not a good idea.') [('english', 0.99990000000000001), ('french', 9.9999999999988987e-005)] >>> print g.guess('Demain il fera très probablement chaud.') [('french', 0.99990000000000001), ('english', 9.9999999999988987e-005)]更多推荐
