Python version has different result: "旅游", "游历"

[wcchh]

As title. I got 0.17365640608647942 from below :

var synonyms = require("node-synonyms");
synonyms.compare("旅游", "游历") 
	.then(function (similarity) {
		console.log(similarity);
	});

But as Synonyms (Python) has value: 0.872 for this pair. print("旅游, 游历: %s" % (synonyms.compare("旅游", "游历")))

Please let me know how to correct it, thanks in advance.
