Python Overtakes JavaScript as Top Programming Language on GitHub
Python becomes GitHub's top language in 2024, driven by AI and data science projects, while AI-powered security tools are gaining adoption.
NodeJieba
是"结巴"中文分词的 Node.js 版本实现,
由CppJieba提供底层分词算法实现,
是兼具高性能和易用性两者的 Node.js 中文分词组件。
对实现细节感兴趣的请看如下博文:
npm install nodejieba
因为npm
速度很慢而且经常因为墙的原因出现莫名其妙的问题,可以试试使用cnpm,命令如下:
npm --registry=http://r.cnpmjs.org install nodejieba
var nodejieba = require("nodejieba");
var result = nodejieba.cut("南京市长江大桥");
console.log(result);
//["南京市","长江大桥"]
更详细的其他用法请看 test/demo.js
如果没有主动调用词典函数时, 则会在第一次调用cut等功能函数时,自动载入默认词典。
如果要主动触发词典载入,则使用以下函数主动触发。
nodejieba.load();
以上用法会自动载入所有默认词典, 如果需要载入自己的词典,而不是默认词典。 比如想要载入自己的用户词典,则使用以下函数:
nodejieba.load({
userDict: './test/testdata/userdict.utf8',
});
字典载入函数load的参数项都是可选的, 如果没有对应的项则自动填充默认参数。 所以上面这段代码和下面这代代码是等价的。
nodejieba.load({
dict: nodejieba.DEFAULT_DICT,
hmmDict: nodejieba.DEFAULT_HMM_DICT,
userDict: './test/testdata/userdict.utf8',
idfDict: nodejieba.DEFAULT_IDF_DICT,
stopWordDict: nodejieba.DEFAULT_STOP_WORD_DICT,
});
【词典说明】
var nodejieba = require("nodejieba");
console.log(nodejieba.tag("红掌拨清波"));
//[ { word: '红掌', tag: 'n' },
// { word: '拨', tag: 'v' },
// { word: '清波', tag: 'n' } ]
更详细的其他用法请看 test/demo.js
var nodejieba = require("nodejieba");
var topN = 4;
console.log(nodejieba.extract("升职加薪,当上CEO,走上人生巅峰。", topN));
//[ { word: 'CEO', weight: 11.739204307083542 },
// { word: '升职', weight: 10.8561552143 },
// { word: '加薪', weight: 10.642581114 },
// { word: '巅峰', weight: 9.49395840471 } ]
更详细的其他用法请看 test/demo.js
以下版本中测试通过:
node v0.10.2
node v0.12.1
iojs v1.3.0
iojs v2.2.1
node v4.0.0
node v5.7.0
性能杠杠的,应该是目前性能最好的 Node.js 中文分词库,没有之一。 详见: Jieba中文分词系列性能评测
