介绍

CustomerService是一个可以从句子里面拆出词汇,并且可以实现问题和回答的相似度匹配的AI系统. 理论上只要词库(中文已有部分)和问答库(未导入)足够的大,就可以实现非常完美的问答.Power By NodeJs.

要求

由于使用了async和await,所以nodejs版本要在7.7.1以上.或使用babel.

安装

npm install customer-service

使用

初始化工具

const CustomerService = require("customer-service");
var customerService = new CustomerService('mylang',2,13);
var sw = customerService.getSplitWord();
var ie = customerService.getImportExport();
var qa = customerService.getQuestionAnswer();

拆词

sw.collisionWord(sw.sentenceToList('我在洗澡，你在干嘛'))
.then((res)=>{
console.log(res);
/* will print
[ { key: 'word:b7669c4218782c0035b6383623e19b29',
    word: '我在',
    questionList: {} },
  { key: 'word:5ac500cfcc1fe66f7243cad4039281d1',
    word: '洗澡',
    questionList: {} },
  { key: 'word:9d63b7094c5a502e66fccc79e5fe1f69',
    word: '你在',
    questionList: {} },
  { key: 'word:c44a42f209fa03606e607994c2321ebd',
    word: '干嘛',
    questionList: {} } ]
*/
});

库的导入和打印

//导入词库字符串
var chunk = "你好\r\n智能";
ie.stringToLevel(chunk,'word')
.then((res)=>{
	console.log(res);
})
.catch((err)=>{
	console.log(err);
});

//导入问答字符串
var chunk = "你在洗澡吗？===>>>然而并没有.\r\n你是屌丝吗？===>>>不是屌丝写什么代码.";
ie.stringToLevel(chunk,'word')
.then((res)=>{
	console.log(res);
})
.catch((err)=>{
	console.log(err);
});

//导入问答字符串

const path = require('path');
//导入词库
ie.readWordToLevel(path.join(__dirname,'word.log'),'word')
.then((res)=>{
	console.log(res);
})
.catch((err)=>{
	console.log(err);
});
//导入问答
ie.readWordToLevel(path.join(__dirname,'qa.log'),'qa')
.then((res)=>{
	console.log(res);
})
.catch((err)=>{
	console.log(err);
});
//print data
ie.printData({start:'word',limit:10});

获取回答

//获取最佳回答
qa.getAnswer('你是屌丝吗')
.then((res)=>{
	console.log(res);
})
.catch((err)=>{
	console.log(err);
});

intro

CustomerService is a down words from a sentence, and can realize question and answer the similarity matching of AI system. Theoretically as long as the word library (Chinese existing part) and q&a library (import) not enough big, can achieve very perfect answers. The Power By NodeJs.

req

nodejs'version>7.7.1 or use babel.

install

npm install customer-service

init

const CustomerService = require("customer-service");
var customerService = new CustomerService('mylang',2,13);

Additionally, you can supply an options object as the first parameter to createReadStream() with the following options:

• 'gt' (greater than), 'gte' (greater than or equal) define the lower bound of the range to be streamed. Only records where the key is greater than (or equal to) this option will be included in the range. When reverse=true the order will be reversed, but the records streamed will be the same.

• 'lt' (less than), 'lte' (less than or equal) define the higher bound of the range to be streamed. Only key/value pairs where the key is less than (or equal to) this option will be included in the range. When reverse=true the order will be reversed, but the records streamed will be the same.

• 'start', 'end' legacy ranges - instead use 'gte', 'lte'

• 'reverse' (boolean, default: false): a boolean, set true and the stream output will be reversed. Beware that due to the way LevelDB works, a reverse seek will be slower than a forward seek.

• 'keys' (boolean, default: true): whether the 'data' event should contain keys. If set to true and 'values' set to false then 'data' events will simply be keys, rather than objects with a 'key' property. Used internally by the createKeyStream() method.

• 'values' (boolean, default: true): whether the 'data' event should contain values. If set to true and 'keys' set to false then 'data' events will simply be values, rather than objects with a 'value' property. Used internally by the createValueStream() method.

• 'limit' (number, default: -1): limit the number of results collected by this stream. This number represents a maximum number of results and may not be reached if you get to the end of the data first. A value of -1 means there is no limit. When reverse=true the highest keys will be returned instead of the lowest keys.

• 'fillCache' (boolean, default: false): whether LevelDB's LRU-cache should be filled with data read.

• 'keyEncoding' / 'valueEncoding' (string): the encoding applied to each read piece of data.
