汇率换算自然语言理解功能JAVA DEMO

>>>>>>>>>>>>>>>>>>>>>>>> 欢迎转载 <<<<<<<<<<<<<<<<<<<<<<<<

本文原地址:http://blog.csdn.net/happycxz/article/details/73223916

基础资源及工具

1. eclipse + windowbuilder插件
2. jdk 1.7
3. 免费开放语义接口平台 olami.ai
4. 参考开源代码 https://github.com/codingmonster/olami-nlu-samples-java.

实现功能

通过java客户端界面，输入汇率换算相关句子，可以查到汇率和货币相关的结果。

界面展示

APP内预置部分支持的说法，可点击“换一句”切换。点击“理解”即发送对应文本到olami开放语义服务器。
左下角是olami开放语义服务器返回的语义结构，右下角是我用对应拿到的语义，找了一个免费的汇率接口，获取到对应的数据展示出来。

源代码简介

1. CurrencyTable.java

   汇率货币代码、名称、别名，对应国家或地区名称、别名管理。主要是对currencyTable.csv配置文件中的配置数据解析。

olami平台NLI接口使用说明

1. 注册
2. 绑定手机
3. 登录

4. 选“自然语言语义互动系统”中的“进入NLI系统”
   NLI系统中，可以自己做语义模块，也可以导入已经有的语义模块。自己做语义模块相当于自己参与定制句型说法，刚接触这个，对规则不熟悉，暂时不考虑了。有兴趣的朋友可以尝试自己做语义模块。

5. 导入exchangerate语义模块

   这里用的汇率换算语义就是导入现成的exchangerate这个模块。

   附：olami已有模块介绍, 前面链接失效可以访问olami官网.

6. 进入刚刚导入的这个模块，点“发布”

   进入该模块后，能看到对应的语法信息，不需要关心，直接点“发布”，会显示“待发布的grammar（共xx个）： ” .

7. 发布完成后，回到原来登录账号后的首页面
8. 点击“创建新应用”，应用名称、应用类型、应用描述可以简单填一下。

9. 配置该应用

   在刚刚创建的应用中，要先配置一下第5步和第6步导入的语义模块。
   在“配置模块”页面中，有“NLI模块”和“对话系统模块”。
   “NLI模块”是我们要配置的那种语义模块，勾选上刚刚那个exchangerate模块的名称，后面的优先级保持为默认值不需要修改，然后点“确定”。
   “对话系统模块”是另一种模式的模块，直接返回的是处理结果，而不是NLI模块里的那种语义，这里暂不深入研究，感兴趣的朋友可以配置一下试试，尝尝鲜。

10. 测试

    配置完应用后，就可以用这个应用后面的“测试”去试验一下配置的是否生效。点开“测试”后，输入一句话“1美元等于多少人民币”，正常返回NLI语义，证明配置成功。

11. 获取应用对应的API访问密钥

    在“我的应用”中，找到之前生成的那个应用，点击“查看Key”可以获取调用OLAMI开放语义平台的授权密钥，包括“App Key”和“App Secret”。
    这两个码，对应我写的demo小程序中的“NLI.java”中的“Appkey”和“Appsecret”。

写在最后

开放语义跟语音产品结合效果更好，如果有机会，我会将这个APP做成对接语音识别的，这样只需要对着话筒说话就可以，不用输入文字了。
