我刚刚测试了 AlchemyAPI。它不是 100% 准确,但我猜这种技术仍处于起步阶段。
您需要注册(免费)才能获得 api 密钥。
这是一个示例用法:http://access.alchemyapi.com/calls/text/TextGetTextSentiment?apikey=<insert your api key>&sentiment=1&showSourceText=1&text=Kindle%20e-book%20sales%20soar%20for%20Amazon.%20Amazon.com%20says%20it%20is%20selling%20more%20e-books%20for%20its%20Kindle%20electronic%20reading%20device%20than%20paperback%20and%20hardback%20print%20editions%20combined
输入是:
- 情绪=1
- 显示源文本=1
- 文本(我使用了您的示例文本,uri 编码)
我得到以下输出(中性情绪,而不是预期的积极情绪):
