|
## 使用示例
|
|
|
|
|
|
|
|
下面是一个简单的示例,展示了如何使用 flashtext 进行关键词提取:
|
|
|
|
|
|
|
|
```go
|
|
|
|
import (
|
|
|
|
"git.echol.cn/loser/keyword-extraction"
|
|
|
|
"fmt"
|
|
|
|
)
|
|
|
|
|
|
|
|
func main() {
|
|
|
|
// 创建一个关键词处理器,不区分大小写
|
|
|
|
kp := extractor.NewKeywordProcessor(false)
|
|
|
|
|
|
|
|
// 添加关键词
|
|
|
|
kp.AddKeyword("apple")
|
|
|
|
kp.AddKeyword("banana")
|
|
|
|
kp.AddKeyword("orange")
|
|
|
|
|
|
|
|
// 提取关键词
|
|
|
|
sentence := "I have an Apple and a Banana."
|
|
|
|
matches := kp.ExtractKeywords(sentence)
|
|
|
|
|
|
|
|
// 打印匹配结果
|
|
|
|
for _, match := range matches {
|
|
|
|
fmt.Println("Match:", match.Match)
|
|
|
|
fmt.Println("Start:", match.Start)
|
|
|
|
fmt.Println("End:", match.End)
|
|
|
|
fmt.Println("---")
|
|
|
|
}
|
|
|
|
}
|
|
|
|
```
|
|
|
|
|
|
|
|
输出:
