## 使用

|
||
"fmt"
|
||
|
||
"github.com/go-ego/gse"
|
||
)
|
||
|
||
func main() {
|
||
// 载入词典
|
||
var seg gse.Segmenter
|
||
// 加载默认字典
|
||
seg.LoadDict()
|
||
// seg.LoadDict("your gopath"+"/src/github.com/go-ego/gse/data/dict/dictionary.txt")
|
||
|
||
// 分词
|
||
text := []byte("中华人民共和国中央人民政府")
|
||
fmt.Println(seg.String(text, true))
|
||
|
||
segments := seg.Segment(text)
|
||
|
||
// 处理分词结果
|
||
// 支持普通模式和搜索模式两种分词，见代码中 ToString 函数的注释。
|
||
// 搜索模式主要用于给搜索引擎提供尽可能多的关键字
|
||
fmt.Println(gse.ToString(segments))
|
||
|
||
text1 := []byte("深圳地标建筑, 深圳地王大厦")
|
||
segments1 := seg.Segment([]byte(text1))
|
||
fmt.Println(gse.ToString(segments1, true))
|
||
}

```
