Go efficient multilingual NLP and text segmentation; support english, chinese, japanese and other. And supports with elasticsearch and bleve.
Gse is implements jieba by golang, and try add NLP support and more feature
gse-bind, binding JavaScript and other, support more language.
go get -u github.com/go-ego/gse

Look at an custom dictionary example
package main
import (
"fmt"
_ "embed"
"github.com/go-ego/gse"
)
//go:embed test_dict3.txt
var testDict string
func main() {
// var seg gse.Segmenter
// seg.LoadDict("zh, testdata/test_dict.txt, testdata/test_dict1.txt")
// seg.LoadStop()
seg, err := gse.NewEmbed("zh, word 20 n"+testDict, "en")
// seg.LoadDictEmbed()
seg.LoadStopEmbed()
text1 := "你好世界, Hello world"
fmt.Println(seg.Cut(text1, true))
fmt.Println(seg.String(text1, true))
segments := seg.Segment([]byte(text1))
fmt.Println(gse.ToString(segments))
}
How to use it with elasticsearch?
go get -u github.com/go-ego/re
To create a new gse application
$ re gse my-gse
To run the application we just created, you can navigate to the application folder and execute:
$ cd my-gse && re run
