GoJieba是"结巴"中文分词的Golang语言版本。

简介

  • 支持多种分词方式,包括: 最大概率模式, HMM新词发现模式, 搜索引擎模式, 全模式
  • 核心算法底层由C++实现,性能高效。
  • 字典路径可配置,NewJieba(...string), NewExtractor(...string) 可变形参,当参数为空时使用默认词典(推荐方式)

用法

go get github.com/yanyiwu/gojieba

分词示例

package main

import (
    "fmt"
    "strings"

    "github.com/yanyiwu/gojieba"
)

func main() {
    var s string
    var words []string
    use_hmm := true
    x := gojieba.NewJieba()
    defer x.Free()

    s = "我来到北京清华大学"
    words = x.CutAll(s)
    fmt.Println(s)
    fmt.Println("全模式:", strings.Join(words, "/"))

    words = x.Cut(s, use_hmm)
    fmt.Println(s)
    fmt.Println("精确模式:", strings.Join(words, "/"))
    s = "比特币"
    words = x.Cut(s, use_hmm)
    fmt.Println(s)
    fmt.Println("精确模式:", strings.Join(words, "/"))

    x.AddWord("比特币")
    s = "比特币"
    words = x.Cut(s, use_hmm)
    fmt.Println(s)
    fmt.Println("添加词典后,精确模式:", strings.Join(words, "/"))

    s = "他来到了网易杭研大厦"
    words = x.Cut(s, use_hmm)
    fmt.Println(s)
    fmt.Println("新词识别:", strings.Join(words, "/"))

    s = "小明硕士毕业于中国科学院计算所,后在日本京都大学深造"
    words = x.CutForSearch(s, use_hmm)
    fmt.Println(s)
    fmt.Println("搜索引擎模式:", strings.Join(words, "/"))

    s = "长春市长春药店"
    words = x.Tag(s)
    fmt.Println(s)
    fmt.Println("词性标注:", strings.Join(words, ","))

    s = "区块链"
    words = x.Tag(s)
    fmt.Println(s)
    fmt.Println("词性标注:", strings.Join(words, ","))

    s = "长江大桥"
    words = x.CutForSearch(s, !use_hmm)
    fmt.Println(s)
    fmt.Println("搜索引擎模式:", strings.Join(words, "/"))

    wordinfos := x.Tokenize(s, gojieba.SearchMode, !use_hmm)
    fmt.Println(s)
    fmt.Println("Tokenize:(搜索引擎模式)", wordinfos)

    wordinfos = x.Tokenize(s, gojieba.DefaultMode, !use_hmm)
    fmt.Println(s)
    fmt.Println("Tokenize:(默认模式)", wordinfos)

    keywords := x.ExtractWithWeight(s, 5)
    fmt.Println("Extract:", keywords)
}
