简体中文

Dictionary with double array trie (Double-Array Trie) to achieve, Sender algorithm is the shortest path based on word frequency plus dynamic programming, and DAG and HMM algorithm word segmentation.

Support common, search engine, full mode, precise mode and HMM mode multiple word segmentation modes, support user dictionary, POS tagging, run JSON RPC service.

Support HMM cut text use Viterbi algorithm.

Text Segmentation speed single thread 9.2MB/s,goroutines concurrent 26.8MB/s. HMM text segmentation single thread 3.2MB/s. (2core 4threads Macbook Pro).

Binding:

gse-bind, binding JavaScript and other, support more language.

Install / update

go get -u github.com/go-ego/gse

Build-tools

go get -u github.com/go-ego/re

re gse

To create a new gse application

$ re gse my-gse

re run

To run the application we just created, you can navigate to the application folder and execute:

$ cd my-gse && re run

Use

package main

import (
    "fmt"

    "github.com/go-ego/gse"
)

var (
    text = "你好世界, Hello world."

    seg gse.Segmenter
)

func cut() {
    hmm := seg.Cut(text, true)
    fmt.Println("cut use hmm: ", hmm)

    hmm = seg.CutSearch(text, true)
    fmt.Println("cut search use hmm: ", hmm)

    hmm = seg.CutAll(text)
    fmt.Println("cut all: ", hmm)
}

func segCut() {
    // Text Segmentation
    tb := []byte(text)
    fmt.Println(seg.String(tb, true))

    segments := seg.Segment(tb)

    // Handle word segmentation results
    // Support for normal mode and search mode two participle,
    // see the comments in the code ToString function.
    // The search mode is mainly used to provide search engines
    // with as many keywords as possible
    fmt.Println(gse.ToString(segments, true))
}

func main() {
    // Loading the default dictionary
    seg.LoadDict()
    // Load the dictionary
    // seg.LoadDict("your gopath"+"/src/github.com/go-ego/gse/data/dict/dictionary.txt")

    cut()

    segCut()
}

Look at an custom dictionary example

package main

import (
    "fmt"

    "github.com/go-ego/gse"
)

func main() {
    var seg gse.Segmenter
    seg.LoadDict("zh,testdata/test_dict.txt,testdata/test_dict1.txt")

    text1 := []byte("你好世界, Hello world")
    fmt.Println(seg.String(text1, true))

    segments := seg.Segment(text1)
    fmt.Println(gse.ToString(segments))
}

Look at an Chinese example

Look at an Japanese example
