Demo

package main

import (
    "fmt"
    "github.com/lucasmenendez/gotokenizer"
    "github.com/lucasmenendez/gotagger"
)

func main() {
    var limit int = 15
    var lang string = "<input-lang>"
    var text string = "<input-text>"
    
    var words [][]string
    for _, s := range gotokenizer.Sentences(text) {
        words = append(words, gotokenizer.Words(s))
    }
    
    if tags, err := gotagger.GetTags(words, lang, limit); err != nil {
        fmt.Println(err)
    } else {
        fmt.Printf("%q\n", tags)
    }
