Golang : Example of how to detect which type of script a word belongs to
In one of my projects, I need to detect if a word that cannot be translated is of Arabic or Latin script type. In order to detect a word's script type, I use the unicode.In()
function to match every single character inside the word against a dictionary.
Golang's unicode
package provides the dictionary that I needed and it is fairly easy to do so with a for loop.
Here you go!
package main
import (
"fmt"
"github.com/chrisport/go-lang-detector/langdet/langdetdef"
"unicode"
)
func main() {
// "love" translated to different languages
input := []string{"爱", "好き", "ආදරය", "cinta", "حب", "مينه", "ฮัก", "माया"}
for k, v := range input {
if checkifLatin(v) {
fmt.Println(k, "["+v+"] is a Latin or a derivative of Latin ? ", checkifLatin(v))
} else if checkifArabic(v) {
fmt.Println(k, "["+v+"] is an Arabic or a derivative of Arabic ? ", checkifArabic(v))
} else if checkifThai(v) {
fmt.Println(k, "["+v+"] is a Thai or a derivative of Thai ? ", checkifThai(v))
} else if checkifHan(v) {
fmt.Println(k, "["+v+"] is a Han(Chinese) or a derivative of Han(Chinese) ? ", checkifHan(v))
} else if checkifDevanagari(v) {
fmt.Println(k, "["+v+"] is a Devanagari or a derivative of Devanagari ? ", checkifDevanagari(v))
} else {
// throw in an unknown script Japanese and Sinhala just to test out. To detect, use unicode.Sinhala and unicode.Hiragana
fmt.Println(k, "["+v+"] unable to detect script type. Need new function to detect this script type. ")
}
}
fmt.Println("----------------------------------------------------------------------------")
// alternative method, but....it is not what I want.
detector := langdetdef.NewWithDefaultLanguages()
result := detector.GetClosestLanguage(input[4])
fmt.Println("GetClosestLanguage returns : ", result)
}
// checkifLatin - check if input is Latin scripts or not.
func checkifLatin(input string) bool {
var isLatin = false
for _, v := range input {
if unicode.In(v, unicode.Latin) {
isLatin = true
} else {
isLatin = false
}
}
return isLatin
}
// checkifThai - check if input is Thai scripts or not.
func checkifThai(input string) bool {
var isThai = false
for _, v := range input {
if unicode.In(v, unicode.Thai) {
isThai = true
} else {
isThai = false
}
}
return isThai
}
// checkifArabic is Arabic characters or not.
func checkifArabic(input string) bool {
var isArabic = false
for _, v := range input {
if unicode.In(v, unicode.Arabic) {
isArabic = true
} else {
isArabic = false
}
}
return isArabic
}
// checkifHan is Han(Chinese) characters or not.
func checkifHan(input string) bool {
var isHan = false
for _, v := range input {
if unicode.In(v, unicode.Han) {
isHan = true
} else {
isHan = false
}
}
return isHan
}
// checkifDevanagari - check if input is Devanagari scripts or not.
func checkifDevanagari(input string) bool {
var isDevanagari = false
for _, v := range input {
if unicode.In(v, unicode.Devanagari) {
isDevanagari = true
} else {
isDevanagari = false
}
}
return isDevanagari
}
Output:
0 [爱] is a Han(Chinese) or a derivative of Han(Chinese) ? true
1 [好き] unable to detect script type. Need new function to detect this script type.
2 [ආදරය] unable to detect script type. Need new function to detect this script type.
3 [cinta] is a Latin or a derivative of Latin ? true
4 [حب] is an Arabic or a derivative of Arabic ? true
5 [مينه] is an Arabic or a derivative of Arabic ? true
6 [ฮัก] is a Thai or a derivative of Thai ? true
7 [माया] is a Devanagari or a derivative of Devanagari ? true
