Gender guesser written in Go

Inspired by the python gender guesser, with data from the program "gender" by Jorg Michael

Motivation

• Performance
• Only males or females
• In a go package

Usage

• Make sure you have your $GOPATH set, otherwise

$ export GOPATH=~/go # Or your gopath location

• Install

$ go get -u github.com/octohedron/gander

• Example

package main

import "log"
import "github.com/octohedron/gander"

func main() {
	g, err := gander.CheckGender("Aad")
	if err == nil {
		// prints 'm'
		log.Println(g.Gender)
	} else {
		// It would print 'Aad', if there was an error
		log.Println(g.Name)
    }
}

Performance

The fastest is to use the CheckGenderMap func, but it doesn't return an error, only "unknown" if it doesn't find the gender.

func TestBenchmark(t *testing.T) {
	var males int
	var females int
	const total = 100000000 // 100 million
	t.Log("START")
	for i := 0; i < total; i++ {
		g := CheckGenderMap(
			NGData[rand.Intn(len(NGData))].Name)
		if g == "f" {
			females++
		} else {
			males++
		}
	}
	t.Logf("In %d we found %d females and %d males", total, females, males)
}

2019/01/27 20:51:29.781984 In 100000000 we found 47278122 females and 52721878 males

That's ~ 7.7M/s 🔥🔥🔥

With error

func TestAllLoadedNames(t *testing.T) {
	var males int
	var females int
	c := make(chan int)
	var complete int
	for _, n := range NGData {
		go func(n NameGender) {
			g, err := CheckGender(n.Name)
			if err == nil {
				if g.Gender == "f" {
					c <- 1
				} else {
					c <- 0
				}
			}
		}(n)
	}
	for p := range c {
		complete++
		if p == 1 {
			females++
		} else {
			males++
		}
		if complete == len(NGData) {
			break
		}
	}
	log.Println("COMPLETED")
	t.Logf("In %d we found %d females and %d males", len(NGData), females, males)
}

Prints
