[![Go Report Card](https://goreportcard.com/badge/github.com/mb-14/gomarkov)](https://goreportcard.com/report/github.com/mb-14/gomarkov)

Go implementation of markov chains for textual data.

You can find out more about markov chains [here](http://setosa.io/ev/markov-chains/) and [here](https://towardsdatascience.com/introduction-to-markov-chains-50da3645a50d)

## Usage

```go

package main

import (

	"github.com/mb-14/gomarkov"

	"fmt"

	"strings"

	"io/ioutil"

	"encoding/json"

)

func main() {

	//Create a chain of order 2

	chain := gomarkov.NewChain(2)

	//Feed in training data

	chain.Add(strings.Split("I want a cheese burger", " "))

	chain.Add(strings.Split("I want a chilled sprite", " "))

	chain.Add(strings.Split("I want to go to the movies", " "))

	//Get transition probability of a sequence

	prob, _ := chain.TransitionProbability("a", []string{"I", "want"})

	fmt.Println(prob)

	//Output: 0.6666666666666666

	//You can even generate new text based on an initial seed

	chain.Add(strings.Split("Mother should I build the wall?", " "))

	chain.Add(strings.Split("Mother should I run for President?", " "))

	chain.Add(strings.Split("Mother should I trust the government?", " "))

	next, _ := chain.Generate([]string{"should", "I"})

	fmt.Println(next)

	//The chain is JSON serializable

	jsonObj, _ := json.Marshal(chain)

	err := ioutil.WriteFile("model.json", jsonObj, 0644)

	if err != nil {

		fmt.Println(err)

	}

}

```
