A spelling corrector for the Spanish language or create your own.

The solution for this project was based on the proposal made on the following website: http://norvig.com/spell-correct.html and some ideas from https://cxwangyi.wordpress.com/2012/02/15/peter-norvigs-spelling-corrector-in-go/ as well.

> The built-in data was trained using the `Spanish` language.

## Try it

Use it now with a Docker instance. It will open the `8080` port to access the service.

docker pull jorelosorio/spellingcorrector:latest

docker run --name spellingcorrector -d -p 8080:80 -t jorelosorio/spellingcorrector:latest

Try it using the following example:

http://localhost:8080/spelling?word=espanol

## Tools

- GoLang `1.17.x`
- Docker
- Visual Studio Code `Optional!`
> It requires a `Remote - Containers` extension. for more information please refers to: https://code.visualstudio.com/docs/remote/containers#_getting-started

## Development

This project contains a `Dockerfile` file with all required dependencies to run it using `Visual Studio Code` + `Remote - Containers` extension.
However, if you want to make it run locally in your development machine, please follow the instructions below.

### Install Go

Install it from https://go.dev/dl/

### Build the `Example/Service`

> Make sure the port `80` is currently free. **Optionally could be changed in the code!**

go build -o ./bin/ ./examples/service.go

Then run the service

./bin/service ./dictionaries/es.dic

### Example of correction

Simple usage example of the `Corrector` function.

```go
package main

import (
"fmt"

sc "github.com/jorelosorio/spellingcorrector"
)

func main() {
spelling, _ := sc.NewSpelling("{YOUR_PATH_TO_DICTIONARY}")
correctedWord := spelling.Correction("espanol")
fmt.Println(correctedWord)
}
```

> `NewSpelling` functions returns (`Spelling`, `error`), make sure to handle errors when creating a new object.

### Training

Most of the training was made using free versions of books in `Spanish`. However, if you like to train for a new language you can use the following functions

```go
package main

import (
sc "github.com/jorelosorio/spellingcorrector"
)

func main() {
dic, _ := sc.NewDictionary("{YOUR_PATH_TO_DICTIONARY}", sc.ESAlphabet) // Or ENAlphabet
dic.TrainFromTextFile("{YOUR_INPUT_TEXT}")
}
```

> Call `TrainFromTextFile` function as many times you wish with different inputs.

> `NewDictionary` functions returns (`Dictionary`, `error`), make sure to handle errors when creating a new dictionary.

### Build Docker

To build the docker image use `.dockers/Dockerfile.deploy` and the command

docker build -f Dockerfile.deploy -t jorelosorio/spellingcorrector:latest .

To run the docker image

docker run --name spellingcorrector -d -p 8080:80 -t jorelosorio/spellingcorrector:latest

Test the `spelling corrector` from the docker image

http://localhost:8080/spelling?word=espanol
