# FASpell Dataset

## Context
The FASpell dataset was developed to evaluate spell-checking algorithms. It consists of pairs of misspelled Persian (Farsi) words and their corresponding corrected forms, similar to the ASpell dataset used for English.

## Content
The dataset is divided into two parts:
1. **faspell_main**: A list of 5050 pairs collected from errors made by elementary school pupils and professional typists.
2. **faspell_ocr**: A list of 800 pairs collected from the output of a Farsi OCR system.

## Acknowledgements
The dataset is based on a work from [http://pars.ie/lr/FAspell_Dataset](http://pars.ie/lr/FAspell_Dataset). Please acknowledge the use of this dataset by referencing one of the following papers:

## Inspiration
The dataset can be used to explore various questions, including:
- Which kinds of misspellings occur more often?
- Are certain characters more likely to be misspelled? Certain words?
- Can you construct a finite state automaton spell checker for Persian based on this data?
