# spaCy Symspell ## Spelling correction implementation in spaCy via Symspell

This package is a [spaCy 2.0 extension](https://spacy.io/usage/processing-pipelines#section-extensions) that adds sentnece/spelling corrections via Symspell to spaCy’s text processing pipeline.

## Installation

pip install spacy_symspell

## Notes This package is still in Alpha and there may be unforeseen errors. Dictionary loading time is also significant, can take up to 30 seconds on slow machines.

## Usage

Adding the component to the processing pipeline is relatively simple:

import spacy from spacy_symspell import SpellingCorrector

nlp = spacy.load(‘en_core_web_sm’) corrector = SpellingCorrector() nlp.add_pipe(corrector) doc = nlp(‘What doyuoknowabout antyhing’)

for s in doc._.suggestions:#iterable

print(s) #What doyon about anything

doc._.segmentation #::segmented_string - What doyouk now about antyhing ::corrected_string - that dook now about anything

spaCy_symspell operates on Doc and Span spaCy objects. When called on a Doc or Span, the object is given two attributes: suggestions (a list of all found spelling suggestions) and segmentation (a corrected sentence in the case of ommitted spaces).

## Todo Symspell accuracy can be improved with the help of spaCy by extracting and analyzing resulting n-grams and cross-referencing with possible n-grams deductible from the character groups in the symspell result. For example the correction ‘that dook now’ leaves us with a verbless sentence, and on closer analysis will reveal that the character group ‘now’ is related with the verb ‘know’, and the verb know is associated with the n-gram ‘you know’.

## Under the hood [spacy_symspell](https://github.com/xwiz/spacy_symspell) is currently a wrapper of the [python port](https://github.com/mammothb/symspellpy) for [Symspell](https://github.com/wolfgarbe/SymSpell). For additional details, see the linked project pages.
