SymSpell is a C# library implementing the Symmetric Delete spelling correction algorithm for extremely fast spelling correction and fuzzy string search. It also supports compound-aware correction and word segmentation, and is language independent.
Use cases
- correct spelling errors in user search queries
- fuzzy match strings against a dictionary at high speed
- segment concatenated text into words
- build autocorrect for a text editor
- check spelling of Chinese or other language text
- find closest dictionary match for OCR output
When to choose
- you need spelling correction orders of magnitude faster than Norvig-style approaches
- you need language-independent correction including CJK text
- you need compound-aware correction or word segmentation in .NET
When to avoid
- you need a full-featured search engine rather than a spelling component
- your project cannot use .NET and no port is available
- you need context-aware (grammar-based) correction rather than edit-distance lookup
