## Creating SpellChecker

SpellChecker finds spelling errors and corrects them in Turkish. There are two types of spell checker available:

* `SimpleSpellChecker`
    
    * To instantiate this, a `FsmMorphologicalAnalyzer` is needed. 
        
            fsm = FsmMorphologicalAnalyzer()
            spellChecker = SimpleSpellChecker(fsm)   
     
* `NGramSpellChecker`,
    
    * To create an instance of this, both a `FsmMorphologicalAnalyzer` and a `NGram` is required. 
    
    * `FsmMorphologicalAnalyzer` can be instantiated as follows:
        
            fsm = FsmMorphologicalAnalyzer()
    
    * `NGram` can be either trained from scratch or loaded from an existing model.
        
        * Training from scratch:
                
                corpus = Corpus("corpus.txt");
                ngram = NGram(corpus.getAllWordsAsArrayList(), 1)
                ngram.calculateNGramProbabilities(LaplaceSmoothing())
                
        *There are many smoothing methods available. For other smoothing methods, check [here](https://github.com/olcaytaner/NGram).*       
        * Loading from an existing model:
     
                ngram = NGram("ngram.txt")

	*For further details, please check [here](https://github.com/starlangsoftware/NGram).*        
            
    * Afterwards, `NGramSpellChecker` can be created as below:
        
            spellChecker = NGramSpellChecker(fsm, ngram)
     

## Spell Correction

Spell correction can be done as follows:

    sentence = Sentence("Dıktor olaç yazdı")
    corrected = spellChecker.spellCheck(sentence)
    print(corrected)
    
Output:

    Doktor ilaç yazdı
