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.

      FsmMorphologicalAnalyzer fsm = new FsmMorphologicalAnalyzer();
      SpellChecker spellChecker = new SimpleSpellChecker(fsm);   
    

• NGramSpellChecker,

  • To create an instance of this, both a FsmMorphologicalAnalyzer and a NGram is required.

  • FsmMorphologicalAnalyzer can be instantiated as follows:

      FsmMorphologicalAnalyzer fsm = new FsmMorphologicalAnalyzer();
    

  • NGram can be either trained from scratch or loaded from an existing model.

    • Training from scratch:

        Corpus corpus = new Corpus("corpus.txt"); 
        NGram ngram = new NGram(corpus.GetAllWordsAsArrayList(), 1);
        ngram.CalculateNGramProbabilities(LaplaceSmoothing());
      

    There are many smoothing methods available. For other smoothing methods, check here.

    • Loading from an existing model:

        NGram ngram = new NGram("ngram.txt");
      

  For further details, please check here.

  • Afterwards, NGramSpellChecker can be created as below:

      SpellChecker spellChecker = new NGramSpellChecker(fsm, ngram);
    

Spell Correction

Spell correction can be done as follows:

Sentence sentence = new Sentence("Dıktor olaç yazdı");
Sentence corrected = spellChecker.SpellCheck(sentence);
Console.WriteLine(corrected);

Output:

Doktor ilaç yazdı
