Detailed Description

• Spell Correction

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

For Contibutors

Resources

1. Add resources to the project directory. Do not forget to choose 'EmbeddedRecource' in 'Build Action' and 'Copy always' in 'Copy to output directory' in File Properties dialog.

C# files

1. Do not forget to comment each function.

	/**
	* <summary>Returns the first literal's name.</summary>
	*
	* <returns>the first literal's name.</returns>
	*/
	public string Representative()
	{
		return GetSynonym().GetLiteral(0).GetName();
	}

2. Function names should follow pascal caml case.

	public string GetLongDefinition()

3. Write ToString methods, if necessary.
4. Use var type as a standard type.

	public override bool Equals(object second)
	{
		var relation = (Relation) second;

5. Use standard naming for private and protected class variables. Use _ for private and capital for protected class members.

    public class SynSet
    {
        private string _id;
		protected string Name;

6. Use NUnit for writing test classes. Use test setup if necessary.

   public class WordNetTest
    {
        WordNet.WordNet turkish;

        [SetUp]
        public void Setup()
        {
            turkish = new WordNet.WordNet();
        }

        [Test]
        public void TestSynSetList()
        {
            var literalCount = 0;
            foreach (var synSet in turkish.SynSetList()){
                literalCount += synSet.GetSynonym().LiteralSize();
            }
            Assert.AreEqual(110259, literalCount);
        }
