Turkish Deasciifier

This tool is used to turn Turkish text written in ASCII characters, which do not include some letters of the Turkish alphabet, into correctly written text with the appropriate Turkish characters (such as ı, ş, and so forth). It can also do the opposite, turning Turkish input into ASCII text, for the purpose of processing.

Requirements

• Xcode Editor
• Git

Git

Install the latest version of Git.

Download Code

In order to work on code, create a fork from GitHub page. Use Git for cloning the code to your local or below line for Ubuntu:

git clone <your-fork-git-link>

A directory called NGram-Swift will be created. Or you can use below link for exploring the code:

git clone https://github.com/starlangsoftware/TurkishDeasciifier-Swift.git

Open project with XCode

To import projects from Git with version control:

• XCode IDE, select Clone an Existing Project.

• In the Import window, paste github URL.

• Click Clone.

Result: The imported project is listed in the Project Explorer view and files are loaded.

Compile

From IDE

After being done with the downloading and opening project, select Build option from Product menu. After compilation process, user can run TurkishDeasciifier-Swift.

Detailed Description

• Asciifier
• Deasciifier

Using Asciifier

Asciifier converts text to a format containing only ASCII letters. This can be instantiated and used as follows:

  Asciifier asciifier = SimpleAsciifier()
  Sentence sentence = Sentence("çocuk"")
  Sentence asciified = asciifier.asciify(sentence)

Output:

cocuk      

Using Deasciifier

Deasciifier converts text written with only ASCII letters to its correct form using corresponding letters in Turkish alphabet. There are two types of Deasciifier:

• SimpleDeasciifier

  The instantiation can be done as follows:

    let fsm = FsmMorphologicalAnalyzer()
    let deasciifier = SimpleDeasciifier(fsm)
  

• NGramDeasciifier

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

  • FsmMorphologicalAnalyzer can be instantiated as follows:

      let fsm = FsmMorphologicalAnalyzer()
    

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

    • Training from scratch:

        let corpus = Corpus("corpus.txt"); 
        let ngram = NGram(corpus.getAllWordsAsArrayList(), 1)
        ngram.calculateNGramProbabilities(LaplaceSmoothing())
      

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

    • Loading from an existing model:

            let ngram = NGram("ngram.txt")
      

  For further details, please check here.

  • Afterwards, NGramDeasciifier can be created as below:

      let deasciifier = NGramDeasciifier(fsm, ngram)
    

A text can be deasciified as follows:

Sentence sentence = Sentence("cocuk")
Sentence deasciified = deasciifier.deasciify(sentence)

Output:

çocuk

For Contibutors

Package.swift file

1. Dependencies should be given w.r.t github.

    dependencies: [
        .package(name: "MorphologicalAnalysis", url: "https://github.com/StarlangSoftware/TurkishMorphologicalAnalysis-Swift.git", .exact("1.0.6"))],

2. Targets should include direct dependencies, files to be excluded, and all resources.

    targets: [
        .target(
	dependencies: ["MorphologicalAnalysis"],
	exclude: ["turkish1944_dictionary.txt", "turkish1944_wordnet.xml",
	"turkish1955_dictionary.txt", "turkish1955_wordnet.xml",
	"turkish1959_dictionary.txt", "turkish1959_wordnet.xml",
	"turkish1966_dictionary.txt", "turkish1966_wordnet.xml",
	"turkish1969_dictionary.txt", "turkish1969_wordnet.xml",
	"turkish1974_dictionary.txt", "turkish1974_wordnet.xml",
	"turkish1983_dictionary.txt", "turkish1983_wordnet.xml",
	"turkish1988_dictionary.txt", "turkish1988_wordnet.xml",
	"turkish1998_dictionary.txt", "turkish1998_wordnet.xml"],
	resources:
[.process("turkish_wordnet.xml"),.process("english_wordnet_version_31.xml"),.process("english_exception.xml")]),

3. Test targets should include test directory.

	.testTarget(
		name: "WordNetTests",
		dependencies: ["WordNet"]),

Data files

1. Add data files to the project folder.

Swift files

1. Do not forget to comment each function.

   /**
     * Returns the value to which the specified key is mapped.
     - Parameters:
        - id: String id of a key
     - Returns: value of the specified key
     */
    public func singleMap(id: String) -> String{
        return map[id]!
    }

2. Do not forget to define classes as open in order to be able to extend them in other packages.

	open class Word : Comparable, Equatable, Hashable

3. Function names should follow caml case.

	public func map(id: String)->String?

4. Write getter and setter methods.

	public func getSynSetId() -> String{
	public func setOrigin(origin: String){

5. Use separate test class extending XCTestCase for testing purposes.

final class WordNetTest: XCTestCase {
    var turkish : WordNet = WordNet()
    
    func testSize() {
        XCTAssertEqual(78326, turkish.size())
    }

6. Enumerated types should be declared as enum.

public enum CategoryType : String{
    case MATHEMATICS
    case SPORT
    case MUSIC

7. Implement == operator and hasher method for hashing purposes.

    public func hash(into hasher: inout Hasher) {
        hasher.combine(name)
    }
    public static func == (lhs: Relation, rhs: Relation) -> Bool {
        return lhs.name == rhs.name
    }

8. Make classes Comparable for comparison, Equatable for equality, and Hashable for hashing check.

	open class Word : Comparable, Equatable, Hashable

9. Implement < operator for comparison purposes.

    public static func < (lhs: Word, rhs: Word) -> Bool {
        return lhs.name < rhs.name
    }

10. Implement description for toString method.

	open func description() -> String{

11. Use Bundle and XMLParserDelegate for parsing Xml files.

	let url = Bundle.module.url(forResource: fileName, withExtension: "xml")
	var parser : XMLParser = XMLParser(contentsOf: url!)!
	parser.delegate = self
	parser.parse()

also use parser method.

public func parser(_ parser: XMLParser, didStartElement elementName: String, namespaceURI: String?, qualifiedName qName: String?, attributes attributeDict: [String : String])
