WIP - Kotlin CLD3 - Google's Compact Language Detector 3

Bridge from c++ to Kotlin using Java Abstracted Foreign Function Layer

Operations Systems Support:

Job	OS	State	Shared Objects
47.1	macOS	passed	dylib
47.2	Linux	passed	so
-	windows	not supported	-

Usage Examples:

add maven dependencies

     <version>1.0.2</version>
</dependency>

download os shred objects and add them under src/lib/(os-name)

val ld = LangDetect()
val englishText = "This piece of text is in English";
var result = ld.detect(englishText)
assert(result.language == "English")
assert(result.isReliable)
assert(result.proportion == 1f)

val ld = LangDetect()
val englishBulgarianText = "This piece of text is in English Този текст е на Български";
val results = ld.findTopNMostFreqLangs(englishBulgarianText, 3)
val languages = results.map { it.language }
assert(languages.size == 3)
assert(languages.contains("English"))
assert(languages.contains("Bulgarian"))
assert(languages.contains("UNKNOWN"))

The Bridge Interface Implemantation:

from (C++)

std::vector<Result> FindTopNMostFreqLangs(const string &text, int num_langs);

Result FindLanguage(const string &text);

to (Kotlin)

fun findTopNMostFreqLangs(text: String, n: Int): List<LangDetectResponse> 

fun detect(text: String): LangDetectResponse 

data class LangDetectResponse(
    val probability: Float,
    val proportion: Float,
    val isReliable: Boolean,
    val language: String
)
