Anda dapat menggunakan ML Kit untuk mengidentifikasi bahasa pada suatu string teks. Anda dapat
mendapatkan bahasa {i>string<i} yang paling mungkin serta skor keyakinan untuk semua
kemungkinan bahasa {i>string<i}.
ML Kit mengenali teks di lebih dari 100 bahasa berbeda dalam skrip aslinya.
Selain itu, teks berbasis aksara romawi dapat dikenali untuk bahasa Arab, Bulgaria, China,
Yunani, Hindi, Jepang, dan Rusia. Lihat
daftar lengkap bahasa dan skrip yang didukung.

Sebelum memulai
Sertakan pod ML Kit berikut di Podfile Anda:
pod 'GoogleMLKit/LanguageID', '8.0.0'
Setelah Anda menginstal atau mengupdate Pod project, buka project Xcode menggunakan
.xcworkspace. ML Kit didukung di Xcode versi 12.4 atau yang lebih baru.
Mengidentifikasi bahasa string
Untuk mengidentifikasi bahasa string, dapatkan instance
LanguageIdentification, lalu teruskan string ke
Metode identifyLanguage(for:).
Contoh:
Swift
letlanguageId=NaturalLanguage.languageIdentification()languageId.identifyLanguage(for:text){(languageCode,error)inifleterror=error{print("Failed with error: \(error)")return}ifletlanguageCode=languageCode,languageCode!="und"{print("Identified Language: \(languageCode)")}else{print("No language was identified")}}
Objective-C
MLKLanguageIdentification*languageId=[MLKLanguageIdentificationlanguageIdentification];[languageIdidentifyLanguageForText:textcompletion:^(NSString*_NullablelanguageCode,NSError*_Nullableerror){if(error!=nil){NSLog(@"Failed with error: %@",error.localizedDescription);return;}if(![languageCodeisEqualToString:@"und"]){NSLog(@"Identified Language: %@",languageCode);}else{NSLog(@"No language was identified");}}];
Jika panggilan berhasil,
Kode bahasa BCP-47 adalah
diteruskan ke pengendali penyelesaian, menunjukkan bahasa teks. Jika tidak
bahasa dapat dideteksi dengan yakin, kode und (tidak ditentukan) diteruskan.
Secara default, ML Kit menampilkan nilai non-und hanya jika
bahasa dengan tingkat kepercayaan minimal 0,5. Anda dapat mengubah nilai minimum ini
dengan meneruskan objek LanguageIdentificationOptions ke
languageIdentification(options:):
Untuk mendapatkan nilai keyakinan dari bahasa string yang paling mungkin, dapatkan
instance LanguageIdentification, lalu teruskan string ke
Metode identifyPossibleLanguages(for:).
Contoh:
Swift
letlanguageId=NaturalLanguage.languageIdentification()languageId.identifyPossibleLanguages(for:text){(identifiedLanguages,error)inifleterror=error{print("Failed with error: \(error)")return}guardletidentifiedLanguages=identifiedLanguages,!identifiedLanguages.isEmpty,identifiedLanguages[0].languageCode!="und"else{print("No language was identified")return}print("Identified Languages:\n"+identifiedLanguages.map{String(format:"(%@, %.2f)",$0.languageCode,$0.confidence)}.joined(separator:"\n"))}
Objective-C
MLKLanguageIdentification*languageId=[MLKLanguageIdentificationlanguageIdentification];[languageIdidentifyPossibleLanguagesForText:textcompletion:^(NSArray*_NonnullidentifiedLanguages,NSError*_Nullableerror){if(error!=nil){NSLog(@"Failed with error: %@",error.localizedDescription);return;}if(identifiedLanguages.count==1&&[identifiedLanguages[0].languageCodeisEqualToString:@"und"]){NSLog(@"No language was identified");return;}NSMutableString*outputText=[NSMutableStringstringWithFormat:@"Identified Languages:"];for(MLKIdentifiedLanguage*languageinidentifiedLanguages){[outputTextappendFormat:@"\n(%@, %.2f)",language.languageCode,language.confidence];}NSLog(outputText);}];
Jika panggilan berhasil, daftar objek IdentifiedLanguage akan diteruskan ke
pengendali kelanjutan. Dari setiap objek, Anda bisa mendapatkan kode BCP-47 bahasa
dan keyakinan bahwa string ditulis dalam bahasa tersebut. Perlu diketahui bahwa
nilai ini menunjukkan keyakinan bahwa seluruh {i>string<i} dalam tabel yang diberikan
bahasa; ML Kit tidak mengidentifikasi banyak bahasa dalam satu string.
Secara default, ML Kit hanya menampilkan bahasa dengan tingkat keyakinan minimal
0,01. Anda dapat mengubah ambang batas ini dengan meneruskan
LanguageIdentificationOptions ke languageIdentification(options:):

Include the following ML Kit pods in your Podfile: \n\n ```\n pod 'GoogleMLKit/LanguageID', '8.0.0'\n ```\n2. After you install or update your project's Pods, open your Xcode project using its `.xcworkspace`. ML Kit is supported in Xcode version 12.4 or greater.\n\nIdentify the language of a string\n\nTo identify the language of a string, get an instance of\n`LanguageIdentification`, and then pass the string to the\n`identifyLanguage(for:)` method.\n\nFor example: \n\nSwift \n\n```swift\nlet languageId = NaturalLanguage.languageIdentification()\n\nlanguageId.identifyLanguage(for: text) { (languageCode, error) in\n if let error = error {\n print(\"Failed with error: \\(error)\")\n return\n }\n if let languageCode = languageCode, languageCode != \"und\" {\n print(\"Identified Language: \\(languageCode)\")\n } else {\n print(\"No language was identified\")\n }\n}\n```\n\nObjective-C \n\n```objective-c\nMLKLanguageIdentification *languageId = [MLKLanguageIdentification languageIdentification];\n\n[languageId identifyLanguageForText:text\n completion:^(NSString * _Nullable languageCode,\n NSError * _Nullable error) {\n if (error != nil) {\n NSLog(@\"Failed with error: %@\", error.localizedDescription);\n return;\n }\n if (![languageCode isEqualToString:@\"und\"] ) {\n NSLog(@\"Identified Language: %@\", languageCode);\n } else {\n NSLog(@\"No language was identified\");\n }\n }];\n```\n\nIf the call succeeds, a\n[BCP-47 language code](//en.wikipedia.org/wiki/IETF_language_tag) is\npassed to the completion handler, indicating the language of the text. If no\nlanguage could be confidently detected, the code `und` (undetermined) is passed.\n\nBy default, ML Kit returns a non-`und` value only when it identifies the\nlanguage with a confidence value of at least 0.5. You can change this threshold\nby passing a `LanguageIdentificationOptions` object to\n`languageIdentification(options:)`: \n\nSwift \n\n```swift\nlet options = LanguageIdentificationOptions(confidenceThreshold: 0.4)\nlet languageId = NaturalLanguage.languageIdentification(options: options)\n```\n\nObjective-C \n\n```objective-c\nMLKLanguageIdentificationOptions *options =\n [[MLKLanguageIdentificationOptions alloc] initWithConfidenceThreshold:0.4];\nMLKLanguageIdentification *languageId =\n [MLKLanguageIdentification languageIdentificationWithOptions:options];\n```\n\nGet the possible languages of a string\n\nTo get the confidence values of a string's most likely languages, get an\ninstance of `LanguageIdentification` and then pass the string to the\n`identifyPossibleLanguages(for:)` method.\n\nFor example: \n\nSwift \n\n```swift\nlet languageId = NaturalLanguage.languageIdentification()\n\nlanguageId.identifyPossibleLanguages(for: text) { (identifiedLanguages, error) in\n if let error = error {\n print(\"Failed with error: \\(error)\")\n return\n }\n guard let identifiedLanguages = identifiedLanguages,\n !identifiedLanguages.isEmpty,\n identifiedLanguages[0].languageCode != \"und\"\n else {\n print(\"No language was identified\")\n return\n }\n\n print(\"Identified Languages:\\n\" +\n identifiedLanguages.map {\n String(format: \"(%@, %.2f)\", $0.languageCode, $0.confidence)\n }.joined(separator: \"\\n\"))\n}\n```\n\nObjective-C \n\n```objective-c\nMLKLanguageIdentification *languageId = [MLKLanguageIdentification languageIdentification];\n\n[languageId identifyPossibleLanguagesForText:text\n completion:^(NSArray * _Nonnull identifiedLanguages,\n NSError * _Nullable error) {\n if (error != nil) {\n NSLog(@\"Failed with error: %@\", error.localizedDescription);\n return;\n }\n if (identifiedLanguages.count == 1\n && [identifiedLanguages[0].languageCode isEqualToString:@\"und\"] ) {\n NSLog(@\"No language was identified\");\n return;\n }\n NSMutableString *outputText = [NSMutableString stringWithFormat:@\"Identified Languages:\"];\n for (MLKIdentifiedLanguage *language in identifiedLanguages) {\n [outputText appendFormat:@\"\\n(%@, %.2f)\", language.languageCode, language.confidence];\n }\n NSLog(outputText);\n}];\n```\n\nIf the call succeeds, a list of `IdentifiedLanguage` objects is passed to the\ncontinuation handler. From each object, you can get the language's BCP-47 code\nand the confidence that the string is in that language. Note that\nthese values indicate the confidence that the entire string is in the given\nlanguage; ML Kit doesn't identify multiple languages in a single string.\n\nBy default, ML Kit returns only languages with confidence values of at least\n0.01. You can change this threshold by passing a\n`LanguageIdentificationOptions` object to `languageIdentification(options:)`: \n\nSwift \n\n```swift\nlet options = LanguageIdentificationOptions(confidenceThreshold: 0.4)\nlet languageId = NaturalLanguage.languageIdentification(options: options)\n```\n\nObjective-C \n\n```objective-c\nMLKLanguageIdentificationOptions *options =\n [[MLKLanguageIdentificationOptions alloc] initWithConfidenceThreshold:0.4];\nMLKLanguageIdentification *languageId =\n [MLKLanguageIdentification languageIdentificationWithOptions:options];\n```\n\nIf no language meets this threshold, the list has one item, with the value\n`und`."]]
