我正在尝试使用日语的自然语言标注器。我使用了这个示例代码：“https://developer.apple.com/documentation/naturallanguage/identifying_people_places_and_organizations”，但它不识别个人或组织的名称。谁来帮帮我！谢谢

let text = "中村千恵子はトヨタ株式会社の社員です。"

let tagger = NLTagger(tagSchemes: [.nameType])
tagger.string = text

let options: NLTagger.Options = [.omitPunctuation, .omitWhitespace, .joinNames]
let tags: [NLTag] = [.personalName, .placeName, .organizationName]

tagger.enumerateTags(in: text.startIndex..<text.endIndex, unit: .word, scheme: .nameType, options: options) { tag, tokenRange in
// Get *the most likely tag, and print it if it's a named entity.
    if let tag = tag, tags.contains(tag) {
        print("\(text[tokenRange]): \(tag.rawValue)")
    }
    
    return true
}
