Text Processing APIs: Language Detection, Similarity, Chinese Conversion, and Metadata Lookup

Text processing is a common layer in search, publishing, content review, data enrichment, and multilingual products. Applications need to detect languages, compare text, normalize Chinese scripts, enrich book records, or retrieve structured cultural content.
