[Sample] Vietnamese text classification with Natural Language API #14679

Sample Request: Vietnamese Text Classification

Reporter: NHAM QUOC HUAN · NLP Labs Vietnam

Background

We are building Vietnamese NLP applications at NLP Labs Vietnam using Google Cloud Natural Language API. The current sample collection lacks any Vietnamese language example, despite the API supporting it.

Gap

Looking at natural-language/ samples — all examples use English text. Vietnamese (vi) is a supported language per the API documentation, but no sample demonstrates this.

Proposed Addition

A minimal Vietnamese example in the existing natural-language/ samples:

# natural-language/samples/snippets/analyze_sentiment_vi.py

def analyze_sentiment_vietnamese(text_content: str):
    """Analyzes sentiment of Vietnamese financial text."""
    from google.cloud import language_v2

    client = language_v2.LanguageServiceClient()
    document = language_v2.Document(
        content=text_content,
        type_=language_v2.Document.Type.PLAIN_TEXT,
        language_code="vi",  # Vietnamese
    )
    sentiment = client.analyze_sentiment(
        request={"document": document}
    ).document_sentiment
    return sentiment

Scope: Small addition — 1 Python file + test + README note.

We are ready to submit a PR with this sample.
