Supernova Language Detector V1

A lightweight deterministic language identification system developed by Supernova.

Supported languages

• Nepali
• Hindi
• Sanskrit
• English
• Nepali Latin
• Mixed
• Unknown

to use just two block of code

pip install supernova-lang

next

from supernova_lang import detect

result = detect("नेपाल सुन्दर देश हो।")

print(result.language)
print(result.confidence)
print(result.script)

Design

This detector does not use neural networks or pretrained weights.

It uses deterministic language fingerprints, vocabulary statistics, Unicode/script analysis, and calibrated scoring.

Limitations

Nepali, Hindi, and Sanskrit share the Devanagari script. Very short or ambiguous text may therefore be difficult to classify.

Unknown is returned when there is insufficient evidence.

No pretrained weights

Supernova Language Detector V1 contains no neural-model weights.

Project

Developed as part of the Supernova AI project. How to Use

Supernova Nepali Language Detector V1 is a deterministic language identification system. It does not require a neural model or GPU.

Installation

Clone or download this repository:

git clone https://huggingface.co/Supernova11c/Supernova-Nepali-Language-Detector-V1 cd Supernova-Nepali-Language-Detector-V1

Python Usage

from detector import detect_final_language

text = "नेपाल सुन्दर देश हो।"

result = detect_final_language(text)

print(result)

Example output:

{ "language": "Nepali", "confidence": 0.17, "script": "Devanagari" }

Supported Languages

Supernova V1 can identify:

• Nepali
• Hindi
• Sanskrit
• English
• Nepali Latin
• Mixed
• Unknown

Examples

from detector import detect_final_language

tests = [ "नेपाल सुन्दर देश हो।", "भारत एक विशाल देश है।", "संस्कृतं प्राचीनतमा भाषा अस्ति।", "Artificial intelligence is powerful.", "ma aaja school janchu", "म आज school जान्छु।", "xyz qqq zzz" ]

for text in tests: result = detect_final_language(text)

print(text)
print("Language:", result["language"])
print("Confidence:", result["confidence"])
print("Script:", result["script"])
print()

Output Fields

"language" — detected language or "Unknown".

"confidence" — confidence score between "0.0" and "1.0".

"script" — detected writing system:

• "Devanagari"
• "Latin"
• "Mixed"
• "Unknown"

Design

Supernova V1 is intentionally deterministic.

It does not use:

• Neural inference
• Transformers
• Fine-tuned model weights
• GPU
• External API calls

The detector uses language fingerprints, vocabulary statistics, character patterns, script analysis, and dedicated Nepali-Latin rules.

This makes the system lightweight, reproducible, and suitable for local/offline inference.

Verification

Supernova V1 passed its final standalone benchmark with 7/7 tests.

The release package was also independently imported and tested after packaging.
