About:
Libtextcat is a C library designed for language identification and text categorization using statistical n-gram frequency profiles. It compares input text against pre-built language models to determine the most likely language or genre. This enables developers to integrate robust language detection capabilities into applications requiring automated content analysis or routing.
Key Features:
  • N-gram based statistical analysis
  • Fast and lightweight language identification
  • Support for custom language profiles
  • C library with bindings for other languages
Use Cases:
  • Automatic language detection for content management systems
  • Filtering or routing text based on identified language
  • Spam detection and text classification tasks
Alternatives:
  • cld2 – Google's compact language detector 2, often considered faster but with different license terms
  • fasttext – Facebook's library, offers deep learning-based identification but is heavier and more complex
