Language Detection: A Comparative Analysis Approaches

Language detection is a crucial task in natural language processing, especially for applications like machine translation and content filtering, requiring the identification of a text's language. A dataset featuring multilingual text samples in 20 languages highlights the complexity of detecting language in short text snippets, which are inherently challenging due to limited context and increased ambiguity. Three language detection models—spaCy Small, spaCy Medium, and XLM-RoBERTa—are evaluated for their effectiveness in this task. Despite XLM-RoBERTa's high accuracy on longer texts, its performance drops significantly for short texts, with longer inference times due to its large size and transformer-based architecture. Conversely, spaCy's small and medium models perform consistently well with short snippets, maintaining high accuracy and efficiency, making them more suitable for real-world applications where quick processing of brief texts is crucial. This analysis underscores the importance of model selection based on task-specific requirements, particularly when dealing with short text language detection.
