The langdetect library's architecture is centered around a Language Detector API that serves as the primary entry point. This API orchestrates the language detection process by loading necessary Language Profile Store data and delegating core detection tasks to the Core Detection Engine. The Core Detection Engine is responsible for the actual language identification, which involves processing input text using the Text Preprocessing & N-gram Generation utility to extract linguistic features and querying the Language Profile Store for statistical language models. An External Profile Generation Tool (a conceptual Java-based component) is responsible for initially populating the Language Profile Store by utilizing the Text Preprocessing & N-gram Generation component to prepare raw text data for profile creation. This clear separation of concerns facilitates efficient language detection and allows for external management of language profile generation.
Language Detector API [Expand]
The public-facing interface for the langdetect library, responsible for system initialization, profile loading, and orchestrating the language detection process.
Related Classes/Methods:
Core Detection Engine [Expand]
Encapsulates the primary algorithms for language identification, processing text, extracting features, and calculating language probabilities.
Related Classes/Methods:
Language Profile Store [Expand]
Manages the statistical language profiles (n-gram frequencies) essential for the detection algorithm, handling their storage, retrieval, and optimization.
Related Classes/Methods:
A utility component providing functions for text normalization and the generation of n-grams, which are fundamental linguistic features.
Related Classes/Methods:
(Conceptual) An external Java-based tool (langdetect.jar) responsible for generating the initial language profiles from large text corpora. It utilizes the Text Preprocessing & N-gram Generation component to prepare data before generating profiles, which are then consumed by the Language Profile Store. As an external Java application, no direct Python source code reference is available within this project's context.
