intent-classifier 0.1.0

//! # Intent Classification Library
//!
//! A flexible few-shot intent classification library for natural language processing.
//! This library provides a simple API for classifying user intents from text using
//! machine learning and rule-based approaches.
//!
//! ## Features
//!
//! - **Few-shot learning**: Train the classifier with minimal examples
//! - **Bootstrap data**: Comes with pre-trained examples for common intents
//! - **Feedback learning**: Improve accuracy through user feedback
//! - **Async support**: Fully async API for non-blocking operations
//! - **Serializable**: Export/import training data as JSON
//! - **Configurable**: Customize behavior through configuration
//!
//! ## Quick Start
//!
//! ```rust
//! use intent_classifier::{IntentClassifier, TrainingExample, TrainingSource, IntentId};
//!
//! #[tokio::main]
//! async fn main() -> Result<(), Box<dyn std::error::Error>> {
//!     // Create a new classifier
//!     let classifier = IntentClassifier::new().await?;
//!
//!     // Predict an intent
//!     let prediction = classifier.predict_intent("merge these JSON files together").await?;
//!     println!("Intent: {}, Confidence: {:.3}", 
//!              prediction.intent, prediction.confidence.value());
//!
//!     // Add custom training data
//!     let example = TrainingExample {
//!         text: "calculate the sum of these numbers".to_string(),
//!         intent: IntentId::from("math_operation"),
//!         confidence: 1.0,
//!         source: TrainingSource::Programmatic,
//!     };
//!     classifier.add_training_example(example).await?;
//!
//!     // Get statistics
//!     let stats = classifier.get_stats().await;
//!     println!("Training examples: {}", stats.training_examples);
//!
//!     Ok(())
//! }
//! ```
//!
//! ## Examples
//!
//! For more examples, see the `examples/` directory in the repository.
