3. Usage Examples

// Example 1: Semantic Similarity
let engine = JuliaNLPEngine::new()?;

let text1 = "async parallel processing with rayon";
let text2 = "concurrent execution using rayon library";

let similarity = engine.analyze_similarity(text1, text2)?;
println!("Similarity: {:.4}", similarity);  // ~0.85

// Example 2: Fuzzy Matching
let query = "paralell procesing";  // Typos
let candidates = vec![
    "parallel processing",
    "serial execution",
    "concurrent handling",
];

let matches = engine.fuzzy_match(query, candidates, Some("jarowinkler"))?;

for (candidate, score) in matches {
    println!("{}: {:.4}", candidate, score);
}

// Example 3: Feature Extraction
let text = "The quick brown fox jumps over the lazy dog";
let features = engine.extract_features(text)?;

println!("Features: {:?}", features);
// TextFeatures {
//     length: 44,
//     words: 9,
//     unique_words: 9,
//     avg_word_length: 3.89,
//     lexical_diversity: 1.0
// }

4. Advanced Distance Algorithms

# Available algorithms in StringDistances.jl

algorithms = [
    "levenshtein",      # Edit distance
    "damerau",          # Damerau-Levenshtein
    "hamming",          # Hamming distance
    "jaro",             # Jaro distance
    "jarowinkler",      # Jaro-Winkler
    "cosine",           # Cosine distance
    "jaccard",          # Jaccard index
    "overlap",          # Overlap coefficient
    "ratcliff",         # Ratcliff-Obershelp
]

# Compare all
function compare_all_algorithms(str1::String, str2::String)
    for algo in algorithms
        dist = get_distance_algorithm(algo)
        sim = 1.0 - compare(str1, str2, dist)
        println("$algo: $sim")
    end
end

Ejemplos

Example 1: Code Similarity

let engine = JuliaNLPEngine::new()?;

let code1 = "fn process_parallel(data: Vec<i32>) -> Vec<i32>";
let code2 = "async fn parallel_process(input: Vec<i32>) -> Vec<i32>"; 

let similarity = engine.analyze_similarity(code1, code2)?;
println!("Code similarity: {:.4}", similarity);

Example 2: Typo-Tolerant Search

let typo_query = "memry optmization";
let correct_terms = vec![
    "memory optimization",
    "memory allocation",
    "cache optimization",
    "parallel execution",
];

let matches = engine.fuzzy_match(
    typo_query,
    correct_terms,
    Some("jarowinkler")
)?;

// Returns: [("memory optimization", 0.92), ...]

Benchmarks

Best Practices

✅ DO's

1. Preprocess text before analysis
2. Use appropriate algorithm for use case
3. Batch operations when possible
4. Cache Julia runtime
5. Handle errors from FFI

❌ DON'Ts

1. Don't reinitialize Julia for each call
2. Don't use for simple string equality
3. Don't skip text normalization
4. Don't ignore algorithm selection
