# parattice: Recursive paraphrase lattice generator 🔄

This library takes a sentence and a paraphrase corpus, recursively finds

paraphrases based on the corpus, expands the given sentence, and generates a

paraphrase lattice.

This library also provides a method to search a phrase in the paraphrase

lattice.

## Example

This example generates a paraphrase lattice and searches a phrase in the generated lattice.

```rust

use parattice::Lattice;

use parattice::LatticeKMP;

use parattice::PaRattice;

// initialization

let paradict = vec![

    vec![

        vec!["blood", "stem", "cell"],

        vec!["造血", "幹", "細胞"],

        vec!["hematopoietic", "stem", "cell"],

    ],

    vec![

        vec!["造血", "幹", "細胞", "移植"],

        vec!["hematopoietic", "stem", "cell", "transplantation"],

    ],

    vec![vec!["stem", "cell"], vec!["幹", "細胞"]],

    vec![

        vec!["幹", "細胞", "移植"],

        vec!["rescue", "transplant"],

        vec!["stem", "cell", "rescue"],

    ],

    vec![vec!["rescue"], vec!["救命"]],

    vec![vec!["blood"], vec!["血液"]],

];

let parattice = PaRattice::new(paradict);

// lattice generation

let words = vec!["造血", "幹", "細胞", "移植"];

let lattice = parattice.get_lattice(&words, true, 2);

// dump a generated lattice

println!(lattice.dump_dot(true));

// serialization & deserialization

let bytes = lattice.to_bytes();

let new_lattice = Lattice::new_from_bytes(&bytes);

// search

let kmp = LatticeKMP::new(vec!["幹", "細胞"]);

let results = kmp.search(&new_lattice);

for result in &results {

    for edge in result {

        print!("({}, {}) ", edge.0, edge.1);

    }

    println!();

    let s = lattice.get_trunk_span(result.clone());

    for edge in &s {

        print!("({}, {}) ", edge.0, edge.1);

    }

    println!("\n===========");

}

```
