Vaporetto is a fast and lightweight pointwise prediction based tokenizer.
```rust use std::fs::File;
use vaporetto::{Model, Predictor, Sentence};
let f = File::open("../resources/model.bin")?; let model = Model::read(f)?; let predictor = Predictor::new(model, true)?;
let mut buf = String::new();
let mut s = Sentence::default();
s.updateraw("まぁ社長は火星猫だ")?; predictor.predict(&mut s); s.filltags(); s.writetokenizedtext(&mut buf); assert_eq!( "まぁ/名詞/マー 社長/名詞/シャチョー は/助詞/ワ 火星/名詞/カセー 猫/名詞/ネコ だ/助動詞/ダ", buf, );
s.updateraw("まぁ良いだろう")?; predictor.predict(&mut s); s.filltags(); s.writetokenizedtext(&mut buf); assert_eq!( "まぁ/副詞/マー 良い/形容詞/ヨイ だろう/助動詞/ダロー", buf, ); ```
The following features are disabled by default:
kytea - Enables the reader for models generated by KyTea.train - Enables the trainer.portable-simd - Uses the portable SIMD API instead
of our SIMD-conscious data layout. (Nightly Rust is required.)The following features are enabled by default:
std - Uses the standard library. If disabled, it uses the core library instead.cache-type-score - Enables caching type scores for faster processing. If disabled, type scores are calculated in a straightforward manner.fix-weight-length - Uses fixed-size arrays for storing scores to facilitate optimization. If disabled, vectors are used instead.tag-prediction - Enables tag prediction.charwise-pma - Uses the Charwise Daachorse instead of the standard version for faster prediction, although it can make to load a model file slower.The distributed models are compressed in the zstd format. If you want to load these compressed models, you must decompress them outside of the API.
rust
// Requires zstd crate or ruzstd crate
let reader = zstd::Decoder::new(File::open("path/to/model.bin.zst")?)?;
let model = Model::read(reader)?;
You can also decompress the file using the unzstd command, which is bundled with modern Linux distributions.
