Crate charabia

Expand description

Charabia library tokenize a text detecting the Script/Language, segmenting, normalizing, and classifying it.

Examples

Tokenization

use charabia::Tokenize;

let orig = "Thé quick (\"brown\") fox can't jump 32.3 feet, right? Brr, it's 29.3°F!";

// tokenize the text.
let mut tokens = orig.tokenize();

let token = tokens.next().unwrap();
// the lemma into the token is normalized: `Thé` became `the`.
assert_eq!(token.lemma(), "the");
// token is classfied as a word
assert!(token.is_word());

let token = tokens.next().unwrap();
assert_eq!(token.lemma(), " ");
// token is classfied as a separator
assert!(token.is_separator());

Segmentation

use charabia::Segment;

let orig = "The quick (\"brown\") fox can't jump 32.3 feet, right? Brr, it's 29.3°F!";

let mut segments = orig.segment_str();

assert_eq!(segments.next(), Some("The"));
assert_eq!(segments.next(), Some(" "));
assert_eq!(segments.next(), Some("quick"));

Charabia comes with default features that can be deactivated at compile time, this features are additional Language supports that need to download and/or build a specialized dictionary that impact the compilation time. Theses features are listed in charabia’s cargo.toml and can be deactivated via dependency features.
