Struct lingua::LanguageDetector[−][src]

pub struct LanguageDetector { /* fields omitted */ }
Expand description

This struct detects the language of given input text.

Implementations

impl LanguageDetector[src]

pub fn detect_language_of<T: Into<String>>(&self, text: T) -> Option<Language>[src]

Detects the language of given input text. If the language cannot be reliably detected, None is returned.

pub fn compute_language_confidence_values<T: Into<String>>(
    &self,
    text: T
) -> Vec<(Language, f64)>[src]

Computes confidence values for each language considered possible for the given input text.

A vector of all possible languages is returned, sorted by their confidence value in descending order. The values that this method computes are part of a relative confidence metric, not of an absolute one. Each value is a number between 0.0 and 1.0. The most likely language is always returned with value 1.0. All other languages get values assigned which are lower than 1.0, denoting how less likely those languages are in comparison to the most likely language.

The vector returned by this method does not necessarily contain all languages which the calling instance of LanguageDetector was built from. If the rule-based engine decides that a specific language is truly impossible, then it will not be part of the returned vector. Likewise, if no ngram probabilities can be found within the detector’s languages for the given input text, the returned vector will be empty. The confidence value for each language not being part of the returned vector is assumed to be 0.0.
