Package opennlp.tools.languagemodel

# Interface LanguageModel

public interface LanguageModel
A language model can calculate the probability p (between 0 and 1) of a certain sequence of tokens, given its underlying vocabulary.

- ## Method Summary

  Modifier and Type
  Method
  Description
  `double`
  `calculateProbability(String... tokens)`
  Calculate the probability of a series of tokens (e.g. a sentence), given a vocabulary.
  `String[]`
  `predictNextTokens(String... tokens)`
  Predict the most probable output sequence of tokens, given an input sequence of `tokens`.

- ## Method Details

  - ### calculateProbability

    double calculateProbability(String... tokens)
    Calculate the probability of a series of tokens (e.g. a sentence), given a vocabulary.
    Parameters:
      `tokens` - the text tokens to calculate the `probability` for.
    Returns:
      the probability of the given text tokens in the vocabulary

  - ### predictNextTokens

    String[] predictNextTokens(String... tokens)
    Predict the most probable output sequence of tokens, given an input sequence of `tokens`.
    Parameters:
      `tokens` - a sequence of tokens
    Returns:
      the most probable subsequent token sequence
