Class: NaturalLanguageClassifier

Represents a simple natural language classifier.

Constructor

Creates a new instance of the NaturalLanguageClassifier class.

new NaturalLanguageClassifier()

Methods

.addDocument(document, category)

Adds a document to the classifier with the given category.

  • document (string): The text content of the document.
  • category (string): The category of the document.

.train()

Trains the classifier by calculating feature and category probabilities.

.classify(document, context)

  • document (string): The text content of the document to classify.
  • context (string): Additional context for better classification accuracy.
  • Returns: An array of predicted categories for the input document.

.loadModelFromFile(filePath)

Loads the classifier's model data from a JSON file.

  • filePath (string): The path to the JSON file containing the model data.

.saveModelToFile(filePath)

Saves the classifier's model data to a JSON file.

  • filePath (string): The path to the JSON file to save the model data.
