Stemming
The Porter Stemming Algorithm is a highly-regarded and commonly utilized method in natural language processing for stemming. Stemming, a process that involves truncating words to their root or base form, is achieved by systematically stripping away suffixes.
Recognized for its efficiency in processing English text, the Porter Stemmer operates on a sequence of rule-based approaches to eliminate common suffixes from words. This ability to streamline words to their stems significantly reduces the dimensionality of text data.
