Stemming

ˈstɛmɪŋ

Stemming is a natural language processing technique used to reduce words to their root or base form. This process involves removing prefixes and suffixes from words to standardize them for analysis, allowing for the grouping of different forms of a word under a single term. For instance, the words 'running', 'runner', and 'ran' can all be stemmed to their root 'run'. Stemming is commonly used in information retrieval, text mining, and search engines to improve the accuracy of search results by treating variations of a word as equivalent. By simplifying the analysis of text data, stemming helps in enhancing the performance of various NLP applications.
