Question

What is the role of stemming algorithm in information systems?

Answer 1

Stemming uses a number of approaches to reduce a word to its base from whatever inflected form is encountered. It can be simple to develop a stemming algorithm. Some simple algorithms will simply strip recognized prefixes and suffixes. ... For example, an error can reduce words like laziness to lazi instead of lazy.

Answer 2

In linguistic morphology and information retrieval, stemming is the process of reducing inflected (or sometimes derived) words to their word stem, base or root form—generally a written word form. ... Many search engines treat words with the same stem as synonyms as a kind of query expansion, a process called conflation.
