A New Stemmer to Improve Information Retrieval

Abstract

A stemming is a technique used to reduce words to their root form, by removing derivational and inflectional affixes. The stemming is widely used in information retrieval tasks. Many researchers demonstrate that stemming improves the performance of information retrieval systems. Porter stemmer is the most common algorithm for English stemming. However, this stemming algorithm has several drawbacks, since its simple rules cannot fully describe English morphology. Errors made by this stemmer may affect the information retrieval performance.
