Assamese Inflectional Rule-Based Stemmer

Received Date:23 March 2023, Accepted Date:26 June 2023, Published Date:02 November 2023


The research paper presents an Assamese Inflectional Rule-Based Stemmer with supervised rules that tackles the issues brought on by the language’s complex morphology. Objectives: The goal is to create a stemmer that accurately captures a word’s context while taking its inflectional forms into account. Methods: This was accomplished using a rule-based approach that had been improved by the incorporation of Parts-Of-Speech tagged (POS-tagged) data with Assamese WordNet. A corpus of 50,000 words from diverse sources was used, together with POS-tagged data. Assamese WordNet was also added to improve the stemmer’s performance. Findings: An accuracy of 91% achieved utilising the tagged data, surpassing the 86% accuracy attained without the use of tags, the evaluation findings showed a substantial improvement. The suggested stemmer successfully captures word meanings and their inflectional variations by combining POS tagging and utilizing Assamese WordNet. Novelty: Applications like sentiment analysis and information retrieval systems benefit from this research’s advancement of Assamese language processing. The development of accurate stemming methods successfully closes the prevailing gap in elemental processing. This development enables information retrieval systems to operate more quickly and accurately.
