Reductive and generative approaches to management of morphological variation of keywords in monolingual information retrieval: An overview
Abstract
Purpose
The purpose of this article is to discuss advantages and disadvantages of various means to manage morphological variation of keywords in monolingual information retrieval.
Design/methodology/approach
The authors present a compilation of query results from 11 mostly European languages and a new general classification of the language dependent techniques for management of morphological variation. Variants of the different techniques are compared in some detail in terms of retrieval effectiveness and other criteria. The paper consists mainly of an overview of different management methods for keyword variation in information retrieval. Typical IR retrieval results of 11 languages and a new classification for keyword management methods are also presented.
Findings
The main results of the paper are an overall comparison of reductive and generative keyword management methods in terms of retrieval effectiveness and other broader criteria.
Originality/value
The paper is of value to anyone who wants to get an overall picture of keyword management techniques used in IR.
