Issues in Indian languages computing in particular reference to search and retrieval in Telugu language

Abstract

PurposeThe purpose of this paper is to discuss the various issues involved in Indian languages computing, particularly Telugu, like creating, displaying, searching and retrieving digital content. The paper also aims to emphasize the issues involved in retrieval in Indian languages. The complexities presented by the grammar, syntax and morphology of Indian languages are discussed.Design/methodology/approachThe paper undertakes and presents descriptive study of the issues and challenges in Indian languages computing in general and Telugu language in particular.FindingsThe problem of multilingual information retrieval in Indian languages is multi‐pronged. A major observation of this study is that, though digital content is available in Indian languages, it is mostly in non‐standard encoding format and fonts. There is an urgent need to work in the area of developing search algorithms for Indian languages, like soundex and metaphones to tolerate spelling variations and mistakes that a user might make in queries and suggest correct spelling(s).Practical implicationsWith existing technologies libraries can now build online catalogues in the language of the documents or build digital repositories with content in various Indian languages. Though a few library automation software like NewGenLib and digital library software like DSpace, etc. are offering Unicode support for Indian languages, they do not allow for different types of search such as truncation search, word variants, etc. The present study is a step towards developing algorithms for indexing and searching in Indian languages.Originality/valueThe paper addresses various issues in Indian language computing with emphasis on search and retrieval.
