H L Shashirekha

Language Identification is the task of automatically identifying the language(s) in which the content is written in a document (web page, text document). Due to the widespread use of internet, identification of languages has become an important preprocessing step for a number of applications such as machine translation, Part-of-Speech tagging, linguistic corpus creation, supporting low-density languages, accessibility of social media or user-generated content, search engines and information extraction in addition to processing multilingual documents. In a multilingual country like India, Language Identification has wider scope to bridge the digital divide between different language users. This paper presents a brief overview of the challenges involved in automatic language identification, existing methodologies and some of the tools available for language identification.
