WHAT IS MACHINE TRANSLATION

translation carried out by a computer.Explanation:-Machine translation (MT) is automated translation. It is the process by which computer software is used to translate a text from one natural language (such as English) to another target language (such as chinese).

SHORT HISTORY

The first set of proposals for computer based machine translation was presented in 1949 by Warren WeaverThese proposals were based on information theory On 7 January 1954 the Georgetown-IBM experiment was held in New York at the head office of IBMThis was the first public demonstration of a machine translation systemEarly systems used large bilingual dictionaries and hand-coded rules for fixing the word order in the final output

HOW MACHINE TRANSLATION WORK

THERE ARE TWO TYPES OF MACHINE TRANSLATION SYSTEM: RULES-BASED AND STATISTICAL

Rules-based systems use a combination of language and grammar rules plus dictionaries for common words. Specialist dictionaries are created to focus on certain industries or disciplines. Rules-based systems typically deliver consistent translations with accurate terminology when trained with specialist dictionaries.

Statistical machine translation (SMT) is a machine translation paradigm where translations are generated on the basis of statistical model whose parameters are derived from the analysis of bilingual text
