Automatic Language Processing Advisory Committee (ALPAC)

|

One of the constituent parts of the ALPAC report was a study comparing different levels of human translation with machine translation output, using human subjects as judges. The human judges were specially trained for the purpose. The evaluation study compared … Read More

Approaches in machine translation

|

Pyramid showing comparative depths of intermediary representation, interlingual machine translation at the peak, followed by transfer-based, then direct translation. Machine translation can use a method based on linguistic rules, which means that words will be translated in a linguistic way … Read More

Round-trip translation

|

Although this may intuitively be a good method of evaluation, it has been shown that round-trip translation is a, “poor predictor of quality”. The reason why it is such a poor predictor of quality is reasonably intuitive. When a round-trip … Read More

Translation process with machine translation

|

The translation process may be stated as: Decoding the meaning of the source text; and Re-encoding this meaning in the target language. Behind this ostensibly simple procedure lies a complex cognitive operation. To decode the meaning of the source text … Read More

Evaluation of machine translation

|

Various methods for the evaluation for machine translation have been employed. This article will focus on the evaluation of the output of machine translation, rather than on performance or usability evaluation. Before covering the large scale studies, a brief comment … Read More

History of the machine translation

|

The idea of machine translation may be traced back to 17th century. In 1629, René Descartes proposed a universal language, with equivalent ideas in different tongues sharing one symbol. In the 1950s, The Georgetown experiment (1954) involved fully-automatic translation of … Read More

Machine translation

|

Machine translation, sometimes referred to by the abbreviation MT, is a sub-field of computational linguistics that investigates the use of computer software to translate text or speech from one natural language to another. At its basic level, MT performs simple … Read More
