The amount of multilingual information that needs to be available today in parallel form is far too overwhelming for the human translation industry to manage. But both Machine Translation and Human Translation may be required, depending on the type of translation needed and the ultimate use of the translated text. Machine Translation is the use of computer software to translate text from one natural language into another.
Translation is anything but simple.
It's not a mere substitution for each word, but being able to know 'all of the words' in a given sentence or phrase and how one may influence the other. Individuals translate text from one natural language into another in order to provide Human Translation Services. Many times, it is more difficult to find humans that maintain both the comprehensive knowledge of the languages required for the translation and expert-level insight of a specific domain. A human translator can translate about 2,000 to 3,000 words in a day. The cost of a high-end MT solution pays for itself within the first year of use.
