Nowadays, online Machine Translation (MT) is used widely with translation software, such as Google and Babylon, being easily available and downloadable. This study aims to test the translation quality of these two machine systems in translating Arabic news headlines into English. 40 Arabic news headlines were selected from three online sources, namely "Aljazeera," "daralhayat," and "Aawsat," where their English manually-translated versions were available. The selected data was evaluated by conducting criteria of Hutchins and Somers (1992) to find the assessment of each system outputs. Besides that, the selected data was also examined to find the types of translation techniques that are available in both machine outputs. A questionnaire was assigned to experienced professionals to evaluate the outputs to examine and determine which system was better to use in translating the collected data. The evaluation was based on criteria proposed by Hutchins and Somers. The findings indicated that both Google and Babylon had 80% of clarity, and Google scored a higher value of accuracy, i.e. 77.5%, compared to 75% of accuracy for Babylon. However, Babylon scored a higher value for style, i.e. 72.5%, compared to a score of 70% by Google. Nevertheless, the results revealed that online MT is undergoing improvement, and it has the potential to be one of the elements of globalization. As implication, the students could use online MT for learning purposes easily and quickly. (Contains 11 figures and 2 tables.)
