Delphi-Based Evaluation of Mobile Online Translation Tools

Mobile online translation (MOT) is a new form of application of machine translation in the age of mobile learning. Nowadays, there are lots of MOT apps in Android app store. Since the techniques used in MOT apps and their functions are different, their features are also different. In order to objectively evaluate MOT apps for selecting suitable translation tools, we have studied a Delphi-based evaluation method. In this paper, firstly, we describe the basic functions and realization mechanisms of MOT tools, and then we analyze 10 factors which should be considered in the evaluation of MOT tools, on the basis of the analyses, we propose the Delphi-based evaluation method with a relatively complete indicator system, and we also determine the weights of every indicator by using Delphi. The experiment results on 6 MOT apps show that the evaluation method is practical and objective for selecting suitable translation tools.
