Evaluation of Typing Efficiency Using Language Model for the Chinese Typewriter

The predictive text with “Radiating style” refers to the personalized distribution of Chinese characters in the tray bed of the Chinese typewriter. With this arrangement, the typing speed reached 60- 80 words per minute (WPM). In the field of natural language processing (NLP), there is little research on this topic. To fill this gap in the literature, we identified some “Radiating style” patterns from the predicted text, and proposed a language model to evaluate the input efficiency of three different versions of the tray beds: Traditional Chinese tray bed (TCTB), Simplified Chinese tray bed (SCTB), and personalized setting panel. The research demonstrates that the tray bed setting and query of the Chinese typewriter inherit some Chinese language properties, and should be considered as one important step of Chinese natural language processing (CNLP). It is also valuable as a reference to improve the inputting panel of the future for the smart Chinese Language Information Processing Systems (CLIPS).
