Input-based Language Modelling in the Design of High Performance Text Input Techniques.
R. William Soukoreff, Ian Scott MacKenzie · 2003
We present a critique of language-based modelling for text input research, and propose an alternative inputbased approach. Current language-based statistical models are derived from large samples of text (corpora). However, this text reflects only the output, or final result, of the text input task. We argue that this weakens the utility of the model, because, (1) users' language is typically quite different from that in any corpus; punctuation symbols, acronyms, slang, etc. are frequently used. (2) A corpus does not reflect the editing process used in its creation. (3) No existing corpus captures the input modalities of text input devices. Actions associated with keys such as Shift, Alt, and Ctrl are missing.
