Outline of Final Research Achievements

We wrote computer programs : (i) a program measuring the similarity between words such as edit distance, cosine similarity of character n-gram vectors, and string kernel, (ii) a program measuring the information amount that a word has given its preceding context using the language model trained on news paper articles, (iii) a program that is used in the experiment to measure the reading time of human subjects. With an ethical approval, we conducted experiments to measure reading time, where the spellings of some words are intentionally changed. From the experimental data, we derived the statistical trend among reading time, spelling, and the information amount of a word given its preceding context.
