Comprehension‐Dependent Cortical Activation During Speech Comprehension Tasks with Multiple Languages
In this era of globalization, a second language (which is often English in Japan) has become prevalent and important. To investigate whether cerebral hemodynamics could represent the speech comprehension level of a learned language, we measured the brain activation of 46 non‐fluent Japanese learners of English using functional near‐infrared spectroscopy while performing speech comprehension tasks. Tasks were given in three languages: English (sec…
Extracting terms by a combination of term frequency and a measure of term representativeness
This article describes a method for extracting terms that combines term frequency with a novel measure of term representativeness (i.e., informativeness or domain specificity). The measure is defined as the normalized distance between the word distribution in the documents which contain the term and the word distribution in the whole corpus. The measure is particularly effective in discarding uninformative terms that frequently appear and has a w…
