A Temporal Pattern Analysis for Appearance Frequencies of Foreign Words Using Newspaper Article Database

Abstract

We are studying temporal transitions of word frequencies through vocabulary analyses using large-scale databases.Specifically, this paper focuses on the use of foreign words.We choose 109 words from governmental documents.Then, we statistically investigate the appearance frequencies of the words using a newspaper full-text database accumulated for 16 years.Our analysis shows that the word appearance frequency patterns can be classified roughly into four types.Then, linguistic and social background for those types are discussed introducing indices such as “understanding rate” and the first-use year of the words.
