Book excerpt: This English Chinese dictionary contains the most used 42,000 English words appeared on American and British newspapers. Being possibly the world's first of its kind, a per article per count method is used to measure word frequency. This is very different from the traditional way of frequency counting. Consider the following scenario, Word A appears 100 times on one article and doesn't on 99 other articles. Word B appears 1 time on all 100 articles. Whilst the traditional way treats both cases the same which is 100, per article per count method sees the frequency of word A as 1 and word B as 100. Base on the frequency information, a two digit number presents the tendency of English and American use a word.
