Finding Meaningful Chronological Pattern of Key Words in Computer Science Bibliography

摘要

In order to find meaningful patterns of research trends in the computer science and engineering field, we crawl a significant amount of bibliographic information, 3 million or more scholarly papers published from 1956 to 2015. We also make a list of target key words and analyze their frequency rate over the past 60 years based on the terms extracted from the titles and abstracts of the papers. We apply k-means clustering analysis for the target key words, and present a meaningful chronological pattern of target key words in the computer science engineering field over the past 60 years.
