Trend Analysis in Machine Learning Research Using Text Mining

This paper aims to identify the trends in machine learning research using text mining. The researcharticles contain significant knowledge and research results. However, they are long and have many noisy results such that it takes a lot of human efforts to analyze them. Text mining can be used to analyze and extract useful information from a large number of research articles quickly and automatically. Text mining is the method of defining innovative, and unseen knowledge from unstructured, semi-structured and structured textual data. This knowldege contributed to very important information that can derive from textual data. In this paper, text mining methods are applied to detect trends of terms that occur in the research articles and how they varies over time. We collected21,906 scientific papers from six top journals in the field of machine learning published in period 1988-2017 and analyzed them using text mining. Our result analysis shows a changing trend of various terms in Machine learning research in three decades. The analysis of our study helps the upcoming researchers to explore the significant research area of machine learning.
