Topic Modeling of Research Fields: An Interdisciplinary Perspective
ثبت نشده
چکیده
This paper addresses the problem of scientific research analysis. We present various novel topic models which classify research papers based on topic and language. Moreover, we show various insightful statistics and correlations within and across three research fields: Linguistics, Computational Linguistics, and Education. In particular, we show how topics change over time within each field, what relations exist between topics, what temporal correlations and topic influences can be determined across fields, as well as what trends can be established for some of the world’s natural languages. Finally, we talk about trend prediction and topic suggestion as future extensions of this research.
