摘要

Emerging trend detection is a new challenge and attractive topic in text mining. People are looking for the model to identify hot topics in a specific domain, but these models are still not robust in representing topics and neither not suitable for evaluating emerging trends. Our research has constructed an emerging trend detection model for scientific corpora. By viewing each topic as a time series, we have proposed an algorithm of topic identification based on concept hierarchy, and a technique to detect citation types by using Hidden Markov Models. We also build a prototype system to test the method, the evaluation shown that our method is promised to achieve significant results of emerging trends.
