Based on experiments on a test corpus of business news in German language, this talk shows different methods that can be applied for mining trends. The main discussion outcome after comparing the different results in this talk is based on the question: what does the knowledge-based perspective actually bring to trend mining?

Starting with the description of the test corpus and its content, I will introduce briefly two state-of-the-art methods: topic models and k-means clustering that have been applied on the test corpus. Showing the experiment results, I will discuss the different possibilities of exploiting these approaches for mining trends. In the second part of the talk, I will present the knowledge-based perspective on mining trends. My knowledge-based trend mining model, grounded in the trend template, will be discussed thoroughly by showing its formalization, implementation as well as the preliminary results from experiments on the test corpus.
