CHANGE OF TOPICS OVER TIME - Tracking Topics by their Change of Meaning

Gerhard Heyer, Florian Holz, Sven Teresniak

Abstract

In this paper we present a new approach to the analysis of topics and their dynamics over time. Given a large amount of news text on a daily basis, we have identified “hotly discussed” concepts by examining the contextual shift between the time slices. We adopt the volatility measure from econometrics and propose a new algorithm for frequency-independent detection of topic drift.
