  "abstract": "<p>Dynamic topic models (DTMs) capture the evolution of topics and trends in time series data.<br>\nCurrent DTMs are applicable only to monolingual datasets. In this paper we present the multilingual<br>\ndynamic topic model (ML-DTM), a novel topic model that combines DTM with an existing multilingual<br>\ntopic modeling method to capture crosslingual topics that evolve across time. We present<br>\nresults of this model on a parallel German-English corpus of news articles and a comparable corpus<br>\nof Finnish and Swedish news articles. We demonstrate&nbsp;the capability of ML-DTM to track significant<br>\nevents related to a topic and show that it finds&nbsp;distinct topics and performs as well as existing<br>\nmultilingual topic models in aligning cross-lingual&nbsp;topics.</p>",
