Abstract

Abstract: The objective of this paper is to propose a novel entity-oriented timeline summarization from multiple documents. To achieve this, this paper firstly proposes a topic model to simultaneously model the dynamic topics and the entity’s participation. An efficient Gibbs sampler is also developed for this model. Then each sentence is allocated a score based on the discovered topics and the sentences with high score are selected as summaries. Experimental results on real-world datasets verify that the proposed model can not only generate summaries for entities, but also outperform the baseline model on Rouge evaluation.

Key words: multiple document summarization, topic model, natural language process
