Abstract：Aiming at Chinese-Vietnamese bilingual news event storyline analysis, a generative model for event storyline is proposed based on global/local word pairs’ co-occurrence distribution. Firstly, the detected news topic word distribution was used as global words to characterize a global event, Then time, person, place and other event elements in the news segment divided by certain time granularity are used as local words. The are co-occurrence of global and local words is analyzed and used as supervised information, with RCRP algorithm and bilingual aligned words together, which are integrated into a bilingual topic model to get sub-topic distribution under corresponding time slice. Finally, by the sub-topic distribution representing the developing process of an event, a generative model to storyline was constructed. On Chinese-Vietnamese mixed news set crawled from the internet, the comparative experiments of storyline generation are conducted, proving that the proposed bilingual news storyline is model got better effect than the other methods. Key words Chinese-Vietnamese; news event storyline; global/local co-occurrence words; sub-topic distribution; bilingual topic model
