    Abstract

    There is a phenomenal growth of microblogging-based social communication services and subscriptions in recent years. Through these services, users publish a large number of posts within a short period time, making it extremely hard for readers to keep track of a trending topic. A solution to this issue is text summarisation, which can generate a short summary of a trending topic from multiple posts. Most of the existing summarisation algorithms were proposed for long documents and do not work well for short microblogging posts. The PR (Phrase Reinforcement) algorithm was particularly designed to summarise microblogs, however it is merely able to generate a single-post summary that conveys a single topic, potentially overlooking other important information from the posts. In this paper, we contribute the PRICE (Phrase Reinforcement: Iteration, Clustering and Extraction) algorithm by extending the original PR algorithm with the ability to generate both multi-post and single- post summaries that span over multiple subtopics. Experimental evalu- ation results show that the PRICE algorithm outperforms the original PR algorithm in terms of both ROUGE-1 and Content metrics.
