摘要:

CrisisFACTS Track旨在应对事件跟踪领域的多流实况调查等挑战;参与者的系统从若干灾害相关事件中提取重要事实,同时纳入时间顺序。我们提出了一个组合的检索,重新排序,以及著名的线性规划(ILP)和最大边际相关性(MMR)框架。在前两个模块中,我们探索了各种方法,包括基于实体的基线,预训练和微调的问答系统和ColBERT。然后,我们使用后一个模块作为一个提取的总结组件,考虑多样性和新颖性标准。自动评分运行显示了整个评估设置的强大结果,但也揭示了缺点和挑战。

英文摘要:

The CrisisFACTS Track aims to tackle challenges such as multi-stream fact-finding in the domain of event tracking; participants' systems extract important facts from several disaster-related events while incorporating the temporal order. We propose a combination of retrieval, reranking, and the well-known Integer Linear Programming (ILP) and Maximal Marginal Relevance (MMR) frameworks. In the former two modules, we explore various methods including an entity-based baseline, pre-trained and fine-tuned Question Answering systems, and ColBERT. We then use the latter module as an extractive summarization component by taking diversity and novelty criteria into account. The automatic scoring runs show strong results across the evaluation setups but also reveal shortcomings and challenges.
