摘要:

我们考虑一个场景,其中人工代理正在阅读由一组叙述组成的文本流,并且它被告知当前正在阅读的文本部分中提到的一些个人的身份。代理人应该学会跟随叙述,从而消除提及的歧义并发现新的个人。我们专注于个人是实体和关系的情况下,我们提出了一个端到端的可训练的记忆网络,学习发现和消除歧义,在网上的方式,执行一次性学习,并处理少量的稀疏监督。我们的系统建立了一个不预先给定的知识库,它在阅读无监督文本时提高了技能。该模型处理叙事中的突然变化,在解决共指时考虑到它们的影响。我们展示了强大的消歧和发现技能,我们的模型在维基百科文档的语料库和新引入的数据集,我们公开提供。

英文摘要:

We consider a scenario where an artificial agent is reading a stream of text composed of a set of narrations, and it is informed about the identity of some of the individuals that are mentioned in the text portion that is currently being read. The agent is expected to learn to follow the narrations, thus disambiguating mentions and discovering new individuals. We focus on the case in which individuals are entities and relations, and we propose an end-to-end trainable memory network that learns to discover and disambiguate them in an online manner, performing one-shot learning, and dealing with a small number of sparse supervisions. Our system builds a not-given-in-advance knowledge base, and it improves its skills while reading unsupervised text. The model deals with abrupt changes in the narration, taking into account their effects when resolving co-references. We showcase the strong disambiguation and discovery skills of our model on a corpus of Wikipedia documents and on a newly introduced dataset, that we make publicly available.
