摘要:

语义表示(AMR)是一种自然语言的语义表示,其嵌入与传统任务相关的注释,诸如命名实体识别、语义角色标注、词义消歧和共指消解。我们描述了一个基于转换的AMR解析器,它在线性时间内从左到右解析句子。我们进一步提出了一个测试套件,评估有助于比较AMR解析器的特定子任务,并表明我们的解析器在LDC2015E86数据集上与最先进的解析器竞争,并且在恢复命名实体和处理极性方面优于最先进的解析器。

英文摘要:

Meaning Representation (AMR) is a semantic representation for natural language that embeds annotations related to traditional tasks such as named entity recognition, semantic role labeling, word sense disambiguation and co-reference resolution. We describe a transition-based parser for AMR that parses sentences left-to-right, in linear time. We further propose a test-suite that assesses specific subtasks that are helpful in comparing AMR parsers, and show that our parser is competitive with the state of the art on the LDC2015E86 dataset and that it outperforms state-of-the-art parsers for recovering named entities and handling polarity.
