尽管已经进行了大量尝试来联合解析语法和语义,但一个领域的高性能通常是以另一个领域的性能为代价的。这种权衡与大量关注句法语义界面丰富交互的研究相矛盾。我们探索了多种模型架构,使我们能够利用通用分解语义(UDS)数据集中包含的丰富句法和语义注释,联合解析通用依赖关系和 UDS,以获得两种形式主义中最先进的结果。我们分析语法和语义联合模型的行为,在语法-语义界面上找到语言理论支持的模式。然后,我们调查联合建模在多大程度上推广到多语言环境,我们发现 8 种语言具有相似的趋势。
While numerous attempts have been made to jointly parse syntax and semantics, high performance in one domain typically comes at the price of performance in the other. This trade-off contradicts the large body of research focusing on the rich interactions at the syntax–semantics interface. We explore multiple model architectures that allow us to exploit the rich syntactic and semantic annotations contained in the Universal Decompositional Semantics (UDS) dataset, jointly parsing Universal Dependencies and UDS to obtain state-of-the-art results in both formalisms. We analyze the behavior of a joint model of syntax and semantics, finding patterns supported by linguistic theory at the syntax–semantics interface. We then investigate to what degree joint modeling generalizes to a multilingual setting, where we find similar trends across 8 languages.
