一个基于转换的无作用域情节逻辑形式分析器
A Transition-based Parser for Unscoped Episodic Logical Forms
摘要：
“情节逻辑：无作用域的逻辑形式”（EL-ULF）是一种语义表示，它捕捉了谓词-论元结构以及情节逻辑形式主义中更具有挑战性的语言方面。我们提出了第一个学习的方法，用于将句子解析成ULF，使用越来越多的注释示例。这些结果为今后的改进提供了坚实的基础。我们的方法学习一个序列到序列模型，用于预测修改后的缓存过渡系统内的过渡动作序列。我们评估的有效性类型语法为基础的限制，一个字到符号的词典，并在这项任务中的过渡系统状态功能。我们的系统可在https://github.com/genelkim/ulf-transition-parser上获得。我们还在https://www.cs.rochester.edu/u/gkim21/ulf/resources/上提供了第一个官方注释的ULF数据集。
英文摘要：
"Episodic Logic:Unscoped Logical Form" (EL-ULF) is a semantic representation capturing predicate-argument structure as well as more challenging aspects of language within the Episodic Logic formalism. We present the first learned approach for parsing sentences into ULFs, using a growing set of annotated examples. The results provide a strong baseline for future improvement. Our method learns a sequence-to-sequence model for predicting the transition action sequence within a modified cache transition system. We evaluate the efficacy of type grammar-based constraints, a word-to-symbol lexicon, and transition system state features in this task. Our system is available at https://github.com/genelkim/ulf-transition-parser We also present the first official annotated ULF dataset at https://www.cs.rochester.edu/u/gkim21/ulf/resources/.
