Our aligner improves F1 score by 2 to 5% with LVCs information. Moreover, the resulting AMR parser achieves the best Smatch scores among other transition-based AMR parsers. We also show that the RevNN framework helps to integrate different linguistic features for improvement in accuracy of ...
A production rule with higher probability is preferred over the rules with lower probability. A PCFG is often generated from an annotated corpus such as the Penn WSJ Treebank is one of the earliest ones in this category. It features 50,000 sentences along with their manually generated parse ...
NLP 预处理与解析至关重要,且非常耗时。本 lib 能快速辅助完成各种琐碎的预处理、解析操作,加速开发进度,把有限的精力用在思考而非 code 上。 如有功能建议、bug,可通过 issue 按模板提出。 非常欢迎各位 NLP 开发者和研究者合作完善本工具包,添加新功能。
之前没咋涉略过 NLP parsing 部分,最近有用到,遇到一个实现的很不错的库:benepar,无论是速度、代码还是性能上。伯克利出品。 而本文要讲的论文就是 benepar 的参考论文:Constituency Parsing with a Self-Attensive Encoder,代码和论文作者都是一个人:Nikita Kitaev,论文发表于 ACL 2018。代码还参考了作者的另一篇...

Last week, while working on new features for our product, I had to find a quick and efficient way to extract the main topics/objects from a sentence. Since I’m using Python, I initially thought that it’s going to be a very easy task to achieve with NLTK. However, when I tried it...
FAParser's new features: Enhanced Pretrain Module of Word Representation Enhanced MST Inference with Multi-Head Attention Module Conditional modeling on interaction between information flows of phrase structure and dependency relation Similar to the design of fairseq, we organize our FAParser as: FAPars...
简介:句法分析(syntactic parsing)是NLP的关键技术,对input句子进行分析得到对应的句法结构;语义分析通常以句法分析的输出,作为input,以获得更多的指示信息。 零、 句法分析基础 句法分析(syntactic parsing)是NLP的关键技术,对input句子进行分析得到对应的句法结构;语义分析通常以句法分析的输出,作为input,以获得更多的指示...
