依存句法解析《Structured Training for Neural Network Transition-Based Parsing》,程序员大本营,技术文章内容聚合第一站。
We present structured perceptron training for neural network transition-based dependency parsing. We learn the neural network representation using a gold corpus augmented by a large number of automatically parsed sentences. Given this fixed network representation, we learn a final layer using the ...
接下来解释什么叫transition-based。依旧是论文的例子。图: parser有以下几项: 一个stackS,root第一个入栈,栈顶靠右,图中栈顶是词good。 一个bufferB,第一个元素是在最左边,按照句子的顺序开始。 一个放dependency边的集合A。 transition的集合 在本文中,有如下几种transition: LEFT-ARC(l): 往A中增加一条s1...
主要介绍了两中命名实体识别的模型,第一种是老生常谈的bi-LSTM-CRF模型,这个在论文的实践领域中,已经有很多改进的方法,比如添加字符级别的嵌入,加入attention机制等等,第二种是一个目前我还未读到的一个模型,Transition-Based Chunking Model,它使用类似于基于过渡的依赖解析(transition-based dependency parsing)的算...
论文地址:https://cs.stanford.edu/~danqi/papers/emnlp2014.pdf 论文名称:一种使用神经网络(三层)的精准快速的依存句法分析 特征提取是基于Transition-based Dependency Parsing 基于转移的依存句法分析,从而可以有效精简特征数量 例如: 词特征18个: 1、栈区和缓存区分别提取前三个词 合计6个特征 2、栈... 查看...
Dependency Parsing 主要有两种方法:Transition-based和 Graph-based。 DeepBiaffine Attentionfor NeuralDependency Parsing 基于图的依存句法分析从左向右解析句子,针对句中的每个词,找该词的head词(该词到head词之间的arc)以及从该词到head词之间的依存关系类型,即需要解决两个问题:哪两个节点连依存弧以及弧的标签是...
Dependency Parsing目前有两种做法: (1) Transition-Based:定义actions,在当前state,选择不同的action进入不同的下一个state (2) Graph-Based: 关键是score function 构建树的过程中有三种解码算法: (1) dynamic programming {Three new probabilistic models for dependency parsing: An exploration} ...
