笔记总结自哥大Michael Collins教授自然语言处理课程——成分句法分析以及上下文无关文法(CFGs)部分(课程链接在最后) 初入句法大门,如有错误请多多指教,欢迎交流! Parsing Problem and Context-Free GrammarA…
Syntactic parsing in NLP is the task of working out the grammatical structure of sentences. Some of the purely formal approaches to parsing such as phrase structure grammar, dependency grammar have been successfully employed for a variety of languages. While phrase structure based constituent analysis...

这个过程有一个 implicit assumption: syntactic structure can always be reduced to dependencies in dependency parsing (然而并非如此). 这种 one-to-many 的关系就可以让一句话的词构成一个树,围绕着一个 root (typically a verb) 就能拖着一串词构成句子的感觉 (?)。 用Universal Dependencies (UD) parse ...
CCG parsing is evaluated in terms of labeled dependency F-score, which “take[s] into account the lexical category containing the dependency relation, the argument slot, the word associated with the lexical category, and the argument head word: All four must be correct to score a point” (Cl...

The grammar checking software uses stored parsing algorithms for every word and how the word can be used in good sense to parse your writing. This information is used to determine word order and phrasing in order to evaluate how it fits with standard grammatical textbook and stylebook rules. ...
As to syntactic parsing, robust approaches should be adopted in order to allow for structure building even in the case of local failures. Eventually, partial semantic interpretation can be carried out in order to execute anaphora resolution and a Discourse Model will be built with a reduced ...
量子言治(QNLP)与范畴论 自然语言与量子理论有共同的结构。注意两个语言学原则:组合性(compositionality)和分布性(distributionality)。 Chomsky提出了自然语言语法模型的层次结构,表明(语法)分析问题(the parsing problem)实际上是图灵完备的。现在被称为幺半群的单词问题(word problem for monoids)并且被证明是不可...
The experiments performed on the CCGbank demonstrate that our approach outperforms all previous studies in terms of both supertagging and parsing. Further analyses illustrate the effectiveness of each component in our approach to discriminatively learn from word pairs to enhance CCG supertagging. PDF ...
