基本解釋

This paper illustrates the formalization model employed in Head-driven Phrase Structure Grammar.
簡(jiǎn)要評(píng)述了中心語(yǔ)驅(qū)動(dòng)短語(yǔ)結(jié)構(gòu)語(yǔ)法所采用的語(yǔ)言理論形式化方法。
To implementation of efficient parsing of grammars, a new class of phrase structure grammars called overlap-free grammar(OFG) with heavily restricted rewriting rules is defined.
為了實(shí)現(xiàn)有效的文法解析，定義了一種生成規(guī)則受限的短語(yǔ)結(jié)構(gòu)文法，稱(chēng)為無(wú)重疊生成文法。
Idea of the algorithm is to induce three kinds of trees from lexicalized tree bank. Then the method of Head-driven Phrase Structure Grammar(HPSG) was applied to extract lexicalized tree from corpus.
該算法的主要思想是從詞匯化樹(shù)庫(kù)中歸納出三種類(lèi)型的詞匯化樹(shù)，然后利用了中心詞驅(qū)動(dòng)短語(yǔ)結(jié)構(gòu)文法的方法從語(yǔ)料庫(kù)自動(dòng)提取結(jié)構(gòu)合理的詞匯化樹(shù)；
