查询词典 parsing

When processing text with , it is possible to attach "action code" to any lexing or parsing event.

当用处理文本时，可以在任何词法分析或解析事情上，附上"行动代码"。

Arithmetic expression of lexical analysis and parsing, translation theory test, and we hope to explore.

算术表达式的词法分析和语法分析，编译原理的实验，希望能和大家探讨。

Design and implement C language, language analysis program to realize the arithmetic expression parsing.

详细说明：设计并实现C语言的语分析程序，实现对算术表达式的语法分析。

In this paper it analyzes the execution process of SQL statement in Oracle database and finds out that reducing times of SQL statement parsing and optimizing CBO are the emphases of SQL performance tuning.Then it validates the key role of using bound variable and cache cursor in enhancing performance of SQL with example.

从分析ORACLE数据库中SQL语句执行原理入手，指出减少SQL语句的解析次数和优化CBO是SQL性能优化的重点，并用实例验证了使用绑定变量和高速缓存游标在提高SQL性能方面的重要作用。

Adopt that the computer-aided design means has beenunderway the analysis in this paper, and give out the calculating machine parsing process in order to be convenient for comprehend .

文中采用了计算机辅助设计方法对其进行了分析，并给出了计算机分析过程以便于理解。

After reviewing the relevant theories and parsing algorithms of syntax analysis researches, a brand new Chinese parsing model is proposed in this paper based on Operator Precedence Grammar, in which the parsing process of Chinese sentences is formalized as a evaluating process of expressions with binary operators that may appear implicitly.

在研究了自然语言的相关句法理论和分析算法之后，本文以崭新的思想构建了一个汉语句子分析模型。

ER semantics contributes to correcting segmentation ambiguity and partially solving unlogged words problem at segmentation stage, to generating semantic consistent grammar trees and reducing parsing ambiguity at parsing stage, to simplifying semantic process at semantic process stage.

为了更好地了解用户使用中文进行数据库查询的句式以及从中抽取一定的语法规则，我们进行了用户使用受限汉语书写数据库查询语句的调查和分析，然后在此基础上我们设计了一种新的文法GWERSC，其非终结符集合不仅采用了现代汉语的文法符号，如名词短语、助词等，同时还采用了与数据库概念紧密相关的实体、属性、联系等语义符号，这样就把现代汉语尤其是受限汉语的知识和数据库知识紧密结合起来，既有利于文法分析又简化了语义处理。

Collocations play an important role in parsing and verbs are the nucleus and precondition of parsing.

搭配是汉语自动句法分析的重要知识源，而动词是句法分析的核心和前提。

It might be an abstract syntax tree, if a 'Node' object is used with each parse rule; it might be a simple list as in the smart ASCII example; it might be a modified string based on concatenations and modifications during parsing; or the return value could simply be 'None' if parsing was done wholly to trigger side effects in parse rules.

东西。如果每个解析规则使用了一个'Node'对象，返回值可以是一个抽象的句法树；也可以如同智能ASCII例子中一样，返回一个列表；也可以返回一个字符串，后者在解析中已经被拼接和修改了；或者如果解析工作主要是通过触发解析规则的负效应完成，返回值可以干脆为'None'。

The analysis result can be applied to disambiguate the high ambiguous problems in parsing process, remarkably improving the performance of parsing algorithm.

创造性地将单词词义分析引入到句法分析当中，利用词义分析的结果对句法分析中难以处理的歧义问题进行排歧，显著地提高了句法分析算法的精度。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
