计算所汉语词法分析系统ICTCLAS.分词正确率高达97.58%(973专家组评测)，未登录词识别召回率均高于90%，其中中国人名的识别召回率接近98%处理速度为31.5Kbytes/s。ICTCLAS的特色还在于：可以根据需要输出多个高概率结果，有多种输出格式，支持北大词性标注集，973专家组给出的词性标注集合。-Calculate the Chinese Lexical Analysis System ICTCLAS. Segmentation correct rate of 97.58 percent (973 Expert Group on Evaluation), the recall rate of identification of unknown words were higher than 90 percent, of which China s name to identify the recall rate of nearly 98 percent processing speed for 31.5Kbytes/s. Also features ICTCLAS is: can output a number of high probability that there are a variety of output formats, to support the North-of-speech tagging sets, 973 expert group is given a collection of-speech tagging.

在本编译程序中,源语言为PL/0语言,目标语言为假想栈式计算机的汇编语言.PL/0语言是Pascal语言的一个子集，PL/0的编译程序包括了对PL/0语言源程序进行分析处理、编译生成类PCODE代码，并在虚拟机上解释运行生成的类PCODE代码的功能。 　　PL/0语言编译程序采用以语法分析为核心、一遍扫描的编译方法。词法分析和代码生成作为独立的子程序供语法分析程序调用。语法分析的同时，提供了出错报告功能。在源程序没有错误编译通过的情况下，调用类PCODE解释程序解释执行生成的类PCODE代码。 该软件为PL/0语言编译程序,所实现的扩充功能如下: 1.增加单词：保留字 ELSE，FOR，TO, DOWNTO 2.增加运算 +=，-=，++，-- 3.不等号# 改为 4.增加条件语句的ELSE子句 5.扩充语句: ①FOR := TO DO ②FOR := DOWNTO DO 其中，语句①的循环变量的步长为1， 语句②的循环变量的步长为-1。 概述 源文件： *.plo 目标文件： *.COD 实现平台：C＋＋ Builder6.0 -the compiler, the source language of PL/0 language, target language of the imaginary stack of computer assembly language. PL/0 language Pascal language is a subset of, PL/0 compilers including the right PL/0 language source analysis, category PCODE compiler code generation and the virtual machine running on to explain the formation PCODE category code functions.

一个简单的编译器，里面有测试代码，希望对大家有用-A simple compiler test code inside and hope for all of us

这个语法分析器用到的是自顶向下的递归调用的方法，根据Cminus语言的文法规则 的BNF范式编写递归调用的代码，parse方法是程序的入口，它调用的stmt_sequence完成整个语法分析工作，stmt_sequence背后是12个互相调用的方法，它本身也在语法分析的过程中被调用到。 每个方法在最后会返回一个构造好的节点DefaultMutableTreeNode节点t给调用它的方法，然后调用它的方法用这个返回的节点继续构造，最后语法分析完成后会返回一棵完全构造好了的树节点，然后将这个树节点作为根节点生成一个树控件JTree显示到窗体程序上 -CMM 　parser

一般的FOrtran程序编译器只能检查一般的错误，而这个软件可以起到一般编译器不能起到的错误检查、程序优化作用。-Ftnchek (short for Fortran checker) is designed to detect certain errors in a Fortran program that a compiler usually does not. Ftnchek is not primarily intended to detect syntax errors. Its purpose is to assist the user in finding semantic errors. Semantic errors are legal in the Fortran language but are wasteful or may cause incorrect operation. For example, variables which are never used may indicate some omission in the program uninitialized variables contain garbage which may cause incorrect results to be calculated and variables which are not declared may not have the intended type. Ftnchek is written in C. To build ftnchek, you must have a C compiler for the machine on which you wish to build it. The URL for ftnchek s home page is http://www.dsm.fordham.edu/~ftnchek. Source code, binary executables for some platforms, and other information are available there.
