WordNet使用方法

在WordNet中有词语的各种信息，定义、同义、上位、下位、实例、包含等等关系的词集，通过调用相应方法可一一获取，然后进行同义词计算、类别划分等操作。源码的main()函数在wn.c文件中。注意：若在windows环境下调用，则需要在wn.h和wnutil.c文件首行添加 #define _WINDOWS 123 宏定义，否则编译报错。

若在.cpp文件中调用这些函数，则需要将string类型的字符串转换成char数组类型，再传入,main()函数如下

main(int argc,char *argv[]){char *temp,*temp1;if (wninit()) {// open database display_message("wn: Fatal error - cannot open WordNet database\n");exit (-1);}/**********************输出同义词、上位词等**********************/char conv[WORDBUF];string str = "God";char *word = (char *)str.c_str();sprintf(conv,"%s",word);printHype(conv,NOUN);}
