Description: 1. 先打开规则库,读入规则集 (可比较两个规则文件rule1.txt 和 rule2.txt的差异)
2. 选择经过分词和词性标注的文件,进行句法分析
3. 分析结果文件与测试文件在同一个目录下,文件后缀名为 .pcfg
4. 分析结束后,同时产生一个新的规则文件,后缀名为.new, 可以观察规则概率值和期望次数的变化
5. 分析结果逐个以树形图方式显示,如果一个句子有多个结果,在显示框中同时显示。-1. Accounting rules to open, read the rules set (comparable two documents rule1.txt rules and the differences rule2.txt) 2. Word selection and tagging of a document for syntactic analysis 3. Results of the analysis and test document with a document in the directory, documents suffixes called. pcfg 4. After the analysis, while generating a new rule, known as the suffix. new, can observe the rules of probability values and expectations of changes in the number of five. results of the analysis-by-tree approach to show that if a sentence is over, the box shows the same time show.

Description: 概率句法分析器对于统计自然语言处理的很多高层应用,如统计机器翻译、问答系统、信息抽取、文本挖掘等都是至关重要的,直接决定这些应用系统的最终性能。本系统是一个概率型的Chart分析器。系统的分析算法是采用了多种优化策略。分析结果是概率最大的一棵分析树。在概率模型方面,本系统在一定程度上突破了pcfg的上下文无关假设,引入了结构上下文条件,使得分析结果正确率有了明显提高。在使用宾州中文树库进行的实验中,我们的分析器的标记召回率和标记精确率平均在75%-80%左右。在使用一个短句树库进行的实验中,两个指标都在90%以上。概率句法分析既需要建立合理的概率模型,又需要积累树库等语言资源。我们把所做的一点工作进行开放,就是希望抛弃闭门造车的做法,集思广益,推动这个基础领域的发展,使汉语的句法分析尽早实现实用化-probability syntax analyzer for statistical natural language processing of many senior applications, such as statistical machine translation, quiz systems, information extraction, text mining are essential, these applications directly determine the final performance. The system is a probability - based Chart analyzer. Systematic analysis algorithm is optimized using a variety of strategies. Results of the analysis is the greatest probability of a tree. The probability model, the system to some extent breakthrough in the context of pcfg unrelated to the assumption that the introduction of the context of the structural conditions, making results of the analysis accuracy rate has markedly improved.
