摘要

本文给出了基于a *搜索过程的PCFG解析算法在机器翻译系统中的应用实例。为了提高机器翻译系统Translatica中现有的基于cyc的解析器的性能，我们对其进行了改进，并采用了A*解析算法。

Effective natural language parsing with probabilistic grammars

This paper presents an example of application of a PCFG parsing algorithm based on the A* search procedure in a machine translation system. We modified the existing CYK-based parser used in the machine translation system Translatica and applied the A* parsing algorithm in order to improve the performance of the parser.
