There are two technologies of the natural language processing. One is called a rule-based method and the other one, a corpus-based method. Although the rule-based method has many advantages, the development of large scale rule set with the wide coverage is very difficult and needs time consuming efforts. This is the reason why corpus-based method exceeds the rule-based method and becomes so popular in natural language processing. The author presents a new algorithm to extracts a grammar rule from the corpus with dependency structure. The algorithm constructs augmented CFG rules automatically and can generate large-scale rule set with wide coverage. The paper presents the details of the algorithm and points out the problems which have to solve in the future. |
