| 摘 要： | 领域现象术语常常是复合型短语,很难根据局部上下文特征用传统的机器学习方法来抽取.为此,文中提出了一种领域现象术语的抽取方法.该方法首先用基于上下文的方法抽取得到分隔符集,然后结合分隔符集和上下文术语用改进的NC -value算法进行候选领域现象术语抽取,最后在候选领域现象术语中过滤掉名词性术语,进而得到最终结果.实验表...

| Abstract: | As domain-specific phenomenal terms are usually compounds that are difficult to extract according to local context features via the traditional machine learning methods,a novel extraction method is proposed.In this method,first,the context-based method is employed to extract the separator set.Then,with the combination of the separator set and context terms,the improved NC-value algorithm is used to extract candidate phenomenal results.Finally,nominal terms are filtered out from the candidate phenomenal term... |
