在Brill(1994)关于词性标注的开创性工作中,起点是为每个单词分配其最常见的标签。对第一步的扩展是利用词汇上下文(即,字和标点符号)围绕着这个词。这种方法显然可以用于使用块标签将标签排序为更高阶的单元(称为块)。
In Brill's (1994) groundbreaking work on parts-of-speech tagging, the starting point was to assign each word its most common tag. An extension to this first step is to utilize the lexical context (i.e., words and punctuation) surrounding the word. This approach could obviously be used for ordering tags into higher order units (referred to as chunks) using chunk labels.
