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.
