POS Tagging and Corpus-Based Lexical ... - PAN Localization

Rule-Based Tagger
Generally involves a large database of handcrafted
disambiguation rules (Harris, 1962;
Klein and Simmons, 1963; Green and Robin, 1971)
Based on a two-stage architecture
• The 1 st stage uses a dictionary to assign each
word a list of potential POS
• The 2 nd stage uses a large list of hand-crafted
disambiguation rules to winnow down this list to
a single POS for each word
