Part-of-Speech (POS) Tagging
摘要
Part-of-Speech (POS) Tagging is the foundation of text processing in NLP. This chapter describes how it relates to NLP and NLU (Natural Language Understanding). Various types and algorithms for POS Tagging include Rule-based POS Tagging, Stochastic POS Tagging, and Hybrid POS Tagging with Brill Tagger and evaluation schemes. This chapter also serves as the conceptual basis for Workshop#3—Part-of-Speech using Natural Language Toolkit in Chap. 12 .
