TLDR
Several typical models of three kings of tagging are introduced in this article: rule-based tagging, statistical approaches and evolution algorithms, and the advantages and the pitfalls of each typical tagging are discussed and analyzed.Abstract:
In natural language processing, a crucial subsystem in a wide range of applications is a part-of-speech (POS) tagger, which labels (or classifies) unannotated words of natural language with POS labels corresponding to categories such as noun, verb or adjective. Mainstream approaches are generally corpus-based: a POS tagger learns from a corpus of pre-annotated data how to correctly tag unlabeled data. Presented here is a brief state-of-the-art account on POS tagging. POS tagging approaches make use of labeled corpus to train computational trained models. Several typical models of three kings of tagging are introduced in this article: rule-based tagging, statistical approaches and evolution algorithms. The advantages and the pitfalls of each typical tagging are discussed and analyzed. Some rule-based and stochastic methods have been successfully achieved accuracies of 93–96 %, while that of some evolution algorithms are about 96–97 %.read more

Transformation-Based Learning in the Fast Lane
Grace Ngai,Radu Florian +1 more
TL;DR: This paper presents a novel and realistic method for speeding up the training time of a transformation-based learner without sacrificing performance and shows that this system is able to achieve a significant improvement in training time while still achieving the same performance as a standard transformation- based learner.
