This book is aimed at providing an overview of several aspects of semantic role labeling. Chapter 2 describes how the theories have led to structured lexicons such as FrameNet, VerbNet and the PropBank Frame Files that in turn provide the basis for large scale semantic annotation of corpora. Chapter 1 begins with linguistic background on the definition of semantic roles and the controversies surrounding them.
Chapter 3 presents the general principles of applying both supervised and unsupervised machine learning to this task, with a description of the standard stages and feature choices, as well as giving details of several specific systems. This data has facilitated the development of automatic semantic role labeling systems based on supervised machine learning techniques. Recent advances include the use of joint inference to take advantage of context sensitivities, and attempts to
