The four main chapters of the book then cover document retrieval from collections and from the Web, information extraction, text categorization, named-entity and coreference recognition, and automatic summarization.
unlike the standard large and comprehensive computational linguistics textbooks (Jurafsky and Martin 2000;Manning and Schütze 1999) and handbooks (Dale, Moisl, and Somers 2000;Mitkov 2003), Jackson and Moulinier's book is concise and focused on the goal of building applications.
