Text Summarization
摘要
This chapter is concerned with the text summarization task in terms of its function, methods, and implementation. Text summarization is defined as the process of rewriting briefly the contents of an entire text. Automatic text summarization is viewed as selection and extraction of essential parts of a text. In recent research, this task is mapped into an instance of text categorization that classifies each sentence or each paragraph into summary or non-summary. In this section, we describe the text summarization as the additional task to text classification and clustering that are covered in the previous parts.
