Summarization as feature selection for text categorization
Aleksander Kołcz, Vidya Prabakarmurthi, Jugal Kumar Kalita · 2001
We address the problem of evaluating the effectiveness of summarization techniques for the task of document categorization. It is argued that for a large class of automatic categorization algorithms, extraction-based document categorization can be viewed as a particular form of feature selection performed on the full text of the document and, in this context, its impact can be compared with state-of-the-art feature selection techniques especially devised to provide good categorization performance. Such a framework provides for a better assessment of the expected performance of a categorizer if the compression rate of the summarizer is known.
