Today we are living in the world where curse of dimensionality is a common problem for applications to deal with. Within the limited resources it becomes infeasible to process such huge volumes of data. So, feature selection remains an effective approach to deal with this issue. It has become a common preprocessing task for majority of domain applications. Here we will discuss only few of domains using feature selection.

4.7.3.1 Text Mining

Text mining is an important application of feature selection. On daily basis tones of emails, text messages, blogs, etc., are generated. This requires their proper processing (e.g. their classification, finding their conceptual depth, developing vocabularies, etc.). Feature selection approach has become very handy in such cases by enhancing the performance of the entire process. Literature is full of the feature selection algorithms meant only for text mining.
