What is Text Info.Management? TIM is concerned with technologies for managing and exploiting text information effectively and efficiently Importance of managing text information The most natural way of encoding knowledge Think about scientific literature -The most common type of information How much textual information do you produce and consume every day? -The most basic form of information It can be used to describe other media of information -The most useful form of information!
