1. MODELS OF INFORMATION BEHAVIOR/INFORMATION SEEKING BEHAVIOR
1.1 Introduction of Information seeking
According to Marchionini, information seeking is a "process driven by life itself" (Marchionini, 1995). “A process in which humans purposefully engage in order to change their state of knowledge” (Marchionini, 1995). Information seeking is an essential and ongoing activity where humans seek to address their needs through the information seeking process. In the context of the electronic environment, Marchionini identifies the "problem" as the kernel of information seeking; to address the problem, the seeker engages in search tasks in systems, whose outcomes are organized and contextualized by domains and settings (Marchionini, 1995). Notably, information seeking occurs in a wide range of environments, both online and offline (in earlier formulations, electronic or non-electronic).
1.2 Model of Information Seeking The influence of new technology on information seeking is also providing a new set of alternative models that more accurately describe the information seeking process as a dynamic activity. Models of information seeking attempt to describe the process a user follows to satisfy an information need. The information seeking models in this section focus on the behavior of information seeking activities.
There are a large number of models of information behavior (Fisher et al., 2005). These models demonstrate the difficulty of representing information needs; they also explain how the information seeking process reduces uncertainty regarding the information need. These models are Kuhlthau 's Information Search Process, Ellis ' Behavioral Model of Search, Wilson 's Model of Information Behavior, Sonnenwald 's Information Horizons, Allen’s Information Tasks (1996) and others.

According to David Johnson (1997), theoretical models of information seeking must address three key issues. First, models should
