IntroductionPeople need information for various purposes. To achieve this, information is organized so that it can be easily recalled, and information retrieval satisfies the user's information needs. The need for information arises from the awareness that something is missing. In order to create better systems to facilitate user interaction, it is necessary to understand the reasons and methods that users use to satisfy their information needs. This briefing helps the reader understand the definition and importance of information seeking behavior, the assumptions, and factors that influence information seeking. behavior and current patterns of information-seeking behavior. Definition Users develop information needs that represent a gap in the user's current knowledge. Information needs have also been described as an anomalous state of knowledge that needs to be refined (Belik, Oddy, and Brooks 1982) and an incompleteness in the user's image of the world (Taylor 1968, p. 181). These needs are the root of the problem for information-seeking behavior. The concept of need is a mental process that exists only in the user's mind. Information seeking is a fundamental human activity in the model of gathering information and satisfying users' information needs. Information seeking behavior (ISB) can be defined as how a user proceeds in gathering information from recognizing a lack of knowledge to realizing understanding. Searching for information is not a simple action. When trying to find information, users can be described as being in the information search process (ISP). The way they proceed in this search process can be called an information search strategy.
