Abstract:
This paper presents the experimental evaluation study of information retrieval (IR) interaction for a user interface redesign of an online WWW-based IR system and discusses its implications. The goal of the study is to set up a methodological framework in order to investigate if the user interface provided sufficient support in order to conduct an information seeking behavior. In IR interaction, the user interface is the primary mechanism and serves as a link or a communication channel between the user and the computer (system). The focus of user interface design process is on who users are and what the tasks are. Recent studies show that when the end-users are given more instructions and more control over their searches, this affects their satisfaction and performance in a positive way. Throughout the study, it is concluded that when designing a user interface, decisions about the user preferences, user satisfaction, user tasks, user behavior and user requirements should be considered. It is noted that the results and the following conclusions mainly concerns computer science domain, but the implications drawn could represent important factors to be considered for IR design in general. Some factors emerged when examining the user background preferences, user satisfaction and user requirements. The task environments (work-task, information seeking task and search task), the users specific goals and tasks, the users information seeking behaviour, the use of an IR system and its components, including the user interface are some of the levels of work that must be understood in order to understand information seeking in context.
3 things that I've learned:
- Interaction in an IR system is important and can be thought of as being the level of control and support in the decision making of the various information seeking tasks.
- In user interface design process, the focus is on who the users are and what the tasks are. The task of information seeking is complex, and may vary from finding specific information through query formulation to a browsing activity involving exploring the database or information space.The main function of the system is to support the human user in her task(s). This task could be some activity that involves gaining a particular goal or purpose. Support should be designed to provide the user with the necessary assistance in gaining her goal. Generally, the user interface of an IR system has the task of guiding, supporting and transforming user's information problems or needs.
- The user interface can be divided in 2 parts: the interaction components and the development of interface software. The interaction component deals with how the user interfaces works and its behaviour in response to what the user does while performing a task. The interface software deals mainly with the implementation of the code for the interaction component.
Applications/Implications:
It is important that we consider the user interface of an IR system to improve the information seeking behavior of a user. As an information seeker, the interface and visualization of an IR system is one of the main factors that I consider. If the interface is user-friendly and appealing, it will be easy for us to search and find what we are looking for plus satisfaction on the part of the user will be achieved. Now, to help promote user interface design in an IR system, what I can do is to make comment and suggestion on the IR system of a site that I visited that I think does not contribute to the fast information seeking. In that way, I can help the developers know and may consider this to improve their system.
