Users express their information needs to the information system through a variety of symbolic processing systems and methods of expression. Eventually the information system can present a final answer to the user’s needs through matching what is presented as a question with the available documents and resources. The purpose of this research is to describe various aspects of information needs.
Design/Methodology/Approach: The present research initially summarized and described the subject of information needs, different types of it and factors affecting it, through reviewing different texts. Then concepts like expression and thought, the interaction between them and the methods of symbolic processing were studied. Moreover this study then explored the subject of expression of information needs, types of questions and issues raised about information systems related to the expression of information needs and the methods of expressing this need. Accordingly, the patterns of information seeking in which the expression of information need is referred to as a component of the model, are reviewed.
Conclusions: This research presents linguistic and psychological as well as some approaches towards storage and retrieval systems for research in the field of information needs, with an emphasis on Persian. These approaches can trigger new research in Library and Information Science in Iran.
