Information Storage and Retrieval

Fixed structures in data storage and retrieval systems although they help retrieve information, they do not fill the gap between the user knowledge and the information resources in the system database. In the system of storing and retrieving science-oriented information, documents are organized according to the needs of users and each user can have a thesaurus and a set of documents. In this system, user interface and information need, are the cognitive components and this relationship depends on the success in meeting the information need. With the latest findings in the field of data storage and retrieval, the author has also devoted a chapter to examining the growing trend of research in this field. Therefore, the study of this book is recommended to students of knowledge and information science and researchers in the field of information storage and retrieval as well as the knowledge systems and software and systems engineering specialists.
