An information storage and retrieval system (ISRS) is a network with a built-in user interface that facilitates the creation, searching, and modification of stored data. An ISRS is typically a peer-to-peer (P2P) network operated and maintained by private individuals or independent organisations, but accessible to the general public. Computers and data processing techniques have made possible the high-speed, selective retrieval of large amounts of information for government, commercial, and academic purposes. There are several basic types of information-storage and-retrieval systems. Document-retrieval systems store entire documents, which are usually retrieved by title or by key words associated with the document. In some systems, the text of documents is stored as data. Characteristics of an ISRS include lack of centralization, graceful degradation in the event of hardware failure and the ability to rapidly adapt to changing demands and resources. The lack of centralization helps to ensure that catastrophic data loss does not occur because of hardware or programme failure, or because of the activities of malicious hackers. Graceful degradation is provided by redundancy of data and programming among multiple computers. The book provides coverage of all of the major aspects of information retrieval and has sufficient detail to allow students to implement a simple information retrieval system.…
