Importance Of Information Retrieval System

1. Introduction:

Information and knowledge are basic inputs to human growth and socio-economic development. The organisation of thoughts and ideas by the generators of information involves intellectual organisation. Over the last centuries, information available in documentary form has grown in volume, variety and forms. To facilitate access to them, secondary tools and techniques are developed involving intellectual organisation of such information and knowledge. So intellectual aspects and fundamental aspects of organisation are important and its implications in Information Storage and Retrieval Systems is crucial. If the concept ‘intellectual organisation of information’ is examined from a broader perspective, i.e. almost from the generation

In fact these two intellectual activities determine the search strategy to a large extent to obtain optimum results. However, the nature of computerised indexes varies greatly and searchers will get successful results if they recognise some of their inherent strengths and limitations. Generally speaking however, there a number of features those are common to all information retrieval systems, including CD-ROM based systems, the Internet, Online search services, Document management systems, and OPACs. There is a trend in using all these information networks or media by all kinds of users that include novices, domain experts who constantly use IR systems and are familiar with their facilities and functions, occasional users who may depend upon information intermediaries, and other type users who have special needs. Information managers and intermediaries, who do searches on behalf of all categories of users, are expected to be expert users of IR systems. They must work with the users, understand their specific needs and do the search in collaboration with users, reviewing the results of retrieval at every search stage to get maximum results.

11. Areas of Current Research in Information Retrieval Systems:

Active research efforts are pursued to refine or develop efficient information retrieval systems all over the world. The primary purpose of all these efforts is to get the best results for users. System developers and suppliers are striving to offer a best software package or a service. The information researcher is also equally concerned to develop the best retrieval system. The directions, these research activities are taking, may be summed up as given below:
