Development of IR systems: New direction

摘要

The paper addresses a question of improving the quality of satisfaction of information need (IN) through the use of information retrieval (IR) systems. This improvement is achieved by more fully taking into account the characteristics of IN when developing IR systems. For this reason the characteristics of IN are investigated very carefully and on the basis of this analysis the paper proposes a new instrument in IR systems which takes into account different components of IN. Special attention is paid to the practical implementation of such IR systems. Using the goal component of IN as an example the paper demonstrates how to take this component into account in the process of IR system functioning, namely by using a list of tasks and requirements. It is shown that during the implementation of this list several problems have to be addressed and the paper discusses some possible solutions. The suggested methods and approaches are easily adaptable to any IR system and their realization is quite simple. The paper stresses the importance of this new direction in developing IR systems.
