Abstract

For better retrieval, classification and indexing are the key factors. To serve better users there should be some criteria. The most popular criteria known are recall and precision. But these two are not totally accepted and respected in application. Uncertainty and giving more respect to information technology at the expense of information system management are the main problems. Although information retrieval includes many elements such as modality, document classification and categorization, system architecture, user interfaces, data visualization, filtering, language and behavioral sciences, communication in a good environment covers all of them. For better communication, a classifier/ indexer must avoid taking false direction, to be frank and careful not to use ambiguous terms, and must provide sufficient cross-references their indexing. Good questioning and saying no when it should be said is regarded as a kind of filtration of the environment from noises.
