An extensive review on accessing quality information

The WWW has become one of the fastest growing electronic information sources. In the Web, people are engaging in interaction with more and more diverse information than ever before, so that the problem of information quality is more significant in the Web than any other information system, especially considering the rate of growth in the number of documents. Yet, despite a decade of active research, Information quality lacks comprehensive methodology for its assessment and improvement and a few researches have presented practical way for measuring IQ criteria. This paper attempts to address some of the issues involved in information quality assessment by classifying and discussing existing researches of information quality frameworks. While many of pervious works have concentrated on a dimension of information quality assessment, in our classification has been considered three dimensions: criteria, models and validation methods of the models and criteria. This classification prepares a bed for developing practical and at the same time valid information quality model.
