The digital information is growing so rapidly in organizations, due to which it's very tedious process to examine some useful information. For this, firstly the authors classify the explosive growth of information in some pattern, rules etc. which represent useful data. The main requirement in classifying is that the pattern which the authors have discovered must be comprehensible and valid. The useful data is intelligently transformed in Knowledge using new analysis techniques. This paper gives a technical overview on the problem faced during knowledge discovery process like uncertainty in rules extraction, classification, data mining process of clustering.
