Abstract
Systems, methods, and computer products that rank and explain dimensions associated with exceptions in multidimensional data. The present invention assists the data analyst by providing a simplified view of the multidimensional data that enables analysis of the important results of data exception exploration. Further, the preferred embodiment of the present invention incorporates the effect of weighting factors associated with the importance of the data along with an analysis of the numerical contribution from each dimension. The weighting factors may be based on data mining results or may be obtained from the user. This enables data analysts to obtain information about the value of the data that is presented.
Claims24
A computer-implemented method for interpreting and explaining selected exceptions in multidimensional data, at least one dimension being associated with each said selected exception, comprising:
- ranking each said dimension associated with each said selected exception by numerical importance;
- identifying said each dimension that needs to be re-evaluated for possible re-ranking of said each dimension;
- re-ranking said identified dimension, based on at least one weighting factor for said identified dimension;
- and
- presenting said re-ranked each dimension for selection of important views.
A computer system for interpreting and explaining selected exceptions in multidimensional data, at least one dimension being associated with each said selected exception, comprising:
- each said dimension that is associated with each said selected exception and that is ranked by numerical importance;
- said each dimension that is identified when said each dimension needs to be re-evaluated for possible re-ranking of said each dimension;
- said identified dimension that is re-ranked, based on at least one weighting factor for said identified dimension;
- and
- said re-ranked each dimension that is presented for selection of important views.
An article of manufacture comprising a program storage medium readable by a computer and embodying one or more instructions executable by said computer for interpreting and explaining selected exceptions in multidimensional data, at least one dimension being associated with each said selected exception, wherein:
- computer-readable program code ranks each said dimension associated with each said selected exception by numerical importance;
- computer-readable program code identifies said each dimension that needs to be re-evaluated for possible re-ranking of said each dimension;
- computer-readable program code re-ranks said identified dimension, based on at least one weighting factor for said identified dimension;
- and
- computer-readable program code presents said re-ranked each dimension for selection of important views.
