An evidential support system for determining the strength of agreement between a plurality of sets of evidential data comprising an input port for receiving a plurality of sets of evidential data from at least one external source, a data storage device for storing interval data corresponding to a plurality of confidence intervals and correlation value data corresponding to possible values of combinations of pre-determined weighting values, a correlation unit for determining a correlation between entries in the at least two of the plurality of sets evidential data, a comparison unit for comparing the strength of correlations between said entries, the correlation unit being arranged to assign pre-determined weight data to each entry in a set of evidential data and being further arranged to determine intersections between entries the at least two of the plurality of sets of evidential data, the correlation unit being arranged to determine correlation value data based upon the pre-determined weight data assigned to intersecting entries in the at least two sets of the plurality of sets of evidential data, the comparison unit being arranged to receive the correlation value data from the correlation means and to access the interval data stored upon the data storage device and to assign each correlation value datum to a respective credible interval range associated with an interval datum, and the comparison unit being further arranged to compare interval data associated with respective correlation value data in order to determine identifier data indicative of relative belief strengths of the plurality of sets of evidential data. |
