A memory stores a plurality of data objects and their respective evaluation scores. A processor is configured to update, in response to an update made to a first data object, evaluation values of one or more second data objects linked from at least the first data object, based on the evaluation score of the first data object. In response to a reference request for one data object, the processor determines the evaluation score of the requested data object, based on the evaluation scores of one or more third data objects having a link to the requested data object. |
