The design of question database is an important part of digitized campus construction. In this article, the current problems which has been existed in present intelligent strategies of test paper generating was analyzed, a new model of intelligent test paper was proposed. A new strategy of intelligently generation of test paper was used in this thesis. In order to identify the questions, barcode was...
Traditional grid-density based spatial clustering algorithms divide input data space into partitions with same width and neglect the natural distributing character of initial data space. A new robust spatial clustering algorithm based on optimized-division (OpD-Clus) is proposed in this paper. Spatial data space is divided by hyper-planes which are encertained with axis-paralleled histogram in OpD-Clus...
