How to improve the accuracy of the concept similarity computation is still an issue needed to be studied further. This paper proposes a new approach which combines concept similarity with the users' individual preference. The personal coefficients trained by artificial neural network are employed to adjust the initial concept similarities to get the actual concept similarities. The experimental results...
Land use change is the most significant aspect in the research field of globe changing. Affected by both of natural and artificial factors, the land use and land resources quality varied continually. Dongguan City where the zone has a typical feature of land use change and significant ecological effects is selected as a case. This paper analyzed the spatial conversion of arable land in Dongguan city...

A case selection algorithm selects representative cases from a large data set for future case-based reasoning tasks. This paper proposes the SRS algorithm, based on similarity-based rough set theory, which selects a reasonable number of the representative cases while maintaining satisfactory classification accuracy. It also can handle noise and inconsistent data. Experimental results have confirmed...
