英文摘要
Spatial clustering is an important topic in knowledge discovery research. It is to partition similar data objects into the same group (called cluster) based on their distance, density and reachability in space. It can be used to find natural clusters, to identify hot spots, and to partition an area based on utility. Ignoring domain knowledge and users' requirements during the spatial clustering can lead to useless and distorted clustering results. However, most existing clustering methods do not consider them during the clustering process, which prevents users from precisely describing their goals and understanding the results. Although some methods consider constraints, they only consider sharply limited knowledge concerning the domain and the users.
