Based on an effective clustering algorithm-Affinity Propagation (AP)-we present in this paper a novel semisupervised text clustering algorithm, called Seeds Affinity Propagation (SAP). There are two main contributions in our approach: 1) a new similarity metric that captures the structural information of texts, and 2) a novel seed construction method to improve the semisupervised clustering process...
With Chinese rapid economic and social development, cities are facing with water scarcity and deteriorating water environment, the sewage treatment engineering has become an increasing concern.
