TAILIEUCHUNG - Managing and Mining Graph Data part 21

Managing and Mining Graph Data part 21 is a comprehensive survey book in graph data analytics. It contains extensive surveys on important graph topics such as graph languages, indexing, clustering, data generation, pattern mining, classification, keyword search, pattern matching, and privacy. It also studies a number of domain-specific scenarios such as stream mining, web graphs, social networks, chemical and biological data. The chapters are written by leading researchers, and provide a broad perspective of the area. This is the first comprehensive survey book in the emerging topic of graph data processing. . | 1882 MANAGING AND MINING GRAPH DATA different links the parcnt-chitd -inks document-internal links and reference links cross-document links where the cross-document links are supported by vaiuc matching us-ng IDJDREF in XML.
