Clearly, query performance has become a major issue for Semantic Web applications. In his book, Groppe details various aspects of high performance Semantic Web data management and query processing. His presentation to fill the gap between the Semantic Web and database books, which may fail to consider the issue of large-scale data management performance or failure to exploit the special nature of the Semantic Web and query data model. After a general introduction to the relevant standard Semantic Web, it presents a special indexing and sorting algorithms, tailored approach for logical and physical query optimization, the possibility of optimization when using a parallel database technology, today's multicore processors, and a visual query language and embedded?. Groppe mainly targets researchers, students, and developers of large scale Semantic Web applications.
