This book explains the ideas behind one of the most well-known methods for knowledge graph embedding of transformations to compute vector representations from a graph, known as RDF2vec. The authors describe its usage in practice, from reusing pre-trained knowledge graph embeddings to training tailored vectors for a knowledge graph at hand. They also demonstrate different extensions of RDF2vec and how they affect not only the downstream performance, but also the expressivity of the resulting vector representation, and analyze the resulting vector spaces and the semantic properties they encode.

This volume introduces user-interface application integration and examines current problems that ontologies can solve. It details a new way of applying ontologies to system integration and discusses how end-users can benefit from semantic technologies.

The globalization of everyday business and increasing international trade lead to a growing need to improve national and international business collaborations and transactions. They then apply them to build business use application components deployed as web services.
