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.

Ontology-based Application Integration introduces UI-level (User Interface Level) application integration and discusses current problems which can be remedied by using ontologies. It shows a novel approach for applying ontologies in system integration. While ontologies have been used for integration of IT systems on the database and on the business logic layer, integration on the user interface layer is a novel field of research. This book also discusses how end users, not only developers, can benefit from semantic technologies. Ontology-based Application Integration presents the development of a software framework including a detailed ontology about user interfaces and interactions. This includes a running case study of a real world integrated emergency management system. The last section of this book discusses useful features that can be built on top of the framework for improving the user experience with future integrated information systems. Ontology-based Application Integration is designed as a reference book for practitioners and researchers who understand and work with the principles of applying semantic web technologies to a software engineering problem. This book will also make an excellent reference or secondary text book for advanced-level students concentrating on computer science.

E-business integration is a vision we have developed over a long period of time. As we have worked in business practice for many years prior to and in parallel with our academic research, we have always thought of such - tegration not only as an intellectual challenge but also as a real business tool. Consequently, when we started our project on Ontologies-based R- onciliation for Business Integration (ORBI) in 2004, not only pure science but also business objectives were at the center of our research. We were very happy to be able to form a project consortium that consisted not only of renowned researchers but also of experienced business practitioners from a range of companies. Each played a specific role – as user, provider or co-developer of the application components that are based on the me- ods we have developed. So may this book find its way not only to the desks of researchers and students, but also into the offices and minds of business practitioners worldwide who are dealing with the challenge of integrating their business processes, applications and information. This book is, in the most general sense, about understanding each other – that is, what we do and think. Needless to say, within the project itself, and its environment, we had many opportunities to apply this underlying philosophy. In the end, the results prove it was worth the effort.
