A Trilogy of Webs for Machines

In the coming years we will see a revolution of machine knowledge and abilities which will emerge from different activities and trends in three distinct areas connected to the Internet: The emerging Web of Data, the Web of Services, and a new area, the Web of Identities. These areas, the webs, are about creating accessible and processable semantic knowledge about data, functions and individuals, respectively. They form a knowledge layer for a new era of applications. In this work, we will provide universal definitions for these webs, with a focus on the new introduced Web of Identities, and show how they are related. Furthermore, we outline current activities and trends, and point out the impact of the webs on the future of the Internet based on scenarios exploiting the blended knowledge of these activities.
