Bosch Semantic Stack Tools

Digital twins are digital representatives of vehicles or machines as well as their components and parts. A digital twin is often created during product development and accompanies its physical counterpart throughout its life cycle. Depending on the company, thousands and thousands of digital twins are "born" every day. Bosch provides the Digital Twin Registry – a digital phone book in which millions of twins can be quickly identified and retrieved for their creation, assignment, storage, and deletion.

Each digital twin consists of several aspects. They group data such as faults, master data, or maintenance history. Each aspect is assigned an aspect model that defines the semantics and can be used for numerous use cases. Depending on the level of complexity of the data, the creation of aspect models requires knowledge and time. Therefore, the Aspect Model Catalog acts as a growing recipe book from which the appropriate aspect models can be downloaded and adapted as well as fed back into the community.

Knowledge graphs represent and analyze relationships between objects. Knowledge layers, in turn, are the functional implementation of this novel technology, with individual graphs as the "output". To make them usable, Bosch is developing a comprehensive set of functions for creating and managing a knowledge layer. It not only serves to detail a knowledge layer, but also supports the management of the system, which is constantly growing with each use case or new data source. The technology can be established in your company regardless of time or personnel capacities.
