Why build a knowledge graph with DataStax? DataStax's RAG stack provides a unique approach to knowledge graphs by eliminating the need for a dedicated graph database. Instead, it leveragesAstra DB's vector capabilitiesto store both thegraph structureand vector embeddings in a single system. This...
NASAconnected decades of project data into a knowledge graph called “Lessons Learned Database.” The knowledge graph helped NASA’s engineers uncover trends and apply learnings to avoid repeating past mistakes, saving them over $2 million in the Mission to Mars. Ciscocreated a metadata-driven kn...
This chapter outlines the state of the art of Knowledge Graph technologies by introducing the process of building a Knowledge Graph. We define the following major steps of an overall process model: (1) knowledge creation, (2) knowledge hosting, (3) knowledge curation, and (4) knowledge ...
Once you’ve decided on your use case for your Enterprise Knowledge Graph, there are a few things to keep in mind throughout the build. 1) All knowledge graphs start off with data, 2) Building them will be iterative, and 3) Always build it through the lens of your use case. Avoid ...

To build up a knowledge graph, it's important to extract nodes and the relation between them. There are several unsupervised manners to do the information extraction. On syntactic level, we could leverage part-of-Speech (POS) tags to help us extract this information, or, on semantic level,...
Below is a step-by-step guide to help you build a knowledge map tailored to your organization’s needs. 🗂️ Step #1: Define the purpose and scope Start by defining what you want to achieve with the knowledge map.Are you mapping processes, competencies, or the flow of information?
