Knowledge Graphs
Knowledge Graphs are like smart digital maps that show how different pieces of information are connected to each other. Think of it as an advanced version of connecting the dots, where computers can understand relationships between data points, similar to how humans connect ideas. Companies use Knowledge Graphs to organize large amounts of information in a way that makes it easier to find connections and patterns. For example, Google uses a Knowledge Graph to improve search results by understanding how topics are related to each other. This technology helps companies make their AI systems smarter by giving them a better understanding of how different pieces of information relate to each other.
