#4590 Knowledge Graph: Thomas Edison and Nikola Tesla Patents #4590  The following web page lists all of Thomas Edison's and Nikola Tesla's patents: https://en.wikipedia.org/wiki/List_of_Edison_patents and https://en.wikipedia.org/wiki/List_of_Nikola_Tesla_patents . How can I create a knowledge graph of his patents and use it to identify patterns of invention. Deconstructing tabular historical data into a high-density, semantic graph database is an exceptionally powerful approach for identifying structural trends in innovation. By treating patents as a networked canvas of inventors, temporal sequences, and technological subsystems, you can transcend basic chronological lists and reveal the systemic archetypes of how Edison and Tesla built their intellectual empires. Here is a step-by-step engineering blueprint to design, populate, and analyze a patented knowledge graph using Neo4j and Cypher . Phase 1: Semantic Data Modeling (Ontology) To capture the underlying mechanics of ...

#4589 Knowledge Graph: Music Chord Progressions

#4589 Knowledge Graph: Music Chord Progressions #4589  Describe a knowledge graph of possible chord progressions and what it could be used for Imagine mapping out the entire universe of music, where every chord is a destination and every transition is a highway. That is essentially what a knowledge graph of chord progressions is. By representing musical harmony as a network of interconnected concepts, we can unlock a whole new way of analyzing, teaching, and creating music. Here is a breakdown of what this knowledge graph looks like and exactly how it can be used. The Anatomy of a Chord Progression Knowledge Graph In graph theory, a knowledge graph consists of nodes (the entities) and edges (the relationships between them). For music theory, it breaks down like this: 1. The Nodes (The "What") Chords: The core building blocks (e.g., C_maj7 , D_min7 , G^7 ). Scale Degrees / Roman Numerals: Abstracted representations of chords independent of key (e.g., I , ii , V^7 ). This ...
