It's been ten years since Google (now a child of holding company Alphabet) coined the term "knowledge graph" and described (in general terms) how their knowledge graph worked. And it's been over 20 years since Tim Berners-Lee, James Hendler and Ora Lassila published their first article to describe the semantic web they envisioned. Many knowledge graphs have been built using the semantic standards the W3C subsequently put in motion a decade or more ago. It's interesting to ponder what's happened since. Over the past decade, Alphabet has grown consistently to become one of the top six companies globally to achieve a market capitalization (total stock value of shares outstanding) of over $1 trillion.
