Google is rolling out an important change to its search engine that has relevance for music artists. It’s called the Knowledge Graph, which is characterised in a blog post by SVP of engineering Amit Singhal as “things, not strings”. The idea being partly to make it easier to drill down for search terms that could have multiple meanings – one click to narrow a ‘Taj Mahal’ search down to the artist rather than the monument, for example. But it also provides more information: summaries, key facts and links. “For example, the information we show for Tom Cruise answers 37 percent of next queries that people ask about him,” writes Singhal. The new features are rolling out initially to US English users of Google, on web and mobile devices.
