Google’s knowledge graph – a huge project to interconnect the world’s knowledge
Currently, when you perform a search on Google, it simply returns webpages that it thinks provide the most credible and relevant answers to your search. For instance, a search for “holidays in Florida” returns the most closely relevant webpages as below:
Where Google struggles with the current methodology is when one uses a multifaceted question; for example, “Find a holiday for a young family, where the temperature is more than 80 degrees and the price is less than £400 per person”.
The question has at least 5 elements to it. It’s the sort of question you would ask a human retail agent. However, if you asking the same question of Google with its current algorithm, it really can’t come up with anything even remotely useful.
Google sees a major opportunity to change the world using a combination of Artificial Intelligence and the world’s complete knowledge base (see this article on Google’s amazing ambitions in this area – Google Books). It is called the Knowledge Graph and uses AI to run connectors between “entities” (which can be anything from a human to a book to a place).
The clip below shows how it works and what it will do.
