To set the stage: what the ***** is a knowledge graph? It’s basically a big ol’ database of facts, relationships, and concepts that computers use to understand the world around us. Think of it as Wikipedia on juice but instead of being written by humans, it’s generated automatically based on data from various sources like news articles, scientific papers, and social media posts.
Now, common sense reasoning in AI. This is where things get really exciting (or at least, that’s what we tell ourselves). Common sense reasoning involves using logic to make decisions or draw conclusions based on the information available in a knowledge graph. For example: if you know that water boils at 100 degrees Celsius and you have a pot of water on the stove set to high heat, your computer brain can infer that the water is going to start bubbling soon.
But here’s where things get tricky or rather, hilarious. Because computers are notoriously bad at common sense reasoning (just try asking Siri what time it is in New York and you’ll see what I mean). That’s why we need knowledge graphs to help them out. By providing a structured framework for organizing information, knowledge graphs can make it easier for AI systems to understand the relationships between different concepts and draw logical conclusions based on that data.
So how do we build these knowledge graphs? Well, there are a few ways but one popular method is called entity linking. Essentially, this involves identifying entities (like people, places, or things) in text and connecting them to their corresponding entries in the knowledge graph. This can help AI systems better understand context and make more accurate predictions based on that information.
But here’s where it gets really fun because sometimes, computers just don’t get it. For example: if you ask Google Bard “What is the best way to catch a cheetah?” it might respond with something like “The best way to catch a cheetah would be to set up traps or use trained dogs.” But what if you want to actually run faster than a cheetah? Well, that’s where common sense reasoning comes in and unfortunately for Bard, it doesn’t have much of that.
