As someone who enjoys exploring and learning about new fields, I often lack a curriculum of learning materials. To solve that problem, I'm parsing wikipedia to create a knowledge graph composed of "concepts" linked to each other. Every "concept" has some prerequisite of other "concepts", say, in order to learn differential equation I need to first learn about calculus, etc. Therefore, if I were to learn about self-driving cars, I can mark the starting point (concepts I already know of) and the target (most important 50 concepts for self-driving car), and the graph would give me the best path to achieve my target. Therefore, I can be self-guided in my learning with the help of a knowledge graph similar to technology tree in games. Let me know what you think!
