tudásgrafikon

A tudásgrafikon, or knowledge graph, is a structured representation of information that describes real-world entities and their relationships. It is essentially a network of interconnected data points, where nodes represent entities such as people, places, or concepts, and edges represent the relationships between them. For example, a knowledge graph might connect the entity "Paris" with the entity "France" via the relationship "capital of."

The primary purpose of a knowledge graph is to enable machines to understand and reason about information in a more human-like way. By organizing data into a graph structure, it becomes easier to discover hidden connections, infer new facts, and provide more contextually relevant answers to queries. This is achieved through the use of ontologies and schemas, which define the types of entities and relationships that can exist within the graph.

Knowledge graphs are used in a wide variety of applications. Search engines, like Google, utilize them to provide richer search results, offering direct answers and related information. Virtual assistants, such as Siri and Alexa, leverage knowledge graphs to understand user commands and retrieve accurate information. Furthermore, they are employed in fields like scientific research for data integration and discovery, in e-commerce for product recommendations, and in finance for fraud detection. The ability of knowledge graphs to represent complex relationships and facilitate semantic understanding makes them a powerful tool for organizing and utilizing information in the digital age.
