The semantic web is an extension of the current web that aims to make online information more understandable for computers. By using structured data and standardized formats, it allows machines to interpret the meaning of information, rather than just displaying it. This helps in connecting related data across different websites, making it easier for users to find what they need. For example, when you search for a restaurant, the semantic web can help link information about menus, reviews, and locations from various sources. This interconnectedness enhances the user experience by providing more relevant and comprehensive results tailored to individual needs.
