TAG is a review platform that shows you recommendations based on your location and inner circle. You can filter by category to view ratings and reviews from people you know. It simplifies content categorization by linking a single tag to multiple relevant subcategories or topics. For instance, the tag "apple" can be associated with subcategories like fruit, tech company, or record label. This simplifies search and retrieval of relevant content. TAG association is useful in social media, e-commerce, and content management systems, helping users discover content aligned with their interests.
