Hierarchical Tagging for Digital Content Retrieval

The system performs preliminary action by automatically analyzing digital content and generating tags before the user needs to search. Image and video files are processed in advance to extract visual, audio, and contextual information, creating a searchable index of tags associated with each media file. This preliminary tagging enables rapid retrieval without requiring manual review of each file during the search process.

The patent introduces tags as an intermediary between the user's search query and the actual digital content. Instead of directly searching through files, the system uses tags as a mediating layer that translates user requests into searchable attributes. Tags serve as the intermediary structure that connects search criteria with corresponding media files, enabling efficient retrieval without manual inspection of each file.

The patent replaces the mechanical manual review process with an automated computer-based tagging system. Instead of users mechanically reviewing each file to identify relevant content, the system automatically analyzes media files and assigns tags based on extracted features. This substitution maintains search accuracy through automated feature extraction while eliminating the time-consuming manual review process.

The system performs self-service by automatically generating and maintaining its own tag index without requiring user intervention. The automated tagging process continuously processes new media files and updates the search index independently, providing accurate search results without requiring users to manually tag or review each file. This self-service mechanism maintains precision while saving user time.

The patent applies segmentation by dividing the search process into multiple hierarchical levels of tags. Instead of a single flat search interface, the system organizes tags into categories such as visual features, audio characteristics, temporal information, and contextual metadata. Users can navigate through these segmented categories to construct complex search queries, enabling sophisticated filtering without manual frame-by-frame review of each media file.

The system adds another dimension to the search process by introducing multiple levels of tag hierarchy. Rather than searching through files directly, users navigate through organized tag categories that provide structured filtering dimensions. This dimensional organization enables complex event search by combining multiple tag criteria across different dimensions, significantly reducing search time compared to conventional flat search functions.
