Image Tag Generation via Multi-Source Data Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image search technologies lack the ability to accurately identify and suggest images based on the subject or topic of an image, often providing irrelevant textual captions and related search suggestions that do not align with the image content.
Innovation Solution
A system that generates image tags by analyzing data from multiple sources, including user profiles and session logs, to provide relevant textual descriptors for images, which can be used to enhance image search and discovery by indicating the subject, content, and categories associated with the images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional search engines use textual query suggestions based on session logs, then search refinement is enabled, but image subject identification capability is lost
Solution Approach 1:
The system performs preliminary analysis of image data from multiple sources (user profiles, session logs, image metadata) to generate image tags before they are needed for search operations. This pre-computation enables rapid retrieval and accurate image subject identification during actual search operations without real-time processing delays.
Solution Approach 2:
Image tags serve as an intermediary between the image content and the search query system. These tags bridge the gap between visual image data and textual search operations, enabling the search engine to understand and retrieve images based on their subject matter rather than relying solely on user-generated text descriptions.
2Measurement precision
If user-generated tags are required for image description, then image search accuracy improves, but user effort and time increase
Solution Approach 1:
The system performs self-service by automatically generating image tags without requiring user intervention. It analyzes image data from multiple sources including user profiles, session logs, and image metadata to autonomously create accurate tags, eliminating the need for users to manually tag images while maintaining high description accuracy.
Solution Approach 2:
The manual mechanical process of user tagging is replaced with an automated computational system that analyzes multiple data sources to generate tags. This substitution eliminates the need for human users to manually describe images, freeing up user time while maintaining or improving tag accuracy through multi-source data analysis.
3Reliability
If image tags are generated in real-time during search, then search relevance improves, but system response time decreases
Solution Approach 1:
Image tags are generated in advance during an offline preprocessing phase before search operations occur. This preliminary action ensures that when users perform searches, the system can quickly retrieve pre-generated tags without real-time computation delays, maintaining both high search relevance and fast response times.
Solution Approach 2:
The system uses periodic batch processing to generate and update image tags from multiple data sources at scheduled intervals rather than continuously. This periodic action allows the system to maintain up-to-date tags for search relevance while avoiding the performance degradation that would result from continuous real-time processing during user searches.
Data Source
AI summary
The technology described herein provides an efficient mechanism for generating image tags. Image data from a plurality of sources may be analyzed to identify relevant text items from the aggregated data. The relevant text items may be keywords describing a subject of an image, an entity of an image, a location of an image, or the like. From the aggregated image data, one or more image tags may be generated and stored as an offline dataset with an image identifier. Upon detecting a prompt such as a user issuing a search query for an image, the image identifier is used to perform a look up of the image and associated image tags to be provided.
