Adaptive Search Codes for Multimedia Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia data management systems face challenges in effectively providing and searching multimedia data items associated with metadata from different geographical areas and languages, as they lack efficient mechanisms for handling geographic location data and language variations.
Innovation Solution
The system employs a communication interface and databases to receive search requests, identify multimedia data items based on keywords, and transmit results, while utilizing geocoding and language databases to generate and store concatenated search codes that adapt to different languages and locations, enabling efficient search and retrieval of multimedia data across various regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multimedia data items are stored with geographic location data and metadata from different countries, then the system can serve users worldwide, but the search functionality becomes complex due to language variations and different geographical conventions
Solution Approach 1:
The patent introduces search codes as an intermediary element that bridges the gap between users and multimedia data items in different languages and countries. Instead of directly searching in foreign languages, users search using standardized search codes (country codes, city codes, postal codes) that are stored alongside the multimedia data. This intermediary search code system simplifies the search process while maintaining adaptability to different languages and geographical locations.
Solution Approach 2:
The patent changes the search parameter from natural language (which varies by country and language) to standardized codes (country codes, city codes, postal codes). This parameter transformation allows the system to maintain versatility across different languages while reducing complexity, as codes are language-neutral and follow standardized formats.
2Measurement precision
If the system performs reverse geocoding in multiple languages for every multimedia data item, then search accuracy improves, but the processing time and computational resources increase significantly
Solution Approach 1:
The patent performs reverse geocoding and generates search codes in advance when multimedia data items are uploaded or indexed, rather than performing the full reverse geocoding process at search time. The system pre-processes geographic location data into standardized search codes (country codes, city codes, postal codes) and stores these codes with the multimedia data items. This preliminary action significantly reduces processing time during actual search operations while maintaining high search accuracy.
3Loss of information
If the system stores detailed address information and geographic data for all multimedia items, then search completeness improves, but the data storage requirements and system complexity increase
Solution Approach 1:
The patent extracts only the essential geographic information needed for searching (country, city, postal code) and converts it into standardized search codes. Instead of storing complete detailed addresses and all geographic metadata for every multimedia item, the system extracts and stores only the key location identifiers in code format. This extraction approach maintains search completeness for location-based queries while significantly reducing data storage requirements.

AI summary
An apparatus including at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to: maintain a multimedia data item (700) associated with metadata (720), the metadata (720) comprising geographic location data; and perform reverse geocoding from a geocoding database, for determining first address information for the geographic location data, using a first search language. The at least one memory and the computer program code further configured to, with the at least one processor, cause the apparatus to: determine country information from the first address information; retrieve a preferred language based on the country information; perform reverse geocoding from the geocoding database, for determining second address information for the geographic location data, using the preferred language; define search codes (730) using the first address information and the second address information; and store at least one search code (730) to the metadata (720) as a searchable metadata element for subsequent retrieval of the multimedia data item (700) based on the searchable metadata element.
