Instant Messaging Chat Record Search via Content Summary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current instant messaging (IM) systems cannot search for non-text information such as URLs, photos, or audio/video files in chat records, as they are saved in plain text format, making it difficult for users to retrieve these items by keyword search.
Innovation Solution
The method involves acquiring a content summary of non-text information when an instant message contains it, saving the message as a data object comprising both the non-text information and its summary, allowing users to search by typing keywords from the summary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If non-text information (URLs, photos, audio/video files) is saved in plain text format, then the storage structure remains simple, but the ability to search for non-text information is lost
Solution Approach 1:
The patent segments non-text information into two parts: the original non-text data (URLs, photos, audio/video files) and extracted text content (titles, descriptions, keywords). This segmentation allows the system to maintain simple plain text storage for the original data while adding searchable text attributes separately, thus improving search capability without significantly increasing overall system complexity
Solution Approach 2:
The patent introduces text content (titles, descriptions, keywords) as an intermediary between the non-text information and the search function. This intermediary layer enables users to search for non-text information using text keywords without requiring complex direct indexing of binary data, thereby enhancing searchability while keeping the storage structure relatively simple
2Ease of operation
If content summary is added to non-text information, then search functionality is improved, but storage space consumption increases
Solution Approach 1:
The patent applies partial action by extracting only essential text content (titles, descriptions, keywords) from non-text information rather than storing complete content. This selective extraction provides sufficient search capability while minimizing the additional storage space required, avoiding the excess of storing full content
Data Source
AI summary
A method for saving chat records of instant messaging (IM) includes when an instant message transmitted or received by an IM chat window comprises non-text information, acquiring a content summary of the non-text information, and saving the instant message, and saving the non-text information as a data object comprising the non-text information and the content summary of the non-text information.
