Social Sketch Generation via Time-Based Clustering and Expert Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing social networking platforms lack an efficient way to summarize and represent the dynamic nature of social communications over time, failing to capture the essence of fleeting popular topics effectively.
Innovation Solution
The system generates a 'social sketch' by filtering, clustering, and extracting high-quality communications from social networking services, distinguishing between non-expert and expert contributions, to create a snapshot of social communications for a given period, allowing for targeted summaries and evolution tracking of topics over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If social communications are summarized using typical summary methods, then the summary covers the subject matter, but it fails to capture the dynamic nature and fleeting popularity of topics over time
Solution Approach 1:
The patent segments social communications by dividing them into time-based windows and topic-based clusters. This segmentation allows the system to capture dynamic topic evolution over time while organizing communications into manageable groups, resolving the contradiction between capturing temporal dynamics and maintaining system complexity at acceptable levels.
Solution Approach 2:
The patent implements dynamics by creating time-sensitive social sketches that are regenerated for different time periods. The system dynamically adjusts the summary content based on the time window specified, allowing users to explore how topics evolve from fleeting popularity to sustained discussion, thereby capturing the dynamic nature without requiring a permanently complex system structure.
2Loss of information
If all social communications are analyzed and summarized, then comprehensive coverage is achieved, but the system cannot efficiently handle the staggering volume of daily communications
Solution Approach 1:
The patent extracts only the most relevant and representative communications from the vast corpus of social media data. By identifying and extracting high-quality communications that best represent each topic cluster, the system achieves comprehensive coverage of important information without needing to process every single communication, thereby improving processing efficiency while maintaining information completeness.
Solution Approach 2:
The patent changes parameters by adjusting the time window size and cluster selection criteria based on user needs and computational resources. This allows the system to balance comprehensive coverage with processing efficiency by modifying analysis parameters rather than maintaining a fixed, resource-intensive processing regime.
3Measurement precision
If social communications are clustered by topic, then topic evolution can be tracked, but distinguishing between expert and non-expert contributions becomes challenging
Solution Approach 1:
The patent applies local quality by differentiating between expert and non-expert communications within each topic cluster. The system assigns different weights or markers to communications based on the expertise level of the contributor, allowing precise tracking of how both expert and public discourse evolves on each topic without requiring a completely separate analysis system.
Data Source
AI summary
Systems and methods for generating a social sketch from social communications are provided. Unlike a typical summary of a subject (or of multiple subjects), a social sketch represents a “snapshot” summary of the social communications of people during a given period of time. The social sketch is generated by obtaining a corpus of social communications and filtering the social communications according to time. The filtered results are clustered according to the subject matter/topics of the social communications. Selected clusters are identified and the topic, representative high-quality social communications from non-experts and experts are extracted from each of the selected clusters and saved as a social sketch corresponding to the time period.
