Audience Sentiment Analysis System for Webcast Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audience feedback systems for webcasting are inadequate in providing real-time and accurate sentiment analysis, often relying on unreliable automated techniques or cumbersome manual processes, and fail to effectively engage audiences in providing sentiment feedback during events.
Innovation Solution
A rating-system that allows audience participants to express opinions through thumbs-up/thumbs-down buttons, with sentiment analysis combining and normalizing votes in real-time, providing live and post-event reporting, and allowing event organizers to adjust messaging based on audience sentiment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated sentiment analysis techniques are used, then processing speed is improved, but measurement precision deteriorates due to unreliable automated interpretation of text-based questions and emoticons
Solution Approach 1:
The patent introduces an intermediary sentiment analysis system that acts as a bridge between audience feedback and event content. This system processes sentiment data through multiple techniques including text analysis, emoticon recognition, and pattern matching to generate reliable sentiment indicators that are then fed back to influence event delivery, resolving the contradiction between automated processing speed and measurement precision
Solution Approach 2:
The system implements continuous feedback loops where sentiment analysis results are used to dynamically adjust event delivery. The sentiment indicators generated from automated analysis feed back into the system to modify content presentation, creating a closed-loop control mechanism that improves both processing efficiency and sentiment measurement reliability
2Measurement precision
If manual sentiment processing techniques are used, then measurement precision is improved, but productivity deteriorates due to slow processing speed and human errors
Solution Approach 1:
The patent replaces manual mechanical processing with an automated electronic sentiment analysis system that uses computer algorithms, text processing, and data analysis techniques. This substitution eliminates human errors and significantly increases processing speed while maintaining measurement precision through multiple validation techniques
Solution Approach 2:
The sentiment analysis system performs self-validation and error checking through automated algorithms that cross-reference multiple data sources and sentiment indicators. The system independently processes and validates sentiment data without requiring manual verification, achieving both high precision and productivity
3Measurement precision
If polls and surveys are used to gather audience feedback, then measurement precision is improved, but device complexity deteriorates due to cumbersome survey administration and multiple question formats
Solution Approach 1:
The patent creates a universal sentiment analysis system that handles multiple types of audience feedback (text, emoticons, survey responses, behavioral data) through a single integrated platform. This multi-functional system simplifies complexity by providing a unified interface and processing mechanism for diverse feedback types
Solution Approach 2:
The system merges multiple feedback collection methods including polls, surveys, text analysis, and behavioral tracking into a single integrated sentiment analysis platform. By combining these functions, the system reduces overall complexity while maintaining the measurement precision of individual methods
4Measurement precision
If repeated surveys are conducted throughout an event, then measurement precision is improved, but loss of time deteriorates due to cumulative survey duration and audience fatigue
Solution Approach 1:
The patent implements periodic sentiment sampling at strategically selected intervals during the event rather than continuous surveying. This periodic approach maintains measurement precision by capturing sentiment trends at key moments while minimizing total time loss and audience fatigue through optimized sampling frequency
Solution Approach 2:
The system uses partial surveying by selecting specific representative questions and time points rather than administering complete surveys continuously. This partial action approach maintains sufficient measurement precision while significantly reducing the time burden on participants
Data Source
AI summary
A sentiment analysis computing system includes a storage medium and a processing system. Sentiment input is received from audience members viewing a streamed/webcasted event. The received input is stored to the storage medium. A time slice of the webcasted event is determined and sentiment inputs that are within that time slice are obtained. A sentiment value is calculated for the determined time slice based on aggregated sentiment values. The calculated sentiment value for the time slice is then output by the sentiment analysis computing system.
