Sentiment Mapping for Media Content Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of traditional and new media in advertising campaigns often leads to 'advertising dissonance' due to conflicting sentiments between the media content and advertisements, reducing user enjoyment and advertisement effectiveness.
Innovation Solution
Creating a 'sentiment map' that evaluates and delimits segments of media content items based on sentiment states, considering video, audio, metadata, and social responses, and personalizes the evaluation based on user preferences to match advertisements with favorable content segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If advertisements are placed in traditional media (television, magazines), then broad audience reach is achieved, but advertising effectiveness is reduced due to advertising dissonance from conflicting sentiments
Solution Approach 1:
The media content is segmented into multiple sentiment segments based on sentiment analysis. Each segment is characterized by specific sentiment states (e.g., happy, sad, exciting, funny) and temporal boundaries. This segmentation enables selective advertisement placement in segments with compatible sentiments, avoiding advertising dissonance while maintaining broad reach across different content types.
Solution Approach 2:
Different quality attributes (sentiment characteristics) are assigned to different segments of the media content. Instead of treating the entire content uniformly, the system identifies specific temporal segments with distinct sentiment profiles and matches advertisements to segments with compatible local qualities, thereby improving advertising effectiveness without sacrificing overall reach.
2Reliability
If sentiment analysis is performed on media content to prevent advertising dissonance, then advertising effectiveness is improved, but system complexity increases due to multiple evaluation parameters
Solution Approach 1:
A sentiment analysis system acts as an intermediary between the media content and advertisement placement decisions. This intermediary component analyzes video, audio, and metadata to generate sentiment segments, which then guide advertisement selection and placement. By introducing this specialized intermediary module, the system achieves improved advertising effectiveness without significantly complicating the overall architecture, as the sentiment analysis function is encapsulated in a dedicated component.
3Measurement precision
If multiple parameters (video, audio, metadata, social responses) are evaluated for sentiment analysis, then sentiment accuracy is improved, but processing time and computational resources increase
Solution Approach 1:
Sentiment analysis is performed in advance of advertisement placement decisions. The media content is pre-processing into sentiment segments with assigned sentiment states and temporal boundaries before advertisements need to be matched. This preliminary action allows the system to maintain high sentiment accuracy through comprehensive multi-parameter evaluation while reducing real-time processing requirements during advertisement placement, as the heavy lifting of sentiment analysis has already been completed.

AI summary
A media content item is evaluated for its “sentiment states.” That is, segments of the content item are determined to be, for example, “happy,”“exciting,”“sad,”“funny,” and the like. A “sentiment map” is created that delimits segments of the content item and contains the sentiment-state keywords associated with the segments. Some maps include an amplitude for each assigned sentiment keyword and a confidence value for the segment delimitation and for each keyword. As an exemplary use of the sentiment map, an advertisement broker matches the sentiments of his advertisement offerings with segments of a content item in order to place appropriate advertisements at times when they would be most favorably received. In another example, a recommender system recommends to a user a content item whose sentiment map compares favorably to that of a content item already enjoyed by the user.
