Conversation Highlight Extraction With Linguistic Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conversation summarization techniques face challenges in generating accurate summaries, particularly in unsupervised settings, due to the sensitive nature of conversations and the subjectivity of determining important content, leading to inefficiencies and high costs in data annotation.
Innovation Solution
An unsupervised method for conversation summarization that utilizes a phrase matcher to identify candidate highlights, applies linguistic filtering rules to eliminate false positives, and adds context to generate augmented highlights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a supervised learning approach is used to train summarization models, then the accuracy of meeting summarization may be improved, but the time and cost required for data annotation increases significantly
Solution Approach 1:
The system performs self-service by automatically generating summaries without requiring human annotators. The unsupervised learning model processes meeting transcripts autonomously, extracting highlights and generating summaries that meet user needs without time-consuming manual annotation processes.
Solution Approach 2:
The patent extracts key information from meeting transcripts by identifying and isolating important statements, decisions, and action items. The system extracts relevant content automatically, separating it from unnecessary meeting discussion, thereby eliminating the need for manual extraction through human annotation.
2Measurement precision
If a supervised learning approach is used to train summarization models, then the accuracy of meeting summarization may be improved, but the cost of acquiring and annotating data increases significantly
Solution Approach 1:
The system performs self-service by automatically generating summaries without requiring human annotators. The unsupervised learning model processes meeting transcripts autonomously, extracting highlights and generating summaries that meet user needs without time-consuming manual annotation processes.
Solution Approach 2:
The patent extracts key information from meeting transcripts by identifying and isolating important statements, decisions, and action items. The system extracts relevant content automatically, separating it from unnecessary meeting discussion, thereby eliminating the need for manual extraction through human annotation.
3Measurement precision
If the definition of important content is made more specific to account for sensitive nature of conversations, then the accuracy of highlights may be improved, but the subjectivity and difficulty of determination increases
Solution Approach 1:
The system changes the parameters for identifying important content by using multiple linguistic filters and criteria rather than relying on single subjective definitions. It analyzes sentence structure, keyword presence, and contextual patterns to objectively determine highlight status, reducing subjectivity while maintaining accuracy.
Solution Approach 2:
The system incorporates feedback mechanisms where users can review and provide feedback on generated summaries. This feedback loop allows the unsupervised learning model to iteratively improve its performance by learning from user corrections and preferences, gradually adapting to the specific needs and sensitive nature of different conversations.
Data Source
AI summary
This disclosure describes techniques for generating a conversation summary. The techniques may include processing at least one statement indication of the conversation to determine at least one statement that is a candidate highlight of the conversation. The techniques may further include applying linguistic filtering rules to the candidate highlight to determine the candidate highlight is an actual highlight. The techniques may further include generating the conversation summary including providing the actual highlight as at least a portion of the conversation summary.
