Overlapping Transcript Segmentation for Coherent Summaries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transcript summarization methods often result in summaries that are either overly long, unclear, or not comprehensive, requiring excessive processing and memory resources, especially when dealing with lengthy transcripts.
Innovation Solution
Implementing a system that segments transcripts into overlapping portions, where each portion overlaps with at least one other portion, allowing for comprehensive summaries to be generated efficiently with reduced resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transcript is processed as a single large unit, then the summary can capture overall context, but the processing and memory requirements become excessive
Solution Approach 1:
The patent divides the transcript into multiple segments of manageable size, where each segment can be processed independently. This segmentation allows the system to maintain comprehensive context across the entire transcript while reducing the processing and memory requirements for any single operation, as each segment can be handled with standard processing capabilities.
Solution Approach 2:
The patent implements a hierarchical summarization structure where summaries of individual segments are generated first, and then these segment summaries are used to create an overall transcript summary. This nested approach allows the system to build up comprehensive context from smaller units, maintaining reliability while controlling resource usage at each level of the hierarchy.
2Device complexity
If the transcript is segmented into non-overlapping portions, then processing resources are reduced, but context continuity and coherence are lost
Solution Approach 1:
The patent merges overlapping portions of the transcript into a unified structure where adjacent segments share common content. This merging approach allows the system to reduce processing resources by avoiding redundant processing of the same content while maintaining context continuity through the overlapping regions that bridge different segments.
Solution Approach 2:
The patent performs preliminary actions by identifying and marking overlapping portions before the actual summarization process. This preliminary identification allows the system to prepare the transcript structure in advance, ensuring that context continuity is preserved through the overlapping regions while optimizing processing resources by knowing in advance which portions need to be processed multiple times for context preservation.
3Reliability
If the summary is generated from the entire transcript at once, then comprehensive coverage is achieved, but the summary becomes overly long and unclear
Solution Approach 1:
The patent segments the transcript into smaller units and generates summaries for each segment separately. These segment summaries are then combined to form the overall summary, which maintains comprehensive coverage of the entire transcript while keeping each individual summary segment concise and readable, improving ease of operation for users.
Solution Approach 2:
The patent applies partial action by generating summaries for only the necessary portions of the transcript (the overlapping segments) rather than processing the entire transcript uniformly. This partial approach produces comprehensive coverage through the overlapping regions while avoiding the excessive length that would result from processing every portion equally, thereby improving readability.
Data Source
AI summary
In some implementations, a device may obtain a transcript that includes a plurality of utterances. The device may determine that the transcript includes a quantity of tokens that is greater than a threshold quantity of tokens, wherein each token of the quantity of tokens corresponds to a word or a portion of a word included in the plurality of utterances. The device may generate a plurality of overlapping transcript portions, wherein each transcript portion of the plurality of overlapping transcript portions overlaps with at least one other transcript portion of the plurality of overlapping transcript portions, and wherein each transcript portion ends at an end of an utterance of the plurality of utterances. The device may generate a transcript summary based on the plurality of overlapping transcript portions.
