Session Indexing for Real-Time Annotation and Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies for managing session content, such as recordings and transcriptions, lack a simple and effective method for users to access, bookmark, and annotate during and after the session, especially in multi-user settings, making it difficult to differentiate contributions and retrieve specific sections efficiently.
Innovation Solution
A computer system executing a session managing process that allows users to bookmark and annotate sessions in real-time, with annotations indexed and stored for easy retrieval, enabling users to create custom perspectives and differentiate contributions, and providing a collective index for searching and reviewing session content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional recording technologies (tape recorder, video recorder) are used to record sessions, then the session content can be stored for later review, but it becomes difficult to find specific sections of interest and laborious to fast forward/rewind through lengthy sessions
Solution Approach 1:
The system creates an index of session content in advance (during or after the session), organizing timestamps and descriptions of key moments before review begins. This preliminary indexing allows users to quickly navigate to specific sections without manually fast-forwarding through entire recordings, directly resolving the time loss problem while preserving full session accessibility
Solution Approach 2:
The patent introduces an intermediary indexing system that sits between the raw recording and the user. This index acts as a mediator, translating the continuous audio/video stream into discrete, searchable segments with metadata. Users interact with the index rather than the raw recording, enabling efficient location of specific sections without direct manipulation of the lengthy session recording
2Adaptability or versatility
If annotations are added to tape-recorded sessions, then additional content can be recorded, but the annotations are not part of the original session and must be recorded separately in written form or on different tapes
Solution Approach 1:
The system merges the annotation storage with the original session recording by associating annotations with specific timestamps in the session data structure. Rather than maintaining separate annotation records or requiring separate physical media, the annotation system is integrated into the digital session file, allowing annotations to be stored and retrieved alongside the original content without additional complexity
Solution Approach 2:
The digital session recording system serves multiple functions simultaneously: it stores the original audio/video content, maintains a searchable index, and accommodates annotations. This multi-functional approach eliminates the need for separate annotation storage systems, as the same digital infrastructure handles all three tasks, thereby reducing overall system complexity while enhancing adaptability
3Loss of information
If conventional transcription methods (voice recognition software or manual transcription) are used, then session content can be converted to written form, but users cannot easily differentiate what each user has said or attribute contributions to the correct user
Solution Approach 1:
The system segments the session content by speaker, creating distinct transcribed portions attributed to each participant. Rather than producing a single undifferentiated transcript, the system divides the transcription into speaker-specific segments, enabling precise attribution of contributions while maintaining complete session content. This segmentation can be achieved through speaker identification algorithms or manual speaker labeling during transcription
Solution Approach 2:
The transcription system applies different qualities or attributes to different portions of the transcript based on the speaker or context. Each transcribed segment carries metadata identifying the speaker, allowing the system to maintain uniform transcription quality while providing localized differentiation. This enables users to attribute contributions accurately without compromising the overall transcription completeness
4Loss of information
If users review entire lengthy sessions to understand the order of speaking, then complete session context is obtained, but the review process becomes very inconvenient or nearly impossible
Solution Approach 1:
The system performs preliminary organization of session content by creating an indexed structure that captures the order of speaking and key moments before review begins. This pre-organized index presents speakers, topics, and timestamps in a structured format, allowing users to understand session context without listening to entire lengthy recordings. The preliminary indexing preserves complete contextual information while dramatically improving review convenience
Solution Approach 2:
The system transforms the one-dimensional experience of listening to a linear recording into a multi-dimensional review interface. Users can navigate the session through multiple dimensions: chronological order, speaker identity, topic categories, and timestamp-based segments. This dimensional transformation allows users to grasp session context through various pathways without being constrained by the linear time progression of the original recording, making lengthy session review feasible and convenient
Data Source
AI summary
A system records a session on a medium, and differentiates the content of the session into a plurality of sub content sessions. The system indexes the plurality of sub content sessions associated with the session, and allows retrieval of at least one of the plurality of sub content session based on the indexing. The system provides a review of the session.
