Indicative Summaries for Text Message Threads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of mailing lists and discussion groups face difficulty in finding relevant information as current representations require reading multiple postings to understand the content of a thread, with subject lines often not providing a clear description of the discussion.
Innovation Solution
A method and apparatus that extract representative sentences from each text message in a thread based on word overlap with the subject or root message, generating indicative summaries to provide a concise overview of the thread's content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If users read most of the postings in a given thread to gain understanding of the content, then they can obtain complete information, but they waste a significant amount of time
Solution Approach 1:
The patent extracts key sentences from each message in a thread to create an indicative summary. This extraction process identifies and removes only the essential information-bearing sentences while discarding redundant content, allowing users to quickly grasp the thread's main points without reading every message.
Solution Approach 2:
The patent segments the thread content into individual sentences and evaluates each sentence's importance based on word overlap with the subject line. This segmentation allows the system to selectively present only the most relevant sentences in the indicative summary, rather than requiring users to process the entire thread sequentially.
2Ease of operation
If subject lines are used to describe thread content, then the representation is simple and quick to scan, but they rarely give a good description of what is being discussed
Solution Approach 1:
The patent introduces an intermediary indicative summary between the subject line and the full thread content. This summary acts as a mediator that provides more detailed information than the subject line while remaining more concise than the complete thread, helping users make informed decisions about which threads to read.
Solution Approach 2:
The patent performs preliminary analysis of the thread content by calculating word overlap between sentences and the subject line before the user arrives. This preliminary action creates the indicative summary in advance, so when users view the thread list, they immediately see an accurate preview of the content without having to read the entire thread.
3Loss of information
If digests containing actual content of each thread are provided, then users can more easily find topics of interest, but users must still browse the digests containing actual content
Solution Approach 1:
Instead of providing complete digests of thread content, the patent extracts only the most informative sentences based on word overlap analysis. This extraction creates a condensed indicative summary that preserves the essential information while eliminating unnecessary content that users would otherwise need to browse.
Solution Approach 2:
The patent changes the parameter of information density by selectively including or excluding sentences based on their word overlap score with the subject line. This parameter change allows the indicative summary to maintain high information content while reducing the overall volume of text users must scan.
Data Source
AI summary
A method and apparatus are provided for summarizing a text message, such as an email message or a transcribed audio message. A portion of each text message, such as a sentence, is extracted as an indicative summary of the text message based on a degree of overlap of words in the sentence with a set of words, such as words in the message subject or words in a related root message. The extracted portion is based on a score for each portion of the text message, such as a sentence. An interface is also provided for presenting the indicative summaries of a set of related text messages to a user.
