Solution Overview

Problem

Existing systems lack efficient methods for determining and presenting relevant message destinations in information-sharing services when replying to threads, especially in document management systems integrated with social networking services.

Innovation Solution

An information processing apparatus and method that extracts and displays threads relevant to the user's participation in a destination group, using APIs to obtain thread information and present it as potential message destinations, facilitating easy selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the system displays all available threads as message destinations, then the user has complete information to choose from, but the user interface becomes complex and overwhelming

Engineering Contradiction:
Improvethread information completenessVSAvoiduser interface complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent extracts only the most relevant threads from the complete set of available threads and presents them to the user. The system identifies threads based on relevance criteria (such as recent activity, user participation, or contextual importance) and displays only these selected threads as destination options, rather than showing all possible threads. This extraction approach maintains information quality by prioritizing relevant data while reducing interface complexity by filtering out less important options.

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If the system automatically selects message destinations based on user history, then message transmission efficiency improves, but the system loses flexibility in user choice

Engineering Contradiction:
Improvemessage transmission efficiencyVSAvoiduser choice flexibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary actions by automatically analyzing user history and thread relevance to pre-select probable message destinations before the user needs to send a message. When the user initiates a message composition, the system has already prepared and highlighted the most likely destination threads based on past behavior patterns and contextual relevance. This preliminary preparation speeds up the messaging process while still allowing the user to review and modify the pre-selected destinations if needed, thus maintaining flexibility.

Inventive Principle:
Principle #10Preliminary action

AI summary

An information processing apparatus, which transmits a message to an information-sharing service managing messages on a thread format including a plurality of messages, obtains, in a case where a reply mode is set on the information processing apparatus by a user before a first message is transmitted to the information-sharing service with a scanned document, information on a plurality of threads from the information-sharing service, and extracts first threads relevant to the user from the obtained information on the plurality of threads. The extracted first threads are displayed, and the user specifies a thread from the displayed first threads as a first destination to which the first message is to be transmitted.
