Reputation Analysis via Voluntary Action Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to continuously and constantly measure changes in reputation over time for a subject, as expressions used by writers are not consistently exhibited, making it difficult to accurately determine if a reputation change has occurred.
Innovation Solution
A reputation analysis system that extracts descriptions of voluntary actions related to a subject and counts their appearances over time to estimate reputation time-series data, distinguishing between voluntary and involuntary actions to provide continuous and constant evaluation insights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If evaluation expressions are extracted from documents to measure reputation, then reputation analysis can be performed, but the expressions are not continuously exhibited making accurate measurement difficult
Solution Approach 1:
The patent changes the parameter being measured from explicit evaluation expressions (adjectives, adjectival verbs) to voluntary action expressions (verbs indicating voluntary actions). This parameter change allows continuous measurement because voluntary actions are exhibited more consistently in documents than evaluation expressions, while still enabling reputation analysis through the relationship between voluntary actions and subject matters.
2Loss of information
If explicit evaluation expressions are used to analyze reputation, then reputation can be extracted, but the expressions do not continue being exhibited continuously and constantly
Solution Approach 1:
The patent introduces voluntary action expressions as an intermediary to connect document content with reputation measurement. Instead of directly using evaluation expressions that are sporadically exhibited, the system uses voluntary actions (which are exhibited continuously) as a mediator to infer reputation, thereby maintaining continuous measurement capability while preserving information completeness.
3Productivity
If all actions are treated equally in reputation analysis, then simple counting can be performed, but voluntary and involuntary actions cannot be distinguished reducing accuracy
Solution Approach 1:
The patent segments actions into two categories: voluntary actions and involuntary actions. By dividing the set of all actions into these distinct segments, the system can selectively count only voluntary actions when measuring reputation, thereby maintaining analysis efficiency through automated classification while improving measurement precision by excluding irrelevant involuntary actions.

AI summary
Described are a reputation analysis device, reputation analysis method, and reputation analysis-use program capable of suitably analyzing temporal changes in reputation for an object indicated by a keyword. The disclosed reputation analysis device is provided with a voluntary activity description extraction means for extracting descriptions representing voluntary activity related to an object indicated by a keyword that has been input from within a plurality of documents; and a reputation chronological data estimation means for counting the number of occurrences of voluntary activity at each time point wherein the voluntary activity expressed by a description representing the voluntary activity related to the object has been performed, and estimating reputation chronological data for chronologically representing evaluations for the object by the agents of the voluntary activity.
