Sentence Clustering Interface for FAQ Classification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for clustering sentences, such as those used in FAQ creation, often fail to accurately group sentences by intention, leading to inefficiencies in classification and retrieval, particularly in call centers where manual summarization is time-consuming and prone to errors.
Innovation Solution
An information processing apparatus and method that presents sentences within a cluster of interest and allows selection from these sentences, facilitating the creation of groups with shared intention by displaying sentences in a sentence selection region, ordered by proximity to the cluster center, and enabling efficient classification into existing FAQs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated clustering processing is used to group sentences, then productivity is improved, but manufacturing precision deteriorates because sentences cannot be accurately grouped by intention
Solution Approach 1:
The system segments the sentence classification process into two distinct phases: (1) automated clustering to generate initial groups based on similarity, and (2) manual confirmation where operators review and adjust the clustering results. This segmentation allows the system to leverage automated processing for efficiency while preserving human judgment for accuracy, directly resolving the contradiction between productivity and precision in sentence grouping.
Solution Approach 2:
The system implements a feedback mechanism where the results of automated clustering are presented to operators for review, and operator corrections are fed back to refine the clustering algorithm. This closed-loop feedback process enables continuous improvement of clustering accuracy while maintaining high productivity, as the system learns from human expertise without requiring manual classification of every sentence.
2Manufacturing precision
If manual summarization is used to create sentence groups, then manufacturing precision is improved, but productivity deteriorates due to time-consuming operations
Solution Approach 1:
The system performs preliminary automated clustering to generate draft sentence groups before manual review. This preliminary action reduces the workload on operators by pre-organizing sentences into logical groups, allowing them to focus only on confirming or adjusting the clustering rather than creating groups from scratch. This significantly improves productivity while maintaining the accuracy benefits of manual oversight.
Solution Approach 2:
The automated clustering algorithm performs self-service by automatically generating sentence groups based on similarity metrics, reducing the need for manual intervention. The system serves itself by identifying patterns and grouping sentences without human input, then presents these self-generated groups for operator confirmation, thereby improving productivity while preserving accuracy through selective human review.
3Manufacturing precision
If comprehensive sentence presentation is provided for selection, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The system applies local quality by presenting different information to different operators based on their specific needs and the characteristics of the sentences being classified. The interface adapts its complexity locally, showing detailed sentence options when precision is critical but simplifying the view when speed is more important. This localized adaptation maintains selection accuracy while preventing overall interface complexity from becoming unwieldy.
Solution Approach 2:
The sentence presentation interface is dynamic, allowing operators to adjust the level of detail and filtering options based on their current task requirements. The system can dynamically switch between presenting all sentences for comprehensive review or showing only borderline cases requiring human judgment. This dynamic adaptability maintains selection accuracy while managing interface complexity through on-demand information disclosure.

AI summary
Provided are an information processing apparatus and an information processing method capable of supporting work of giving a classification to a group of sentences. The information processing apparatus includes a presentation unit that presents a sentence included in a cluster of interest among clusters generated by clustering a sentence set in a sentence selection region, and a reception unit that receives selection of the sentence constituting a group of sentences from the sentences presented in the sentence selection region.
