Sentence Extraction System Context Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sentence extraction techniques fail to enhance accuracy by not considering context, leading to incorrect extraction of performance factor sentences in financial reports, where relevant sentences may be missed or noise is included.
Innovation Solution
A sentence extraction system that specifies candidate sentences based on extraction conditions, identifies linked sentences, and determines extraction based on the context, using scores and criteria to refine the extraction process, ensuring accurate identification of performance factor sentences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sentence extraction is performed based on keyword presence and modification relationship without context consideration, then extraction speed is maintained, but extraction accuracy deteriorates
Solution Approach 1:
The extraction process is divided into multiple stages: initial candidate sentence extraction based on keywords, context analysis stage, and final determination stage. This segmentation allows the system to apply simple keyword matching first, then add context analysis only where needed, improving accuracy without proportionally increasing complexity
Solution Approach 2:
The system performs preliminary extraction of candidate sentences using simple keyword matching before applying more complex context analysis. This preliminary action filters out obviously irrelevant sentences first, reducing the workload for subsequent context-based verification and improving overall efficiency
2Measurement precision
If context is not considered in sentence extraction, then processing speed is maintained, but relevant sentences are omitted and noise is included
Solution Approach 1:
The system applies context analysis selectively rather than to all sentences. It performs full context analysis on candidate sentences that meet initial keyword criteria, while skipping sentences that clearly don't match. This partial application of the more time-consuming context analysis method improves accuracy for relevant sentences without proportionally increasing processing time for the entire document

AI summary
At least one processor of a sentence extraction system specifies at least one candidate sentence based on a predetermined extraction condition, the candidate sentence being a candidate for a sentence to be extracted from among a plurality of sentences; specifies at least one linked sentence that has a link to the at least one candidate sentence; and determines whether to extract the at least one linked sentence, based on whether to extract the at least one candidate sentence.
