Context-Aware Ambiguous Term Resolution in Handwritten and Audio Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in efficiently converting unstructured handwritten and audio notes into structured data, as existing methods face difficulties with ambiguity in recognition, such as 'dock' and 'clock' being indistinguishable in handwriting and 'seventy' and 'seventeen' in voice notes, leading to productivity inefficiencies in data entry for systems like CRM and project management.
Innovation Solution
A computer-implemented method that analyzes structured data templates to build lexical and phonetic spaces, maps multi-variant answers from handwriting and voice recognition, and uses contextual information to select the correct terms, employing structural attachment tokens and hints to resolve ambiguities through cross-validation and user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic recognition (conversion to text, transcription) of handwritten and voice data is performed, then data conversion speed is improved, but recognition accuracy deteriorates due to ambiguous terms
Solution Approach 1:
The patent segments the data conversion process into multiple stages: initial automatic recognition to generate candidate terms, contextual analysis to filter and select from candidates, and validation mechanisms. This segmentation allows the system to maintain high conversion speed while improving accuracy through multi-stage processing that addresses ambiguous terms systematically.
Solution Approach 2:
The patent introduces contextual information as an intermediary element between the raw recognized text and the final structured data. This intermediary layer analyzes the context surrounding ambiguous terms, compares them against templates, and mediates the selection process, thereby resolving ambiguities without sacrificing conversion speed.
2Measurement precision
If manual conversion of unstructured information into structured data is performed, then data accuracy is improved, but time consumption increases
Solution Approach 1:
The patent performs preliminary automatic recognition and template matching to pre-process unstructured data before manual intervention. This preliminary action handles the bulk of the conversion work, generating structured data outputs that require minimal manual verification, thus maintaining high accuracy while significantly reducing time consumption compared to fully manual conversion.
Solution Approach 2:
The system enables self-service by automatically performing the majority of the conversion task from unstructured to structured data. The automated recognition, contextual analysis, and template matching processes handle the conversion independently, with only minor manual corrections needed, thereby reducing the time investment required from users.
3Adaptability or versatility
If multi-variant answers from handwriting and voice recognition are generated, then coverage of possible interpretations is improved, but complexity of data processing increases
Solution Approach 1:
The patent applies local quality by analyzing and processing only the specific contextual regions surrounding ambiguous terms rather than the entire dataset. The contextual analysis focuses locally on the immediate surroundings of problematic terms, comparing them against relevant templates and selecting the most appropriate interpretation, thereby managing complexity while maintaining comprehensive coverage.
Solution Approach 2:
The system generates multiple candidate terms (excessive action) to ensure comprehensive coverage of possible interpretations, then applies selective filtering based on contextual analysis. This partial action approach ensures that all plausible interpretations are initially considered, while the subsequent selection process manages complexity by not processing all possibilities equally, but rather focusing on the most likely candidates.
Data Source
AI summary
This application is directed to recognizing unstructured information based on hints provided by structured information. A computer system obtains unstructured information collected from a handwritten or audio source, and identifies one or more terms from the unstructured information. The one or more terms includes a first term that is ambiguous. The computer system performs a recognition operation on the first term to derive a first plurality of candidate terms for the first term, and obtains first contextual information from an information template associated with the unstructured information. In accordance with the first contextual information, the computer system selects a first answer term from the first plurality of candidate terms, such that the first term is recognized as the first answer term.
