Automated Study Material Construction via Expression Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing English teaching methods focus on problem-solving and memorization, limiting the accuracy of expression meaning conveyance for non-native speakers, as descriptions in dictionaries are theoretical and in a different language.
Innovation Solution
An apparatus and method that automatically constructs study materials by collecting documents from websites, separating script and description portions, extracting expression description sentences, and measuring similarity to provide accurate, language-matched descriptions for English expressions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If English expressions are described using traditional English dictionaries, then the descriptions are available, but the accuracy of meaning conveyance is limited because descriptions are theoretical and in a different language
Solution Approach 1:
The patent introduces a mediator system that automatically collects bilingual expressions and descriptions from multiple websites, processes them through classification and extraction algorithms, and presents them in a unified format. This intermediary processing layer transforms scattered web content into structured learning material that maintains accuracy while improving accessibility for learners
Solution Approach 2:
The system copies expressions and descriptions directly from authentic bilingual sources (websites, documents) rather than relying on traditional dictionary compilations. By copying real-world usage examples and maintaining the original language context, the system preserves accuracy while making the content more relevant and usable for learners
2Manufacturing precision
If study materials are manually created with accurate expressions and descriptions, then the quality is high, but the time and effort required is excessive
Solution Approach 1:
The system performs self-service by automatically collecting, classifying, extracting, and organizing expression data from multiple websites without requiring manual intervention. The automated classification algorithms and extraction processes enable the system to generate high-quality study materials independently, eliminating the time-consuming manual creation process while maintaining quality through systematic processing
Solution Approach 2:
The system performs preliminary actions by pre-collecting and pre-processing expression data from multiple sources before it is needed. The automated classification and extraction processes are executed in advance, creating a ready-to-use database of expressions and descriptions that can be quickly deployed for learning purposes without last-minute manual preparation
3Adaptability or versatility
If expressions are extracted from multiple websites, then the variety and accuracy of expressions improve, but the complexity of data processing increases
Solution Approach 1:
The patent segments the complex data processing task into distinct functional modules: a collection unit that gathers data from multiple websites, a classification unit that categorizes expressions by type and context, and an extraction unit that isolates specific expression patterns. This segmentation allows the system to handle diverse expression data from multiple sources while managing processing complexity through structured, modular operations
Data Source
AI summary
Disclosed is an apparatus and method for processing documents to extract expressions and descriptions. The apparatus for processing documents includes a document collection unit, which collects documents from websites and divides each of the collected documents into a script portion and a description portion to thus generate a script document and a description document, and an expression extraction unit, which extracts expression description sentences on the basis of the description document, and extracts expressions described by the expression description sentences from the script document. According to the invention, study material, including a pair that comprises an expression to be studied and a description thereof, can be automatically constructed.
