Electronic Device Character Set Identification via Sentence Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when selecting characters on a display to search for their meaning or related information, as they struggle to accurately adjust the start and end points of the characters to be searched.
Innovation Solution
An electronic apparatus that includes a processor and memory, enabling it to analyze sentences based on user input, select character sets, and display them distinctively, using connectivity scores, generality scores, and grammatical structures to identify and highlight relevant character sets, including those not adjacent to each other, and utilizing search history for improved accuracy.

Engineering Contradiction Analysis
1Measurement precision
If a user manually selects characters on a display to search for meaning or related information, then the search function can be performed, but the user experiences inconvenience in accurately adjusting the start and end points of the characters
Solution Approach 1:
The system performs preliminary analysis of the sentence structure and character connectivity before the user completes their selection. By pre-calculating potential character sets and their relevance scores, the system prepares multiple candidate selections in advance, allowing the user to simply confirm rather than precisely adjust boundaries.
Solution Approach 2:
The system provides feedback by displaying multiple candidate character sets with different relevance scores as the user drags the selection. This real-time feedback allows the user to see potential matches and adjust their selection accordingly, or simply confirm the top candidate without precise manual adjustment.
2Measurement precision
If the system provides multiple character set candidates based on sentence analysis, then the accuracy of character set identification is improved, but the complexity of the selection process increases
Solution Approach 1:
The system applies different quality levels to different character set candidates by ranking them according to relevance scores. The top candidate receives the highest quality presentation (e.g., highlighted display), while other candidates are presented with decreasing emphasis. This allows the system to provide accurate multiple candidates without overwhelming the user with equal complexity.
3Measurement precision
If the system analyzes sentences using connectivity scores and grammatical structures, then the precision of character set selection is improved, but the processing time and computational resources increase
Solution Approach 1:
The system performs partial analysis by focusing only on the local sentence context surrounding the user's selection rather than analyzing the entire document. By limiting the analysis scope to a window around the selected characters and using heuristic rules for connectivity scoring, the system achieves good precision without excessive processing time.

AI summary
Provided is an electronic apparatus. A method of controlling the electronic apparatus includes displaying at least one sentence, when receiving a user input regarding at least one character of the at least one sentence that is displayed, analyzing the at least one sentence by using the at least one sentence including at least one character and the at least one character, selecting a character set included in the at least one sentence according to an analysis result, and displaying a selected character set to be distinguished from other characters included in the at least one sentence.
