Adaptive Search Result Presentation for Language Proficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foreign residents with limited language ability face difficulties in selecting target documents from search results due to the complexity of Japanese text, as existing technologies do not adequately assist in presenting search results in a format suitable for their language proficiency.
Innovation Solution
A document search result presentation apparatus that acquires information on the user's language ability and presents search results in a format corresponding to their proficiency, converting Kanji characters to hiragana or Roman characters, and providing assistance by displaying terms in a format higher than the user's language ability based on their work experience and language test grades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If document search results are presented in standard Japanese text format, then information completeness is maintained, but usability deteriorates for users with limited language ability
Solution Approach 1:
The patent segments the presentation of search results by dividing content into different language ability levels. It provides multiple presentation formats (e.g., simplified Japanese, English translations, annotated versions) for different user groups, allowing each user to access information appropriate to their language proficiency while maintaining access to the full original information if needed.
Solution Approach 2:
The patent applies local quality by providing differentiated information presentation tailored to specific user needs. Users with limited Japanese ability receive simplified or translated versions of specific portions of search results, while maintaining the option to access the original complete information. This allows localized adaptation of content difficulty without removing underlying information.
2Ease of operation
If search results are simplified for users with low language ability, then ease of operation improves, but measurement precision deteriorates in assessing user understanding
Solution Approach 1:
The patent implements dynamic adjustment of search result presentation based on detected user language ability. The system initially presents simplified versions to users with limited Japanese ability, then dynamically assesses their actual understanding level through interaction patterns, and progressively adjusts the complexity of presented information to match their demonstrated comprehension level.
Solution Approach 2:
The patent incorporates feedback mechanisms that monitor user interactions with search results (such as selection patterns, reading time, and correction requests) to continuously assess and refine the understanding of user language ability. This feedback loop allows the system to progressively improve its assessment precision while maintaining ease of operation through adaptive simplification.

AI summary
A document search result presentation apparatus includes a language ability information acquisition unit, a search term input unit, and a document search result presentation unit. The language ability information acquisition unit is configured to acquire information indicating a language ability of a searcher. The search term input unit is configured to receive a search term. The document search result presentation unit is configured to present document search results acquired as a result of execution of a process of searching for a document that includes the search term received by the search term input unit, in a presentation format corresponding to the language ability of the searcher, which is indicated by the information acquired by the language ability information acquisition unit.
