User-Specific Worldview Construction for Personalized Information Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in finding relevant information from vast sources due to the lack of personalized approaches, as domain-specific ontologies may not accurately represent an individual's personal worldview, leading to inefficient information retrieval.
Innovation Solution
A method and system that capture and apply a user's reading style to construct their worldview, using a reading style engine that acquires and applies reading style, reading plan, and private ontology to identify and present information of interest, allowing for customizable report formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If domain-specific ontologies are used for information retrieval, then the system can leverage structured domain knowledge, but the ontology may not accurately represent the user's personal worldview leading to irrelevant results
Solution Approach 1:
The patent segments the monolithic domain ontology into a hierarchical structure with a general domain ontology and multiple user-specific private ontologies. Each user's private ontology captures their personal worldview, reading style, and preferences, allowing the system to maintain structured domain knowledge while adapting to individual user needs through selective combination of ontology layers.
Solution Approach 2:
The system dynamically adapts the ontology structure based on user interactions. The private ontology evolves as the system captures the user's reading style and worldview over time, transforming static domain knowledge into a dynamic, personalized information retrieval framework that adjusts to each user's unique perspective.
2Loss of information
If vast information sources are searched to find relevant information, then comprehensive coverage is achieved, but the time and effort required for information discovery increases significantly
Solution Approach 1:
The system performs preliminary action by pre-processing and structuring information according to the user's private ontology before actual information retrieval occurs. The reading style capture and worldview construction happen in advance, creating a personalized filter framework that rapidly processes vast information sources without requiring exhaustive manual search.
Solution Approach 2:
The private ontology acts as an intermediary layer between the user and vast information sources. It translates user needs into structured queries and filters information based on the user's personal worldview, efficiently bridging the gap between comprehensive information availability and personalized relevance without requiring the user to manually explore all sources.
3Ease of operation
If a generic information retrieval system is used, then ease of operation is maintained, but the system cannot present information tailored to the user's specific interests and worldview
Solution Approach 1:
The system implements self-service by automatically capturing the user's reading style and constructing their private ontology without requiring manual configuration. The worldview acquisition process occurs transparently through analysis of user interactions, maintaining ease of operation while progressively enhancing personalization as the system learns the user's preferences and information needs.
Data Source
AI summary
Disclosed herein is a method of capturing the reading style, reading plan and private ontology of a user, collectively referred to as the worldview. The process of capturing and applying the reading style includes the following activities: determining the reading style of the user, creating a worldview of the user using the reading style, applying the worldview to a document corpus, determining the information of interest, and reporting the desired information to the user in a report format. The worldview of the user is constructed out of the reading style and the reading plan of the user. Optionally, the user can choose to use a predetermined external ontology to create his/her worldview.
