Context-Based Query Formulation for Information Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information retrieval systems fail to effectively address the challenges of information overload and semantic heterogeneity, as they cannot adequately customize information aggregation based on user workflows, tasks, and context, leading to inefficient and irrelevant query results.
Innovation Solution
A context-based query formulation and information retrieval system that models workflow activities, generates meta-queries using user profiles and ontologies, and aggregates information from multiple sources, utilizing worklet modeling and meta-query templates to provide relevant, mission-oriented knowledge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing information retrieval systems are used, then the system structure is simple, but information overload and irrelevant data increase
Solution Approach 1:
The system applies local quality by customizing information retrieval according to user-specific context including workflow, task, role, and preferences. Instead of providing uniform information, the system tailors query formulations and retrieval parameters to match individual user needs, thereby reducing information overload while maintaining system simplicity.
Solution Approach 2:
The system performs preliminary actions by modeling user workflows and tasks in advance, preparing context profiles before actual information retrieval occurs. This pre-modeling enables the system to automatically generate personalized queries and retrieve relevant information more efficiently, improving user efficiency without increasing operational complexity.
2Reliability
If information aggregation is customized based on user context, then information relevance improves, but system complexity increases
Solution Approach 1:
The system achieves universality by implementing a multi-functional framework that handles workflow modeling, task analysis, query formulation, and information aggregation through a unified context-based approach. This universal system can serve multiple users with different roles and preferences without requiring separate customized systems for each, thereby improving information relevance while managing system complexity through standardized processes.
Solution Approach 2:
The system introduces an intermediary layer of context modeling and query formulation that mediates between user needs and information sources. This intermediary layer translates diverse user contexts into standardized retrieval queries, improving information relevance while isolating the complexity of customization from the core retrieval mechanism.
3Productivity
If automated information aggregation is implemented, then productivity increases, but automation extent remains limited
Solution Approach 1:
The system implements self-service automation where the context modeling framework automatically analyzes user workflows, generates appropriate queries, and aggregates information without requiring manual intervention. The system serves itself by autonomously adapting to user needs and performing information retrieval tasks, thereby increasing productivity while achieving a high extent of automation through self-directed operation.
Data Source
AI summary
A method for context-based query formulation and information retrieval and aggregation is described. The method includes modeling one or more workflow activities utilized to perform work tasks, preparing at least one meta-querying template, to generate queries that utilize the modeled workflow activities, retrieving information relevant to the work task as determined utilizing the at least one meta-querying template, and aggregating the retrieved information for presentation to the user.
