Splitting and Merging RDF Information Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack efficient mechanisms for splitting and merging information spaces while preserving semantic agreements and history, leading to volatility in 'split-merge' operations, which can result in information loss and inconsistencies.
Innovation Solution
A method that retrieves an information space represented by a Resource Description Framework (RDF) graph, splits it into sub-graphs, identifies and grounds broken links, creates rules for each new space, defines boundaries, and updates memory histories, allowing for efficient querying and subscription management across multiple agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If information space is split into multiple sub-spaces, then security and manageability are improved, but information loss and inconsistency occur due to broken links
Solution Approach 1:
The patent introduces a grounding mechanism that acts as an intermediary between split information spaces. When information spaces are divided, broken links are identified and grounded to external references or canonical forms, preserving the semantic relationships that would otherwise be lost. This mediator approach maintains information consistency across distributed spaces without requiring all spaces to maintain direct connections.
Solution Approach 2:
The patent performs preliminary identification of broken links before finalizing the split operation. By detecting and grounding broken links in advance, the system prevents information loss from occurring during the split process. This preliminary action ensures that semantic relationships are preserved before the information space is fully divided into separate entities.
2Adaptability or versatility
If semantic web standards are used for flexible multi-sourcing, then adaptability is improved, but complexity of managing information spaces increases
Solution Approach 1:
The patent segments information spaces into modular sub-spaces that can be independently managed while maintaining semantic coherence through grounding. Each sub-space can source information from different providers using Semantic Web standards, but the grounding mechanism ensures that overall consistency is maintained. This segmentation reduces management complexity by allowing localized handling of each sub-space while preserving global adaptability.
3Stability of the object's composition
If information spaces are merged after splitting, then original space is restored, but volatility occurs as merging may not produce initial space
Solution Approach 1:
The patent implements a boundary history memory that provides feedback about the state and boundaries of information spaces through split and merge operations. This history tracking allows the system to monitor changes and ensure that merge operations restore spaces correctly by comparing against the recorded boundary history. The feedback mechanism detects inconsistencies and prevents unreliable merges that would not restore the original space composition.

AI summary
An approach is provided for managing split operation for information spaces with respect to their information content. An information space that is represented by a graph is retrieved (131); a request to split the information space into a first new information space and a second new information space is received (133); one or more broken links of the graph is determined (135); one or more nodes of the graph that are to be grounded is identified (137); the graph is grounded based on the identified nodes (139); a first set of rules for the first new information space and a second set of rules for the second new rules for the information space are created (141); a first boundary for the first new information space and a second boundary for the second new information space along the broken links are defined (143); and history of the first new information space and history of the second new information space are updated based on the respective boundaries (145). A respective approach for managing merge operation for information spaces is also provided.
