1Productivity
If existing graph database tools (Neo4j, TigerGraph) are used for large-scale heterogeneous graph processing, then basic graph storage and querying capabilities are provided, but computational speed is limited and scalability is restricted due to lack of linear algebra optimizations and lazy evaluation
Solution Approach 1:
The patent replaces traditional graph traversal mechanisms with linear algebra operations. Graph projections are formulated as matrix multiplication operations, enabling utilization of highly optimized BLAS (Basic Linear Algebra Subprograms) libraries and GPU acceleration, thereby achieving significant computational speedups while maintaining manageable system complexity through mathematical abstraction
Solution Approach 2:
The patent changes the computational parameters by introducing lazy evaluation strategies where graph projections are not immediately computed but represented as executable plans. This allows deferred computation until results are actually needed, improving computational efficiency by avoiding unnecessary calculations and enabling better resource utilization
2Ease of operation
If comprehensive graph analysis tools are provided, then analytical capabilities are enhanced, but visual feedback during transformations is lacking, reducing usability
Solution Approach 1:
The patent implements visual feedback mechanisms that display intermediate results and transformation progress during graph projection operations. This allows users to monitor the computation process, understand data flow, and make informed decisions about parameter adjustments, thereby enhancing usability without losing critical visual information
3Loss of time
If graph transformations are executed immediately, then results are obtained quickly for simple queries, but runtime increases significantly for complex large-scale transformations
Solution Approach 1:
The patent performs preliminary actions by pre-computing and caching intermediate results that can be reused across multiple projections. The system identifies common subexpressions in graph transformation pipelines and computes them once, storing results for later retrieval, thereby reducing overall runtime for complex transformations while improving computational efficiency through avoided redundant calculations
