Operation Pattern Extraction Using State-Order Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques struggle to express operation patterns uniformly using both state and order, making it difficult to determine if an operation is performed in a certain order while a specific state is satisfied.
Innovation Solution
An extraction device that processes circuitry to create operation patterns using a state of an operation result and its order, encoding states as binary values and using regular expressions to uniformly express both state and order, enabling efficient matching of operation logs both offline and online.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate techniques are used to express state and order independently, then each can be expressed individually, but it becomes impossible to express operation patterns that require both state and order simultaneously
Solution Approach 1:
The patent merges the separate state expression technique and order expression technique into a unified operation pattern expression system. The state information (URL, title, UI presence) and order information (chronological sequence) are combined into a single operation pattern structure that can be matched against operation logs simultaneously, resolving the contradiction between versatility and complexity.
Solution Approach 2:
The operation pattern structure serves multiple functions: it captures state information (what was displayed), order information (when operations occurred), and enables pattern matching (whether operations matched expected sequences). This multi-functional design allows a single system to handle both state and order expression uniformly.
2Measurement precision
If detailed state information is captured for each operation, then operation status can be precisely determined, but processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-defining operation patterns with expected state information (URL, title, UI elements) and chronological orders before actual operation logging. During runtime, the system only needs to check whether actual operations match these pre-defined patterns, significantly reducing processing time while maintaining precise operation status determination.
