XBRL Mapping Device Matching Rates for Data Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mapping devices face difficulties in optimally associating XBRL data items before and after changes, particularly when item names, auxiliary information, and display orders are modified, leading to challenges in accurately mapping parent-child and sibling relationships.
Innovation Solution
A computer-readable recording medium storing a mapping program that calculates matching rates between top-level parent items in XBRL data before and after changes based on item information, including item names, label names, reference names, and child item counts, to associate parent items and child items effectively.

Engineering Contradiction Analysis
1Measurement precision
If the mapping device focuses on comparing parent-child relationships, sibling relationships, or auxiliary information between items before and after change, then it can identify some mappings, but it fails to optimally associate items when multiple pieces of information (item names, auxiliary information, display orders) are changed simultaneously
Solution Approach 1:
The patent segments the mapping process into distinct phases: first comparing top-level parent items using multiple criteria (item names, label names, reference names, number of child items) to calculate matching rates, then separately comparing child items based on their parent item mappings. This segmentation allows the system to handle multiple information changes systematically by breaking down the complex mapping problem into manageable comparison steps, thereby improving mapping accuracy even when multiple pieces of information change simultaneously.
2Device complexity
If the mapping device compares only item names and simple auxiliary information, then the comparison process is simple, but it cannot reliably determine mappings when label names, reference names, or display orders are also changed
Solution Approach 1:
The patent merges multiple comparison criteria (item names, label names, reference names, and number of child items) into a unified matching rate calculation for top-level parent items. By combining these diverse comparison dimensions, the system creates a more robust mapping determination that remains reliable even when some individual criteria change. The merged comparison approach ensures that mapping reliability is maintained by considering multiple aspects simultaneously rather than relying on a single comparison metric.
3Reliability
If the mapping device uses comprehensive comparison criteria including label names and reference names, then mapping reliability improves, but the calculation and comparison process becomes more complex
Solution Approach 1:
The patent performs preliminary comparison actions by first calculating matching rates for top-level parent items using comprehensive criteria (item names, label names, reference names, number of child items) before proceeding to compare child items. This preliminary action establishes a solid foundation for subsequent comparisons, ensuring that the mapping process maintains high reliability from the outset. By completing the top-level parent item comparisons first, the system creates a structured framework that guides the remaining mapping operations, thereby managing complexity through systematic sequencing.

AI summary
A non-transitory computer-readable recording medium has stored therein a mapping program that causes a computer to execute a process. The process includes: first calculating a matching rate between top-level parent items in a hierarchical relationship between a first plurality of items of a first data and a second plurality of items of a second data based on an item information relating to the first plurality of items and the second plurality of items, the first data including one or a plurality of items before a change, the second data including one or a plurality of items after the change; and associating the parent items of the first data and the second data with each other based on the calculated matching rate.
