Abstract
This electronic catalog searching system first, calculates attribute relevance (e.g., strongly-relevant, weakly-relevant, and irrelevant) for each node in a hierarchy (e.g., abstraction hierarchy, decompositional hierarchy) based on assignment constraints made at the nodes representing real-world concrete entities and then combines attribute relevance with a forward-checking parametric search to implement a hierarchical exploration scheme that can be enabled over a multitude of hierarchies residing on a base of concrete entities.
