VR-Tree: A novel tree-based approach for modeling Web Query Interfaces

摘要: Web Query Interfaces (WQIs) play a very important role in retrieving Deep content. WQIs allow users to query domain-specific databases for obtaining information of interest from diverse domains such as car rentals, hotels, airfare, etc. As the number on web is increasing drastically, some research efforts are focused building single (unified) WQI that allows and integrate available different related specific domain. A task this WQIs’ integration process extraction, modeling understanding semantic However, challenging because great heterogeneity design WQIs. This paper presents novel tree-based approach tree schema called Visual Reduced Tree (VR-Tree) built produced by browser’s render engine, applying set well- defined functions guided heuristic rules identify WQI’s main components their relationships. The proposed strategy was evaluated running collection experiments over Tel-8 ICQ datasets UIUC repository. results show automatic possible with high degree precision if compared against previous approaches, simplifying only considering visual spatial properties using VR-Tree work.
