WebQuIn-LD: a method of integrating web query interfaces based on linked data

摘要: The deep web is a huge source of domain-specific information (sale of houses, medical information, e-commerce, science, etc) stored in database servers accessible through HTML forms called web query interfaces (WQIs). Information in the deep web is retrieved by querying one database server at a time, which results inefficient. A more attractive approach is to create an integrated WQI (IWQI) that acts as single entry point to query several database servers at a time for a given domain. Schema matching and string (labels in WQIs) comparison have been the most popular techniques to create IWQIs. In this work, we propose a new method for the integration of web forms based on linked data and the VDIS (View-based Data Integration System) architecture. We present WebQuIn-LD, an alternative and novel approach relying on linked data principles to combine individual WQIs into a single IWQI for a given domain is …
