Approximate Query Answering for a Heterogeneous XML Document Base
In this paper, we deal with the problem of effective search and query answering in heterogeneous web document bases containing documents in XML format of which the schemas are available. We propose a new solution for the structural approximation of the submitted queries which, in a preliminary schema matching process, is able to automatically identify the similarities between the involved schem...
متن کاملAn Improved Semantic Schema Matching Approach
Schema matching is a critical step in many applications, such as data warehouse loading, Online Analytical Process (OLAP), Data mining, semantic web [2] and schema integration. This task is defined for finding the semantic correspondences between elements of two schemas. Recently, schema matching has found considerable interest in both research and practice. In this paper, we present a new impr...

Objectives of the WP. The key objectives were: 1. Develop new techniques and algorithms for schema mapping and Web data exchange; and 2. Develop new techniques and algorithms for improving query evaluation by making use of schema information. The first objective is represented by tasks T2.1 (Schema Mappings for XML) and T2.2 (Data Exchange for XML Documents), and the second by tasks T2.3 (Query...
متن کاملTranslating WFS Query to SQL/XML Query
The purpose of the WFS specification, proposed by the the OpenGIS Consortium (OGC), is to describe the manipulation operations over geospatial data using GML. Web servers providing WFS service are called WFS Servers. WFS servers publish GML views of geographic features stored in data sources such that the user can query and update data sources through a user defined feature type schema. In this...
متن کاملExploiting related digital library corpora with query rewriting
In this paper, we present the preliminary results of the ongoing research activity we are carrying out in the context of approximate XML query answering when the schemas of the XML documents are available. The method we propose involves a preliminary schema matching process, which automatically identifies the semantic and structural similarities between the schema elements to be used in the sub...
