Building semantic trees from XML documents

Building semantic trees from XML documents

The distributed nature of the Web, as a decentralized system exchanging information between heterogeneous sources, has underlined the need to manage interoperability, i.e., the ability to automatically interpret information in Web documents exchanged between different sources, necessary for efficient information management and search applications. In this context, XML was introduced as a data r...

Fuzzy Semantic Annotation of XML Documents

The e.dot project consists in the semi-automatic construction of an XML data warehouse in the field of food safety. The construction and the querying of the data warehouse are guided by an ontology. We are working on the annotation of tables extracted from scientific articles in microbiology with terms of the ontology. Terms from those articles may be connected to several terms of the ontology,...

Building the Semantic Web on XML

The semantic discontinuity between World-Wide Web languages, e.g., XML, XML Schema, and XPath, and Semantic Web languages, e.g., RDF, RDFS, and DAML+OIL, forms a serious barrier for the stated goals of the Semantic Web. This discontinuity results from a difference in modeling foundations between XML and logics. We propose to eliminate that discontinuity by creating a common semantic foundation ...

Generating Relations from XML Documents

This paper discusses several mechanisms for creating relations out of XML documents. A relation generator consists of two parts: (1) a tuple of path expressions and (2) an index indicating which path expressions may not be assigned the null value. Evaluating a relation generator involves finding tuples of nodes that satisfy the path expressions and are related to one another in a meaningful fas...
