We investigate a class of path constraints that is of interest in connection with both semistructured and structured data. In standard database systems, constraints are typically ...
Regular path queries are the basic navigational component of virtually all the mechanisms for querying semistructured data commonly found in information integration applications, W...
In a semi-structured database there is no clear separation between the data and the schema, and the degree to which it is structured depends on the application. Semi-structured da...
In this paper we describe the development of an ontology of molecular and phenotypic cereals data, realized by integrating existing public web databases with the database developed...
In [3], we introduced a framework for querying and updating probabilistic information over unordered labeled trees, the probabilistic tree model. The data model is based on trees ...
