Supporting graceful schema evolution represents an unsolved problem for traditional information systems that is further exacerbated in web information systems, such as Wikipedia and public scientific databases: in these projects based on multiparty cooperation the frequency of database schema changes has increased while tolerance for downtimes has nearly disappeared. As of today, schema evoluti...

This paper has one main goal, which is a negative one. It aims at showing that the theory of NPI licensing defended in von Fintel (1999) is empirically inadequate. In essence, the theory we’re discussing relies on so-called Strawson-entailment, a device which ensures that weak NPIs are licensed despite the presence of presuppositions. We level two main criticisms against von Fintel’s theory. Fi...

This paper presents a branching schema for the solving of a wide range of interval constraint satisfaction problems defined on any domain of computation, finite or infinite, provided the domain forms a lattice. After a formal definition of the branching schema, useful and interesting properties, satisfied by all instances of the schema, are presented. Examples are then used to illustrate how a ...

nowadays, standardized metadata for geospatial data is a key in sharing and finding information on the web and crucial in building geospatial data infrastructure (gdi). the main objective of this paper was to develop a web-based metadata dissemination system for in-situ sensors based on, most importantly, interoperable, standard and open technologies introduced by open gis consortium (ogc), nam...

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...
