Traditionally, machine translation is applied after publishing and does not have access to the original structure of the document, but only to its html representation.
The view-based transformation is achieved in two steps: an extension of the source base followed by a projection of the extended base.(Eighth.) 1860 - Atti dell.By Oughtred,"d.Nature.TaxoMap2 is a new implementation of taxoMap that reduces significantly runtime and enables parametrization by specifying the ontology language and different thresholds used to extract different mapping relations.Besides practical reasons, this is the case when decisions regarding access depend on factors which overpass the scope and knowledge of some of the entities involved.The proposed approach relies on OWL1, a W3C standard and swrl2, a W3C proposal.We also present an implementation that is compliant with XML and Web services standards, and is used as part of the axml nally, we experimentally measure the performance gains obtained by a careful filtering of the service calls to be triggered.First, we focus on a very wide class of query plans that capture the spirit of many techniques usually considered in existing systems.The fixpoint query computes an equivalence relation on tuples which is a congruence with respect to the rest of the computation.Databases and Finite Model Theory Victor Vianu- 1997 Databases provide one of the main concrete scenarios for finitemodel theory within computer science.337 (London) 1904 - American Machinist.Our main contribution is to characterize various complexity classes between Ptime and Pspace, by several logical means, thus translating open questions in complexity theory to open questions in logic related to the use of the non-determinism.(Paris) 1878 - Spiral Slide Rule.We give models whose definable sets are all star-free, butwhose binary relations are quite complex, as well as models whose definable sets include all regular sets, but whichare much more restricted and tractable than the full algebraof regular relations.The ActiveView system combined with the Axielle XML repository enables a fast deployment of electronic commerce applications based on a new high-level declarative specification language (AVL advanced database technology (object-oriented data model, XML query language, notifications Web standards (http, html) and other Internet compliant technologies.The Green method is found to have both the best average results and the best robustness.0 10. .The promotion billet disneyland paris collaborating peers that form the Data Ring are autonomous, heterogeneous and their capabilities may greatly vary,.g., from a sensor to a large database.New emerging paradigms, like the Semantic Web, use ontologies for describing metadata and are defined, in part to aid in Web evolution.The operations are implemented very efficiently by the database engine, and the equivalences are used to optimise the query.The problem is infeasible in general and we present a number of negative results.
Apport d'une ontologie du domaine pour affiner une requ Brigitte Safar, Hassen Kefi- ieee Transactions on Knowledge and Data Engineering 2003 In this paper we study how to help used to refine his query when the search for documents in ressources has produced too many.
Since time in the polynomially-bounded machine coincides with time in the uniform circuit model, this also shows that reflection allows for more "intense" parallelism, not attainable otherwise.
Moreover, their expressive power can be characterized over unordered finite structures in terms of the complexity class NP " co-NP.
In this paper, we present some preliminary results, together with promising directions of research to address this fundamen tal issue.
