DESCRIPTION:Ontologies and ontology based systems are becoming increasingl
 y\nimportant in meeting the demand for more powerful and flexible\ninforma
 tion systems. Requirements for such systems include the need to\ndeal with
  incomplete and semi-structured information\, to integrate\ninformation fr
 om heterogeneous sources\, to employ richer and more\nflexible schemas\, a
 nd for query answers to reflect both knowledge and\ndata. Provision of suc
 h enhanced capabilities must\, however\, be in\naddition to\, and not inst
 ead of\, the well-established features of\nexisting database systems\, in 
 particular their robust\nscalability. Achieving this is\, of course\, extr
 emely challenging. In\nthis talk I will present some recent research effor
 ts that tackle this\nproblem\, including investigations of tractable fragm
 ents\, new\nalgorithmic techniques\, new optimisations and the exploitatio
 n of\nrelational database technology.\n
