There has been an explosion in the types, availability and volume
of data accessible in an information system, thanks to the World
Wide Web (the Web) and related inter-networking technologies. In
this environment, there is a critical need to replace or complement
earlier database integration approaches and current browsing and
keyword-based techniques with concept-based approaches. Ontologies
are increasingly becoming accepted as an important part of any concept
or semantics based solution, and there is increasing realization
that any viable solution will need to support multiple ontologies
that may be independently developed and managed. In particular, we
consider the use of concepts from pre-existing real world domain
ontologies for describing the content of the underlying data repositories.
The most challenging issue in this approach is that of vocabulary
sharing, which involves dealing with the use of different terms or
concepts to describe similar information. In this paper, we describe
the architecture, design and implementation of the OBSERVER system.
Brokering across the domain ontologies is enabled by representing
and utilizing interontology relationships such as (but not limited
to) synonyms, hyponyms and hypernyms across terms in different ontologies.
User queries are rewritten by using these relationships to obtain
translations across ontologies. Well established metrics like precision
and recall based on the extensions underlying the concepts are used
to estimate the loss of information, if any.
