Abstract:
In this paper, we present MELIS (Meaning Elicitation and Lexical Integration System), a method and a
software tool for enabling an incremental process of automatic annotation of local schemas (e.g. relational
database schemas, directory trees) with lexical information. The distinguishing and original feature of MELIS
is its incrementality: the higher the number of schemas which are processed, the more background/domain
knowledge is cumulated in the system (a portion of domain ontology is learned at every step), the better the
performance of the systems on annotating new schemas.
MELIS has been tested as component of MOMIS-Ontology Builder, a framework able to create a domain ontology
representing a set of selected data sources, described with a standard W3C language wherein concepts
and attributes are annotated according to the lexical reference database.
We describe the MELIS component within the MOMIS-Ontology Builder framework and provide some experimental
results of MEL
IS as a standalone tool and as a component integrated in MOMIS.
