Abstract: | The problem of handling both the integration and the cooperation of a large number of information sources characterised by
heterogeneous representation formats is a challenging issue. In this context, a central role can be played by the knowledge
about the semantic relationships holding between concepts belonging to different information sources (intersource properties).
In this paper, we propose a semiautomatic approach for extracting two kinds of intersource properties, namely synonymies and
homonymies, from heterogeneous information sources. In order to carry out the extraction task, we introduce both a conceptual
model, for representing involved sources, and a metrics, for measuring the strength of the semantic relationships holding
among concepts represented within the same source. |
