Linked data: un’opportunità per il riuso

The usage of the sources available on the web constitutes an enormous opportunity in the conversion processes of bibliographic catalogs in linked open data: the entity resolution processes, to identify objects in the real world, and the data enrichment mechanisms, to enhance the end user’s search experience, makes it essential to use other sources other than their own data. But not everything available on the web is really usable: factors related to data quality and interoperability can complicate or even prevent the reciprocal exchange of information data. This analysis presents some cases of usage of external sources for the processes mentioned above, highlighting the critical elements that are more easily encountered in the phases of data reuse and the possible hypotheses of solution.
