Abstract: | Meta-searching library communities involve access to sources where metadata are invisible behind query interfaces. Many of the query interfaces utilize predefined abstract Access Points for the implementation of the search services, without any further access to the underlining meta-data and query methods. The unsupported Access Points and its consequences, either query failures or inconsistent answers, is the main issue when meta-searching this kind of systems. An example of the abstract Access Point based search model is the Z39. 50 information retrieval protocol, which has wide acceptance and use from the library community. In this paper we present the zSAPN (Z39. 50 Semantic Access Point Network), a system which improves the search consistency and lowers the query failures exploiting the semantic information of the Access Points from an RDFS description. The current implementation of zSAPN is in the context of the Z39. 50 protocol, using the official specification of the Access Point semantics and benefiting the huge number of the available sources worldwide. zSAPN substitutes each unsupported Access Point with a set of other supported ones, whose appropriate combination would either broaden or narrow the initial semantics, according to the user’s choice. |
