In a Peer Data Management System (PDMS), semantic peers connect with each other through semantic mappings between their own schemas. Because of schema heterogeneity, due to peers' autonomy as for data representation, querying a PDMS implies query reformulations across semantic mappings, possibly incurring in a semantic degradation due to the reiterated approximations given by the traversal of long paths.

Abstract

In a Peer Data Management System (PDMS), semantic peers connect with each other through semantic mappings between their own schemas. Because of schema heterogeneity, due to peers' autonomy as for data representation, querying a PDMS implies query reformulations across semantic mappings, possibly incurring in a semantic degradation due to the reiterated approximations given by the traversal of long paths. The linkage closeness of semantically similar peers is thus a crucial issue. In this paper we present a strategy for the incremental maintenance of a flexible network organization for PDMSs that clusters together semantically related peers.
