摘要: Personal Information Management (PIM) systems aim to provide convenient access all data and metadata on a desktop the user itself as well co-workers. Obviously, sharing with co-workers raises privacy control issues which have be addressed. In this paper we discuss these issues, present appropriate solutions. line architecture of current PIM [8, 2, 11, 15], our solutions cover semantic shared in such context, i.e. resources other structures created by system, an RDF store inverted index entries for efficient textual search. We different kinds policies specify protection metadata, describe system express execute efficiently. Additionally, extension existing Beagle++, approach, experiments, convincing results performance scalability.
