Personalized Information Access in a Bibliographic Peer-to-Peer System

An Interest-based P2P RDF Query Architecture

“…First, we just use paper classification to describe peer interest, but [8] have pointed out that the query history is also an important factor to peer interest, so we should take further study on how to describe peer interest more exactly. Secondly, for building distributed interest-index, we register all parent topics of every topic, which produce too many redundancies.…”

A flexible semantic inference methodology to reason about user preferences in knowledge-based recommender systems

“…Another recommender system that relies on ontologies is Bibster, a semantics based peer-to-peer (P2P) system aimed at researchers that share bibliographic metadata [16]. The goal is to provide the users with personalized access to the metadata available in the P2P network.…”

“…1) that represent some TV programs and properties between them and their semantic attributes. 16 On the other one, we suppose that AVATAR elaborates a personalized recommendation for the user U, whose preferences are the reduced subset of programs and attributes shown in Fig. 2.…”

“…For this purpose, the authors use an ontology for representing the knowledge of the application domain. As recommendation strategy, [16] proposes a semantic similarity metric in order to compare the user's expertise (inferred from the bibliographic metadata stored in his/her local repository) to the data that other users want to share. This comparison process is based on the hierarchical relationships stated in the ontology and some properties explicitly represented in it.…”
