Semantic-based Query Routing for PDMS

Crishane FreireDamires SouzaAna Carolina Salgado

Query routing is a key issue in dynamic distributed environments such as Peer Data Management Systems (PDMS). The dynamicity of the environment and the amount of heterogeneous and autonomous data sources available in the system have made hard the task of finding relevant results to user queries. We argue that the semantic knowledge around this process is rather important to select the most relevant peers to send a query and produce results which best meet the users' needs. To achieve and deal with such knowledge, we combine two important aspects: semantic information and information quality. In this light, we present a semantic-based query routing approach for PDMS and highlight important issues related to this problem.
