Query answering has been addressed as a key issue in distributed environments such as Peer Data Management Systems (PDMS). An important step in this process regards query routing, i.e., how to find peers that are most likely to provide matching results according to the semantics of a submitted query. To help matters, we argue that semantic information(More)

An important step in this process regards query routing, i.e., how to find peers (data sources) that are most likely to provide results according to the submitted query.

Dynamic environments are descentralized systems that provide users with querying capabilities over a set of heterogeneous, distributed and autonomous data sources. Data Integration Systems, Peer Data Management Systems (PDMS) and Dataspaces are examples of such systems. They are composed by data sources (peers) that belong to a specific domain and are(More)
