Abstract

To explore the relationships between entities in RDF graphs, property path queries were introduced in SPARQL 1.1. However, existing RDF engines return only reachability of the entities ignoring the intermediate nodes in the path. If the paths are output, they are too many, which makes it difficult for users to find the most relevant paths. To address this issue, we propose a generalized top-k ranking technique that balances the trade-off between relevance and diversity. We propose a shortest path based relevance scoring in combination with several path similarity measures for diversification. With preliminary experiments and examples, we show that our diversification strategies provide more novel paths as our technique prioritizes diversity over path length.
