2018 Text Retrieval Conference  
We describe our participation in the TREC 2018 Common Core track, where we experimented with hyperedge-based document ranking, over the hypergraph-of-entity.  ...  This resulted in six additional runs (3 to 8), using feup-run1 and feup-run2 as the base runs for reranking.  ...  ACKNOWLEDGMENTS José Devezas is supported by research grant PD/BD/128160/2016, provided by the Portuguese national funding agency for science, 5  ...

Hypergraph-of-Entity: A General Model for Entity-Oriented Search [article]

José Devezas, Sérgio Nunes
2021 arXiv   pre-print
This enables us to compare the effectiveness of the hypergraph-of-entity with the results obtained by the participants of the INEX tracks for the considered tasks.  ...  The hypergraph-of-entity was conceptually proposed as a general model for entity-oriented search. However, only the performance for ad hoc document retrieval had been assessed.  ...  For example, 'entity list completion' was a task named in TREC Entity track, but the INEX Entity Ranking track used the shorter name 'list completion' for a similar task.  ...
