The DBpedia-Entity v2 Test Collection

The DBpedia-Entity collection a standard test set for entity search. It is meant for evaluating retrieval systems that return a ranked list of entities in response to a free text user query. The first version of the collection (DBpedia-Entity v1) was released in 2013, based on DBpedia v3.7. It was created by assembling search queries from a number of entity-oriented benchmarking campaigns (TREC, INEX, SemSearch, etc.) and mapping relevant results to DBpedia. An updated version of the collection, DBpedia-Entity v2, has been released in 2017, as a result of a collaborative effort between the IAI group of the University of Stavanger, the Norwegian University of Science and Technology, Wayne State University, and Carnegie Mellon University. It has been published at the 40th International ACM SIGIR Conference on Research and Development in Information Retrieval (SIGIR’17), where it received a Best Short Paper Honorable Mention Award.

DBpedia-Entity v2 is based on DBpedia version 2015-10 (specifically on the English subset) and comes with graded relevance assessments collected via crowdsourcing. We also report on the performance of a selection of retrieval methods using this collection.

The collection is available here.
