Datasets are dumped from PostgreSQL. Some commands may not be supported by other relational database management systems. To reduce time when loading the data, it is recommended that the schema file be split so indexes are created after loading the data.
The “complete” data sets denote the original data set instead of the subset used for evaluation.
Additional evaluation revealed minor mistakes with the original IMDb qrels. To facilitate comparison with published evaluations, the original qrels remain available above. Corrected qrels: IMDb
