{"url":"/dataset/kacc","name":"KACC","full_name":null,"description_markdown":"The KACC benchmark consists of three subtasks that can be applied to knowledge graphs: knowledge abstraction, knowledge concretization and knowledge completion. \r\n\r\n- The **knowledge abstraction** subtask contains tasks of concept inference, schema prediction and concept graph completion on the two-view KG. \r\n- The **knowledge concretization** subtask requires models to do entity graph completion based on the two subgraphs. The concretization ability can be further examined by the results of long-tail entity link prediction. \r\n- The **knowledge completion** subtask consists of typical single-view knowledge graph completion tasks for each subgraph.\r\n\r\nKACC contains 999,902 entities in the entity graph, with 691 types of relations . The concept graph contains 21,293 concepts with 198 types of meta-relations. There are 2,367,971 cross-links between the two.\r\n\r\nSource: [KACC: A Multi-task Benchmark for Knowledge Abstraction, Concretization and Completion](https://arxiv.org/abs/2004.13631)","description_withheld":null,"homepage":"https://github.com/thunlp/kacc","introduced_date":"2020-04-28","introduced_date_note":null,"introduced_by":{"paper":"/paper/kacc-a-multi-task-benchmark-for-knowledge","title":"KACC: A Multi-task Benchmark for Knowledge Abstraction, Concretization and Completion","first_author":"Jie Zhou","url":null},"license":null,"modalities":[{"name":"Graphs","url":"/datasets/modality/graphs"}],"tasks":[{"name":"Knowledge Graphs","url":"/task/knowledge-graphs","datasets_with_task":"/datasets/task/knowledge-graphs"}],"languages":[],"variants":["KACC"],"data_loaders":[{"repo":"https://github.com/thunlp/kacc","url":"https://github.com/thunlp/kacc","frameworks":[]}],"num_papers_in_archive":1,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
