+# OpenWikiTables Retrieval
+
+This dataset is part of a Table + Text retrieval benchmark. Includes queries and relevance judgments across test split(s), with corpus in 3 format(s): `corpus_linearized`, `corpus_md`, `corpus_structure`.
+
+## Configs
+
+| Config | Description | Split(s) |
+|---|---|---|
+| `default` | Relevance judgments (qrels): `qid`, `did`, `score` | `test` |
+| `queries` | Query IDs and text | `test_queries` |
+| `corpus_linearized` | Linearized table representation | `corpus_linearized` |
+| `corpus_md` | Markdown table representation | `corpus_md` |
+| `corpus_structure` | Structured corpus with `headers`, `cells`, `meta_data`. `text` field corresponds to linearized Text + Table. | `corpus_structure` |
+
+## `corpus_structure` additional fields
+
+| Field | Type | Description |
+|---|---|---|
+| `meta_data` | string | Table metadata / caption |
+| `headers` | list[string] | Column headers |
+| `cells` | list[string] | Flattened cell values |

These datasets assume answers reside as a single cell value and do not necessitate exploring over multiple cells such as aggregation, comparison, and sorting. Thus, we release Open-WikiTable, the first ODQA dataset that requires complex reasoning over tables. Open-WikiTable is built upon WikiSQL and WikiTableQuestions to be applicable in the open-domain setting. As each question is coupled with both textual answers and SQL queries, Open-WikiTable opens up a wide range of possibilities for future research, as both reader and parser methods can be applied. The dataset is publicly available."
