To obtain generated targets that are natural but also faithful to the source table, we introduce a dataset construction process where annotators directly revise existing candidate sentences from Wikipedia. We present systematic analyses of our dataset and annotation process as well as results achieved by several state-of-the-art baselines. While usually fluent, existing methods often hallucinate phrases that are not supported by the table, suggesting that this dataset can serve as a useful research benchmark for high-precision conditional text generation.\",\n}\n```",

      "intended-use": "ToTTo is a Table-to-Text NLG task, as the paper title says. The task is as follows: Given a Wikipedia table with row names, column names and table cells, with a subset of cells highlighted, generate a natural language description for the highlighted part of the table . The table need not be exactly rectangular in that - cells can sometimes be multi-row or multi-column.\n\nAn earlier example of a Table-to-Text NLG task is [Wikibio](https://arxiv.org/abs/1603.07771) - here the inputs were Wikipedia infoboxes (from the top right corner of entity-related Wiki pages). In contrast, ToTTo mostly has Wikipedia tables from the main article content itself. In general, Table-To-Text NLG tasks can be seen as a subclass of Data-To-Text NLG tasks - where the task is to generate natural language descriptions of inputs which are in the form of structured or semi-structured data. In general, all Data-To-Text NLG tasks need not have an explicit table or other structure - e.g the input in [WebNLG](https://www.aclweb.org/anthology/W16-6626.pdf) is simply a list of triples.\n\nImportantly, ToTTo differs from earlier examples of Table-To-Text NLG in that:\n\n1. It does not suffer from the problem of divergent references - where ground truth descriptions themselves have additional information not found in the table. ToTTo overcomes this by having a multi-step annotation process to edit the initial, free-form table descriptions (which are from Wikipedia) to make them faithful, unambiguous and independent of article context.\n\n2. Since it provides **control** in the form of highlighted table cells, it prevents the problem of there being a large number of valid descriptions focussing on different parts of the table.\n",

The natural text description near the table is taken as a starting point. This is Wikipedia article text as created upto that point in time by a chain of collaborative edits from Wikipedia authors.\n2. The initial description is revised by chain of two or more annotated revisions, to make it unambiguous and faithful to a set of highlighted table cells.\n\nFrom their origin in 1), the descriptions may exhibit biases seen in Wikipedia text as mentioned above. From their revisions in 2), the descriptions may show biases originating from annotator-authored text, such as a preference for shorter descriptions since they're faster to write, or linguistic preferences influenced by the locations dominant in the annotator distribution.  (However, note that these are likely to be much reduced since the annotators here are merely revising rather than completely authoring. Moreover, each sentence goes through atleast two annotators, which acts as a check against the personal biases of a single annotator.)\n\nNaturally-occurring text is also known to suffer from other biases such as reporting bias [(Gordon and Van Durme, 2013)](https://openreview.net/forum?id=AzxEzvpdE3Wcy&noteId=vmR8qaby8fqxittps://labtomarket.files.wordpress.com/2018/01/wiki_gender_bias.pdf) - this also applies to this dataset via its origin from Wikipedia.\n\n"

There are 693 different table sizes, ranging from 2 to 15834 cells.\n\n| Table size      |Frequency English|\n|-----------------|-----------------|\n| 2               |             71  |\n| 3               |             52  |\n| 4               |             36  |\n| 5               |             41  |\n| 6               |            144  |\n| 7               |             47  |\n| 8               |             59  |\n| 9               |            105  |\n| 10              |            162  |\n| 11              |             36  |\n| 12              |            158  |\n| 13              |             35  |\n| 14              |             79  |\n| 15              |            136  |\n| 16              |            111  |\n| 17              |             48  |\n| 18              |            123  |\n| 19              |             29  |\n| 20              |            112  |\n| 21              |             91  |\n| 22              |             17  |\n| 23              |              7  |\n| 24              |            169  |\n| 25              |             56  |\n| 26              |             12  |\n| 27              |             40  |\n| 28              |             77  |\n| 29              |              7  |\n| 30              |            122  |\n| 31              |              4  |\n| 32              |             49  |\n| 33              |             21  |\n| 34              |              7  |\n| 35              |            103  |\n| 36              |            131  |\n| 37              |             10  |\n| 38              |              6  |\n| 39              |             26  |\n| 40              |            110  |\n| 41              |              1  |\n| 42              |             54  |\n| 43              |              6  |\n| 44              |             47  |\n| 45              |             79  |\n| 46              |              4  |\n| 47              |              2  |\n| 48              |            114  |\n| 49              |             18  |\n| 50              |             55  |\n| 51              |             11  |\n| 52              |             43  |\n| 54              |             80  |\n| 55              |             73  |\n| 56              |             64  |\n| 57              |             12  |\n| 58              |              1  |\n| 60              |            114  |\n| 61              |              4  |\n| 63              |             39  |\n| 64              |             36  |\n| 65              |             62  |\n| 66              |             48  |\n| 67              |              1  |\n| 68              |             36  |\n| 69              |              6  |\n| 70              |             81  |\n| 72              |             76  |\n| 73              |              1  |\n| 74              |              1  |\n| 75              |             44  |\n| 76              |             33  |\n| 77              |             30  |\n| 78              |             66  |\n| 79              |              1  |\n| 80              |             83  |\n| 81              |             12  |\n| 82              |              1  |\n| 84              |             80  |\n| 85              |             25  |\n| 86              |              1  |\n| 87              |              3  |\n| 88              |             35  |\n| 90              |             78  |\n| 91              |             18  |\n| 92              |             22  |\n| 93              |              5  |\n| 94              |              2  |\n| 95              |             31  |\n| 96              |             50  |\n| 98              |             11  |\n| 99              |             14  |\n| 100             |             48  |\n| 102             |             24  |\n| 104             |             29  |\n| 105             |             36  |\n| 106             |              2  |\n| 108             |             51  |\n| 110             |             31  |\n| ...8000+        |   (up to 10)    |\n\n5. We also created three splits based on the subset of test examples in pages about people.\nWe then used the structured information in WikiData to identify the following information:\n\n-  gender (male, and female),\n- nationality grouped by continent (Africa, Asia, Europe, North America, Oceania, and South America)\n- ethnicity (African American and all USA)\n\nThe categories within gender, ethnicity, and nationality were chosen based on data availability; The ToTTo dataset includes mostly tables that do not focus on people. As a result, only seven people in the original test set are marked as having a non-binary gender. Similar sparsity informed the grouping of nationalities by continent \u2013 only 19 countries are represented by more than 10 people in the test set. In case a person has citizenships across multiple continents, we may include the person in any of the included continents.\n\nFinally, ethnicity is very sparsely annotated in WikiData; only 150 test examples in ToTTo have this information and 128 of these are African Americans. We thus are unable to compare the performance on, e.g., Yoruba or Punjabi people, both of which have fewer than five instances. Another caveat here is that only 21 of the 128 people are female. We thus compare the African American population to results on a subset that includes all US citizens.\n\n\n",

      "research-pointers": "- The highest spot on the leaderboard is currently held by an anonymous method, with BLEU=49.2, PARENT=58.7 and BLEURT=0.249 on the _Overall_ test set.\n- The **highest scoring non-anonymous** method is the T5-based method of [Kale, 2020](https://arxiv.org/abs/2005.10433). This method uses a simple row-major linearization scheme to convert the table (it chooses only the highlighted cells and ignores the other cells - table titles and section titles are prefixed at the start of the respective section table) to a flat string. The linearized input - output description pairs from training examples are then used to finetune T5, with BLEU being used as the dev metric to pick checkpoints, and beam search with beam size 10 being the decoding method.\n\n    Though the best numbers from this method are naturally from the largest T5-pretrained architecture (T5-3B), the paper shows improvements over the next-highest BERT-to-BERT method even when using T5-Base or T5-Small, which have the same and lesser parameters than BERT-to-BERT respectively.\n\n- The [Supplementary Repo](https://github.com/google-research/language/tree/master/language/totto) provides several useful modules to get started with for new approach implementation:\n\n    1. Code for the particular preprocessing / linearization scheme used to linearize the tables into flat sequences for the baseline approaches described in the paper has been described and shared [herein](https://github.com/google-research/language/tree/master/language/totto#baseline-preprocessing)\n\n    2. An [evaluation script](https://github.com/google-research/language/tree/master/language/totto#running-the-evaluation-scripts-locally) for locally scoring BLEU and PARENT system outputs on dev (or train) sets. Since BLEURT is a model-based metric, a [slightly separate](https://github.com/google-research/language/tree/master/language/totto#running-the-evaluation-scripts-locall://github.com/google-research/language/tree/master/language/totto#computing-the-bleurt-score) set of instructions is provided to evaluate on the same.\n",
