55
+ ### Dataset Summary
56
+
57
+ From the homepage:
58
+
59
+ *This shared task (part of WMT20) will build on its previous editions to further examine automatic methods for estimating the quality of neural machine translation output at run-time, without relying on reference translations. As in previous years, we cover estimation at various levels. Important elements introduced this year include: a new task where sentences are annotated with Direct Assessment (DA) scores instead of labels based on post-editing; a new multilingual sentence-level dataset mainly from Wikipedia articles, where the source articles can be retrieved for document-wide context; the availability of NMT models to explore system-internal information for the task.*
60
+
61
+ *The goal of this task 3 is to predict document-level quality scores as well as fine-grained annotations.*
62
+
63
+ *Each document has a product title and its description, and is annotated for translation errors according to the MQM framework. Each error annotation has:*
64
+ - ***Word span(s).*** *Errors may consist of one or more words, not necessarily contiguous.*
65
+ - ***Severity.*** *An error can be minor (if it doesn't lead to a loss of meaning and it doesn't confuse or mislead the user), major (if it changes the meaning) or critical (if it changes the meaning and carry any type of implication, or could be seen as offensive).*
66
+ - ***Type.*** *A label specifying the error type, such as wrong word order, missing words, agreement, etc. They may provide additional information, but systems don't need to predict them.*
67
+
68
+ ### Supported Tasks and Leaderboards
69
+
70
+ From the homepage:
71
+
72
+ *Submissions will be evaluated as in Task 1, in terms of Pearson's correlation between the true and predicted MQM document-level scores. Additionally, the predicted annotations will be evaluated in terms of their F1 scores with respect to the gold annotations. The [official evaluation scripts](https://github.com/sheffieldnlp/qe-eval-scripts) are available.*
73
+
74
+ ### Languages
75
+
76
+ There is a single language pair in the dataset: English (`en`) - French (`fr`).

+ ### Data Instances
81
+
82
+ An example looks like this:

89
+ 'mt_tokenized': ['Roues de rechange Razor Scooter sertie de roulements', 'Roues de scooter w / roulements-bleu'],
90
+ 'annotations': {
91
+ 'segment_id': [[0], [1], [1], [0, 0], [0], [1], [1]],
92
+ 'annotation_start': [[42], [19], [9], [0, 32], [9], [17], [30]],
93
+ 'annotation_length': [[10], [10], [7], [5, 6], [8], [1], [4]],
94
+ 'severity': [0, 0, 0, 0, 0, 1, 0],
95
+ 'severity_weight': [1.0, 1.0, 1.0, 1.0, 1.0, 5.0, 1.0]

100
+ 'first_token': [[7], [5], [2], [0, 5], [2], [3], [5]],
101
+ 'last_token': [[7], [5], [2], [0, 5], [2], [3], [5]],
102
+ 'segment_id': [[0], [1], [1], [0, 0], [0], [1], [1]],
103
+ 'severity': [0, 0, 0, 0, 0, 1, 0],
104
+ 'token_after_gap': [[-1], [-1], [-1], [-1, -1], [-1], [-1], [-1]]
105
+ },
106
+ 'token_index': [[[0, 5], [6, 2], [9, 8], [18, 5], [24, 7], [32, 6], [39, 2], [42, 10]], [[0, 5], [6, 2], [9, 7], [17, 1], [18, 1], [19, 15]]],
107
+ 'total_words': 16
108
+ }
109
+ ```
110
+
111
+ ### Data Fields
112
+
113
+ - `document_id`: the document id (name of the folder).
114
+ - `source_segments`: the original source text, one sentence per line (i.e. per element of the list).
115
+ - `source_tokenized`: a tokenized version of `source_segments`.
116
+ - `mt_segments`: the original machine-translated text, one sentence per line (i.e. per element of the list).
117
+ - `mt_tokenized`: a tokenized version of `mt_segments`. Default value is `[]` when this information is not available (it happens 3 times in the train set: `B0001BW0PQ`, `B0001GS19U` and `B000A6SMJ0`).
118
+ - `annotations`: error annotations for the document. Each item of the list corresponds to an error annotation, which in turn may contain one or more error spans. Error fields are encoded in a dictionary. In the case of a multi-span error, multiple starting positions and lengths are encoded in the list. Note that these positions points to `mt.segments`, not `mt_tokenized`.
119
+ - `segment_id`: List of list of integers. Id of each error.
120
+ - `annotation_start`: List of list of integers. Start of each error.
121
+ - `annotation_length`: List of list of intergers. Length of each error.
122
+ - `severity`: List of one hot. Severity category of each error.
123
+ - `severity_weight`: List of floats. Severity weight of each error.
124
+ - `category`: List of one hot. Category of each error. See the 45 categories in `_ANNOTATION_CATEGORIES_MAPPING`.
125
+ - `token_annotations`: tokenized version of `annotations`. Each error span that contains one or more tokens has a "first token" and "last token". Again, multi-span errors have their first and last tokens encoded in a list. When a span is over a gap between two tokens, the "first" and "last" positions are `-1` (encoded as `-` in the original data), and instead the `token_after_gap` column points to the token immediately after the gap. In case of a gap occurring at the end of the sentence, this value will be equal to the number of tokens.
126
+ - `segment_id`: List of list of integers. Id of each error.
127
+ - `first_token`: List of list of integers. Start of each error.
128
+ - `last_token`: List of list of intergers. End of each error.
129
+ - `token_after_gap`: List of list of integers. Token after gap of each error.
130
+ - `severity`: List of one hot. Severity category of each error.
131
+ - `category`: List of one hot. Category of each error. See the 45 categories in `_ANNOTATION_CATEGORIES_MAPPING`.
132
+ - `token_index`: a mapping of tokens to their start and ending positions in `mt_segments`. For each token, a start and end value are encoded in a list of length 2, and all tokens represent one item in the list.
133
+ - `total_words`: total number of words in the document

31
+ This shared task (part of WMT20) will build on its previous editions
32
+ to further examine automatic methods for estimating the quality
33
+ of neural machine translation output at run-time, without relying
34
+ on reference translations. As in previous years, we cover estimation
35
+ at various levels. Important elements introduced this year include: a new
36
+ task where sentences are annotated with Direct Assessment (DA)
37
+ scores instead of labels based on post-editing; a new multilingual
38
+ sentence-level dataset mainly from Wikipedia articles, where the
39
+ source articles can be retrieved for document-wide context; the
40
+ availability of NMT models to explore system-internal information for the task.
41
+
42
+ The goal of this task 3 is to predict document-level quality scores as well as fine-grained annotations.
