+ ### Dataset Summary
56
+
57
+ The Sesotho Ner Corpus is a Sesotho dataset developed by [The Centre for Text Technology (CTexT), North-West University, South Africa](http://humanities.nwu.ac.za/ctext). The data is based on documents from the South African goverment domain and crawled from gov.za websites. It was created to support NER task for Sesotho language. The dataset uses CoNLL shared task annotation standards.
58
+
59
+ ### Supported Tasks and Leaderboards
60
+
61
+ [More Information Needed]
62
+
63
+ ### Languages
64
+
65
+ The language supported is Sesotho.
66
+
67
+ ## Dataset Structure
68
+
69
+ ### Data Instances
70
+
71
+ A data point consists of sentences seperated by empty line and tab-seperated tokens and tags.
72
+ ```
73
+ {'id': '0',
74
+ 'ner_tags': [0, 0, 0, 0, 0],
75
+ 'tokens': ['Morero', 'wa', 'weposaete', 'ya', 'Ditshebeletso']
76
+ }
77
+ ```
78
+
79
+ ### Data Fields
80
+
81
+ - `id`: id of the sample
82
+ - `tokens`: the tokens of the example text
83
+ - `ner_tags`: the NER tags of each token
84
+
85
+ The NER tags correspond to this list:
86
+ ```
87
+ "OUT", "B-PERS", "I-PERS", "B-ORG", "I-ORG", "B-LOC", "I-LOC", "B-MISC", "I-MISC",
88
+ ```
89
+ The NER tags have the same format as in the CoNLL shared task: a B denotes the first item of a phrase and an I any non-initial word. There are four types of phrases: person names (PER), organizations (ORG), locations (LOC) and miscellaneous names (MISC). (OUT) is used for tokens not considered part of any named entity.
90
+
91
+ ### Data Splits
92
+
93
+ The data was not split.
94
+
95
+ ## Dataset Creation
96
+
97
+ ### Curation Rationale
98
+
99
+ The data was created to help introduce resources to new language - Sesotho.

+ #### Who are the source language producers?
110
+
111
+ The data was produced by writers of South African government websites - gov.za

+
113
+ [More Information Needed]
