+ # KenPOS: Kenyan Languages Part-of-Speech Tagged Dataset
35
+
36
+ ## Dataset Description
37
+
38
+ **KenPOS** is a part-of-speech (POS) tagged corpus for Kenyan languages, featuring **156,994 tokens** across four languages. The dataset provides manually annotated POS tags for low-resource Kenyan languages, enabling NLP research and applications.
39
+
40
+ ## Dataset Statistics
41

+ ## Languages & Codes
51
+
52
+ | Language / Dialect | Code | Family / Notes |
53
+ |---------------------|------|-------------------------|
54
+ | Dholuo (Luo) | dho | Nilotic (western Kenya) |

57
+ | Lulogooli (Logooli) | llg | Bantu, Luhya dialect |
58
+
59
+ ## Dataset Format
60
+
61
+ The dataset is distributed as **Parquet files** for optimal performance and compatibility:
62
+
63
+ - **Format**: Apache Parquet (columnar storage)
64
+ - **Encoding**: UTF-8
65
+ - **File naming**: `{language}/train.parquet`
66
+ - **Compatibility**: Works with `datasets` 4.0.0+ without custom loading scripts
67
+
68

69
+
70
+ ## Data Fields
71
+
72
+ Each record in the dataset contains:
73
+
74
+ - **token**: `string` - The word or token
75
+ - **pos_tag**: `string` - Part-of-speech tag (e.g., NN, V, ADJ, PUNCT)
76
+ - **sentence_id**: `int` - Unique identifier for the sentence
77
+ - **position**: `int` - Position of the token within the sentence (0-indexed)
78
+ - **filename**: `string` - Source filename from which the token was extracted
79
+
80
+ ### Example Record
81
+
82
+ ```python
83
+ {
84
+ 'token': 'Kezia',
85
+ 'pos_tag': 'NN',
86
+ 'sentence_id': 0,
87
+ 'position': 0,
88
+ 'filename': '4411_dho_pos.csv'
89
+ }
90
+ ```
91

93
+
94
+ ## Usage
95
+
96
+ ### Loading with 🤗 Datasets
97
+
98
+ **Compatible with datasets 4.0.0+** (No `trust_remote_code` needed!)
99
+
100
+ ```python
101
+ from datasets import load_dataset
102
+
103
+ # Load Dholuo POS dataset
104
+ dho = load_dataset("Kencorpus/KenPOS", "dho")
105
+
106
+ # Load Lubukusu POS dataset
107
+ lbk = load_dataset("Kencorpus/KenPOS", "lbk")
108
+
109
+ # Load Lumarachi POS dataset
110
+ lch = load_dataset("Kencorpus/KenPOS", "lch")
111
+
112
+ # Load Lulogooli POS dataset
113
+ llg = load_dataset("Kencorpus/KenPOS", "llg")
114
+
115
+ # Access the data
116
+ print(dho['train'][0])
117
+ # Output: {'token': 'Kezia', 'pos_tag': 'NN', 'sentence_id': 0, 'position': 0, 'filename': '4411_dho_pos.csv'}
118
+ ```
119
+
120
+ ### Reconstructing Sentences
121
+
122
+ ```python
123
+ from datasets import load_dataset
124
+ import pandas as pd
125
+
126
+ # Load dataset
127
+ dho = load_dataset("Kencorpus/KenPOS", "dho")
128
+ df = pd.DataFrame(dho['train'])
129
+
130
+ # Get first sentence
131
+ sentence_0 = df[df['sentence_id'] == 0].sort_values('position')
132
+ print(' '.join(sentence_0['token'].tolist()))
133
+ ```
134
+
135
+ ### Analyzing POS Tags
136
+
137
+ ```python
138
+ from datasets import load_dataset
139
+ import pandas as pd
140
+
141
+ # Load dataset
142
+ dho = load_dataset("Kencorpus/KenPOS", "dho")
143
+ df = pd.DataFrame(dho['train'])
144
+
145
+ # Count POS tag frequencies
146
+ pos_counts = df['pos_tag'].value_counts()
147
+ print(pos_counts.head(10))
148
+ ```
149
+
150
+ ---
151
+
152
+ ## POS Tag Categories
153
+
154
+ The dataset uses a variety of POS tags including:
155
+
156
+ - **NN** - Noun
157
+ - **V** - Verb
158
+ - **ADJ/Adj.** - Adjective
159
+ - **ADV/Adv** - Adverb
160
+ - **PRON** - Pronoun
161
+ - **ADP** - Adposition (preposition/postposition)
162
+ - **DET/Det.** - Determiner
163
+ - **CONJ/Conj.** - Conjunction
164
+ - **NUM** - Numeral
165
+ - **PUNCT/PUNC** - Punctuation
166
+ - And many more fine-grained categories
167
+
168
+ **Note**: Tag naming conventions may vary slightly across files (e.g., PUNCT vs PUNC, ADJ vs Adj.).
