+ # malagasy-sentence
2
+
3
+ ## Overview
4
+ This dataset consists of clean, structured **sentences** extracted via Optical Character Recognition (OCR) from approximately **1GB of Malagasy thesis documents**. These documents were collected based on educational, cultural, and linguistic themes using the following keywords:
5
+
6
+ **"sekoly, boky, fampianarana, fiangonana, fanabeazana, tontolo, gazety, asa, tononkalo, faritra, teny, fiteny, soratra, poeta, tantara, literatiora, fomba"**
7
+
8
+ The dataset is saved in **CSV format**, and is particularly useful for NLP tasks involving **sentence-level modeling** in Malagasy — a low-resource language.
9
+
10
+ ## Dataset Details
11
+ - **Language**: Malagasy
12
+ - **Source**: OCR'd academic thesis documents in PDF form
13
+ - **Download URL**: [Université d’Antananarivo Thesis Library](http://www.biblio.univ-antananarivo.mg/theses2/)
14
+ - **Collection Keywords**: `sekoly`, `boky`, `fampianarana`, `fiangonana`, `fanabeazana`, `tontolo`, `gazety`, `asa`, `tononkalo`, `faritra`, `teny`, `fiteny`, `soratra`, `poeta`, `tantara`, `literatiora`, `fomba`
15
+ - **Format**: CSV
16
+ - **Column(s)**: `sentence`
17
+ - **Granularity**: Each row contains a **single sentence**.
18
+
19
+ ## Preprocessing Pipeline
20
+ The following steps were used to clean and normalize the raw OCR text:
21
+
22
+ 1. **Unicode normalization** using NFKC to standardize characters.
23
+ 2. **URL removal** to eliminate web links from scanned content.
24
+ 3. **Quote standardization**, converting straight quotes to typographic quotes.
25
+ 4. **Non-alphanumeric character removal**, excluding allowed punctuation.
26
+ 5. **Punctuation spacing**, ensuring correct spacing after commas, periods, etc.
27
+ 6. **Removal of structured markers** such as:
28
+ - Numbered headings (`1.`, `1.1.1`, etc.)
29
+ - Lettered sections (`a.`, `b-1`, etc.)
30
+ - Roman numeral references (`IV-2`, etc.)
31
+ 7. **Consecutive punctuation cleanup** to reduce noise from OCR errors.
32
+ 8. **Paragraph structure fixes**:
33
+ - Merging broken paragraphs that were split across lines or pages.
34
+ - Removing paragraphs shorter than 10 characters.
35
+ 9. **Sentence segmentation** to split structured paragraphs into **individual sentences**.
36
+ 10. **Whitespace normalization** to remove extra spaces and line breaks.
37
+ 11. ** Deduplicated and Shuffled **
38
+
39
+ These steps were applied **iteratively** for high-quality, standardized sentence-level data.
40
+
41
+ ## Potential Applications
42
+ This dataset is well-suited for:
43
+ - **Sentence-level language modeling** and generation in Malagasy
44
+ - **Fine-tuning multilingual NLP models** on Malagasy
45
+
46
+ ## Limitations
47
+ - Some sentences may contain **French words or phrases**, as they are sometimes used in citations or quoted material within the thesis documents.
48
+ - OCR errors may still be present in some complex layouts or highly degraded scans.
49
+
50
+ ## Usage
51
+ To load this dataset using the Hugging Face `datasets` library:
52
+
53
+ ```python
54
+ from datasets import load_dataset
55
+
56
+ dataset = load_dataset('Lo-Renz-O/malagasy-sentence')
57
+ print(dataset['train'][0])
58
+ ```

+ ## Contribution
60
+ We welcome contributions to improve this dataset! If you have suggestions or additional Malagasy text sources, feel free to open a discussion or submit data on Hugging Face.
