+# Kalimat Arabic Text Corpus (Cleaned Edition)
+
+This repository provides a cleaned and consolidated version of the **Kalimat Arabic Text Corpus**, containing **18,256 Arabic news articles** collected from a diverse range of domains. The original material consisted of thousands of individual `.txt` files organised across multiple category folders. These have been reconstructed, normalised, and compiled into modern machine-learning-friendly formats.

+
+## 📚 Corpus Overview
+
+The corpus includes **20k+** articles covering a wide selection of news categories:
+
+- **Politics**
+- **Economy**
+- **Culture**
+- **Religion**
+- **Sport**
+- **Social / Society-related topics**
+- **Other sub-domains depending on the original folder structure**
+
+Each article was originally stored as *one word per line*. In this cleaned edition, all documents have been reconstructed into natural text format with proper spacing, UTF-8 encoding, and consistent metadata extraction.
+
+Although the original filenames varied widely, each document is now associated with the following fields:
+
+- **id** – numeric identifier extracted from the filename (or `-1` where none existed)
+- **filename** – original filename exactly as it appeared
+- **category** – derived from directory structure or filename
+- **year_month** – extracted from filename where possible, otherwise `"unknown"`
+- **text** – reconstructed, cleaned article text
+
 ---
+
+## 📦 Provided Formats
+
+The cleaned dataset is released in the following forms:
+
+### **1. CSV File**
+`kalimat.csv`
+
+A single UTF-8 CSV containing all metadata and article texts.
+
+### **2. JSONL File**
+`kalimat.jsonl`
+
+One JSON object per line, suitable for training modern NLP models (e.g. HuggingFace Transformers).
+
+### **3. TXT Version (Zipped)**
+`kalimat_txt.zip`
+
+All reconstructed `.txt` documents are included in a single compressed archive to avoid storing thousands of individual files in the repository. Each `.txt` file uses the original filename for easy reference.
+
+---
+
+## 🔀 Train / Validation / Test Splits
+
+The dataset has been randomly split (using a fixed seed for reproducibility) into:
+
+- **Training set** – 80%
+- **Validation set** – 10%
+- **Test set** – 10%
+
+These splits are provided as:
+
+- `kalimat_train.csv`
+- `kalimat_val.csv`
+- `kalimat_test.csv`
+
+All CSVs preserve the same column structure as the main file.
+
+### Code used for splitting (for reference)
+
+```
+python
+import pandas as pd
+from sklearn.model_selection import train_test_split
+
+df = pd.read_csv("kalimat.csv", encoding="utf-8")
+
+train_df, temp_df = train_test_split(
+    df, test_size=0.20, random_state=42, shuffle=True
+)
+
+val_df, test_df = train_test_split(
+    temp_df, test_size=0.50, random_state=42, shuffle=True
+)
+
+train_df.to_csv("kalimat_train.csv", index=False, encoding="utf-8")
+val_df.to_csv("kalimat_val.csv", index=False, encoding="utf-8")
+test_df.to_csv("kalimat_test.csv", index=False, encoding="utf-8")
