-\section{Introduction}
-
-The rapid advancement of Large Language Models (LLMs) has revolutionized natural language processing, enabling unprecedented capabilities in text generation, understanding, and reasoning \cite{brown2020language, chowdhery2022palm}. However, these breakthroughs have predominantly benefited high-resource languages, particularly English, while low-resource languages like Arabic continue to face significant challenges due to limited availability of large-scale, high-quality training corpora \cite{abdelali2024arabic}.
-
-Arabic, spoken by over 400 million people worldwide and ranking as the fifth most spoken language globally, presents unique linguistic challenges for NLP applications. The morphological richness, right-to-left script, diacritical marks, and dialectal variations make Arabic text processing particularly complex \cite{habash2010introduction}. Despite its global significance, Arabic remains underrepresented in the development of state-of-the-art language models, primarily due to the scarcity of comprehensive, clean, and well-structured datasets.
-
-Recent surveys on Arabic NLP datasets reveal a critical gap: while datasets exist for specific tasks such as sentiment analysis, named entity recognition, and question answering \cite{antoun2020arabert}, there is a notable absence of large-scale, general-purpose text corpora suitable for pre-training modern LLMs \cite{fanar2024review}. Existing Arabic corpora often suffer from quality issues including incomplete preprocessing, presence of non-Arabic text, formatting artifacts, and insufficient scale for contemporary deep learning models.
-
-This paper presents ArabicText-Large, a meticulously curated dataset developed at Al Hussein Technical University to address these limitations. Our contributions are threefold:
-
-\begin{itemize}
-    \item We present a large-scale, high-quality Arabic corpus comprising 743,288 articles with 244 million words, representing one of the largest publicly available Arabic text collections for LLM training.
-
-    \item We introduce a comprehensive multi-stage processing pipeline that employs advanced cleaning techniques, quality filtering mechanisms, and validation protocols to ensure dataset integrity and linguistic quality.
-
-    \item We provide detailed statistical analysis, quality assessment metrics, and comparative evaluation against existing Arabic datasets, demonstrating the superior characteristics of our corpus.
-\end{itemize}
-
-The remainder of this paper is organized as follows: Section II reviews related work on Arabic datasets and preprocessing methods. Section III describes our data collection and processing methodology. Section IV presents comprehensive statistical analysis and quality metrics. Section V compares our dataset with existing Arabic corpora. Section VI discusses applications and future work, and Section VII concludes the paper.
-
-\section{Related Work}
-
-\subsection{Arabic NLP Datasets}
-
-The landscape of Arabic NLP has evolved significantly over the past decade, with several notable dataset contributions. The Arabic Gigaword corpus \cite{parker2011arabic} represented an early milestone, containing over 848 million words from newswire sources. However, its focus on formal news text limits its applicability for general-purpose language modeling.
-
-More recently, the OSCAR corpus \cite{ortiz2019asynchronous} included Arabic text as part of its multilingual collection, comprising approximately 22 billion words. While substantial in size, OSCAR's automated collection process results in varying quality levels and significant noise requiring extensive post-processing.
-
-The CC-100 dataset \cite{conneau2020unsupervised} provides monolingual data for 100+ languages, including Arabic, with approximately 17 billion words. Similarly, mC4 \cite{xue2021mt5} offers Arabic text extracted from Common Crawl, containing around 42 billion words. Despite their scale, both datasets exhibit quality concerns including code-mixing, transliteration inconsistencies, and webpage artifacts.
-
-Recent specialized efforts include AraSpider \cite{alyafeai2020araspider} for question answering (200K samples), AraBERT pre-training corpus \cite{antoun2020arabert} (70M sentences), and the 101 Billion Arabic Words Dataset \cite{alkhamissi2024101billion} which represents the largest collection to date but faces accessibility and quality standardization challenges.
-
-\subsection{Arabic Text Preprocessing Methods}
-
-Arabic text preprocessing requires specialized techniques due to the language's unique characteristics. Habash \cite{habash2010introduction} identified key challenges including orthographic inconsistency, morphological complexity, and diacritization variability.
-
-Recent preprocessing approaches employ multi-stage pipelines. The TNKEEH library \cite{tnkeeh2021} provides normalization and cleaning tools specifically designed for Arabic. Research by Alyafeai et al. \cite{alyafeai2021preprocessing} demonstrated that proper preprocessing can improve downstream task performance by 15-20\%.
-
-Studies on Arabic social media text preprocessing \cite{almiman2020preprocessing, alharbi2021preprocessing} revealed that effective cleaning includes removing diacritics, normalizing Arabic letters, handling elongation, and removing non-Arabic characters. However, these techniques must be carefully balanced to preserve linguistic information crucial for language modeling.
-
-\subsection{Quality Assessment Metrics}
-
-Dataset quality assessment for Arabic NLP typically considers multiple dimensions: linguistic purity (Arabic character ratio), content diversity (topic distribution), text coherence (sentence structure), and vocabulary richness (unique word ratio) \cite{alkhamissi2024dataset}.
-
-The AlGhafa benchmark \cite{alghafa2023} and ABBL evaluation framework \cite{abbl2024} provide standardized metrics for Arabic dataset quality, considering factors such as dialectal coverage, domain distribution, and text complexity. These frameworks inform our quality assessment methodology.
-
-\section{Methodology}
-
-\subsection{Data Collection}
-
-Our data collection process targeted high-quality Arabic content from reliable, peer-reviewed sources. We employed a systematic scraping methodology focusing on encyclopedic content that undergoes community review and editorial oversight, ensuring factual accuracy and linguistic quality across diverse topics.
-
-The collection process involved:
-\begin{enumerate}
-    \item \textbf{Source Selection}: We selected sources known for comprehensive coverage, quality control mechanisms, and regular content updates by expert contributors. Priority was given to platforms with established editorial standards and multilingual support.
-    \item \textbf{Article Retrieval}: We systematically extracted articles across multiple domains including science, history, geography, culture, and biography, ensuring broad topic coverage.
-    \item \textbf{Format Preservation}: Raw content was converted to structured text while preserving paragraph boundaries and semantic structure, maintaining document organization.
-    \item \textbf{Metadata Extraction}: We captured article identifiers, titles, source URLs, and timestamps for traceability and provenance tracking.
-\end{enumerate}
-
-The initial collection yielded 1,161,600 articles totaling approximately 5.35 GB of raw data before processing.
-
-\subsection{Text Preprocessing Pipeline}
-
-We developed a comprehensive multi-stage preprocessing pipeline to transform raw encyclopedic content into high-quality training data suitable for LLM training. The complete workflow is illustrated in Figure \ref{fig:pipeline}.
-
-\subsubsection{Stage 1: Structural Artifact Removal}
-
-Encyclopedic web content contains numerous structural elements unsuitable for language model training. Our cleaning process removes:
-
-\begin{itemize}
-    \item \textbf{Reference Markers}: Numerical citations [1], [2], [1-5], etc.
-    \item \textbf{Template Structures}: Infoboxes, navigation boxes, and template syntax
-    \item \textbf{Metadata Elements}: Edit history, version notices, category tags
-    \item \textbf{Navigation Components}: "See also", "References", "External links" sections
-    \item \textbf{Media Elements}: Image captions, file references, gallery markup
-    \item \textbf{Coordinate Data}: Geographic coordinates and mapping information
-\end{itemize}
-
-We employ comprehensive regex patterns to identify and remove these artifacts. Table \ref{tab:patterns} summarizes the key pattern categories.
-
-\begin{table}[htbp]
-\caption{Structural Artifact Removal Patterns}
-\label{tab:patterns}
-\centering
-\begin{tabular}{@{}ll@{}}
-\toprule
-\textbf{Category} & \textbf{Pattern Examples} \\ \midrule
-References & \texttt{[\textbackslash d+]}, \texttt{[\textbackslash d,\textbackslash s]+} \\
-Templates & \texttt{\{\{.*?\}\}}, \texttt{معلومات} \\
-Navigation & \texttt{انظر أيضا}, \texttt{مراجع} \\
-Media & \texttt{ملف:}, \texttt{File:}, \texttt{صورة:} \\
-Links & \texttt{https?://}, \texttt{www.} \\
-\bottomrule
-\end{tabular}
-\end{table}
-
-\subsubsection{Stage 2: Arabic Text Normalization}
-
-Arabic-specific normalization ensures consistency and removes non-linguistic artifacts:
-
-\begin{enumerate}
-    \item \textbf{Diacritic Removal}: All Arabic diacritical marks are removed as they are rarely used consistently and can introduce noise.
-
-    \item \textbf{Character Normalization}: Alef variants normalized, Hamza standardized when appropriate.
-
-    \item \textbf{Punctuation Standardization}: Arabic punctuation preserved while removing duplicate marks.
-
-    \item \textbf{Whitespace Normalization}: Multiple spaces reduced to single space, multiple line breaks condensed to double breaks for paragraph separation.
-\end{enumerate}
-
-\subsubsection{Stage 3: Quality Filtering}
-
-We implement strict quality criteria to ensure only high-quality articles are retained:
-
-\begin{enumerate}
-    \item \textbf{Length Filtering}:
-    \begin{itemize}
-        \item Minimum: 100 characters (removes stubs)
-        \item Maximum: 50,000 characters (removes lists/tables)
-    \end{itemize}
-
-    \item \textbf{Arabic Content Ratio}: Articles must contain $\geq$70\% Arabic characters to ensure linguistic purity.
-
-    \item \textbf{Sentence Structure}: Minimum 3 sentences required to ensure substantive content.
-
-    \item \textbf{Stub Detection}: Articles containing stub indicators with length $<$200 words are removed.
-\end{enumerate}
-
-\subsubsection{Stage 4: Content Quality Assessment}
-
-Each article undergoes multi-dimensional quality scoring based on:
-
-\begin{enumerate}
-    \item \textbf{Structural Quality}: Paragraph count, sentence variety, formatting consistency
-    \item \textbf{Linguistic Quality}: Vocabulary richness, word diversity, sentence complexity
-    \item \textbf{Information Density}: Unique word ratio, content-to-noise ratio
-    \item \textbf{Coherence}: Title-text relevance, topical consistency
-\end{enumerate}
-
-Articles scoring below 40\% on the combined quality metric are excluded. The scoring formula is:
-
-\begin{equation}
-Q_{score} = 0.25S + 0.30L + 0.25I + 0.20C
-\end{equation}
-
-where $S$, $L$, $I$, $C$ represent structural, linguistic, information, and coherence scores respectively.

-\end{figure}
-
-\subsection{Deduplication and Validation}
-
-To ensure corpus uniqueness:
-
-\begin{enumerate}
-    \item \textbf{Exact Deduplication}: Identical articles removed using hash-based comparison
-    \item \textbf{Near-Duplicate Detection}: MinHash LSH algorithm identifies similar articles ($>$95\% similarity)
-    \item \textbf{Format Validation}: JSONL structure verified, UTF-8 encoding confirmed
-    \item \textbf{Statistical Validation}: Outlier detection for suspicious patterns
-\end{enumerate}
-
-\subsection{Dataset Structuring}
-
-The final dataset is structured in JSONL format with the following schema:
-
-\begin{verbatim}
+```json
 {
-  "id": "unique_identifier",
-  "title": "article_title",
-  "text": "cleaned_content",
+  "id": "unique_article_identifier",
+  "title": "Article Title in Arabic",
+  "text": "Full cleaned Arabic text content...",
   "url": "source_url",
   "metadata": {
     "language": "ar",
-    "source": "Wikipedia",
-    "processing_date": "ISO8601",
-    "quality_score": float
