Tarab: A Multi-Dialect Corpus of Arabic Lyrics and Poetry
The paper introduces Tarab, a large-scale open corpus comprising 2.56 million verses of Arabic song lyrics and poetry spanning fourteen centuries and multiple dialects, designed to facilitate comparative linguistic and stylistic analysis through structured metadata and baseline analytical tools.

Imagine the Arabic language as a massive, ancient library. For a long time, the computers (AI) that read this library only knew how to understand the "official" books: the news, the encyclopedias, and the formal textbooks. They were great at reading the news, but they were completely lost when it came to the colorful, messy, and emotional stuff: the songs people sing at weddings, the rap battles in the streets, and the ancient poems whispered by firelight.
Enter Tarab.
Think of Tarab not just as a database, but as a giant, magical time machine that has finally learned to listen to the whole story of Arabic creativity. The name "Tarab" itself is beautiful; it refers to that feeling of musical ecstasy or deep emotional rapture you get when a song or poem hits you right in the heart.
Here is what makes this project so special, explained simply:
1. The "Greatest Hits" of 1,400 Years
Most language collections are like a snapshot of a single day. Tarab is a 14-century movie marathon.
- The Time Travel: It starts with poetry from before the time of Islam (over 1,400 years ago) and zooms all the way forward to today's pop stars and modern poets.
- The Scale: It contains over 2.5 million lines of text. That's enough to fill a library shelf that stretches for miles. It includes everything from the grand, formal poetry of kings to the catchy, slang-filled lyrics of modern pop songs.
2. A Linguistic Melting Pot
Arabic isn't just one language; it's a family of languages.
- The Official vs. The Real: Think of Modern Standard Arabic (MSA) as the "suit and tie" version of the language—used in news and schools. Think of Dialects (like Egyptian, Gulf, or Moroccan) as the "jeans and t-shirt" version—what people actually wear and speak in their daily lives.
- The Mix: Before Tarab, AI mostly knew the "suit and tie" version. Tarab teaches the AI to understand the "jeans and t-shirt" too. It covers six major regional dialects, plus the ancient "Classical" version. It's like teaching a translator to understand not just the dictionary definition of a word, but also the slang, the jokes, and the regional accents.
3. The "Verse" is the Star
Usually, when we study language, we look at whole sentences or paragraphs. Tarab decided to zoom in on the smallest, most musical unit: The Verse.
- The Lego Analogy: Imagine a song or a poem is a giant castle made of Lego bricks. Previous studies looked at the whole castle. Tarab takes the castle apart and studies every single brick.
- Why? Because in Arabic poetry and song, the "brick" (the verse) holds the secret. It tells you the rhythm, the rhyme, and the emotion. By organizing the data verse-by-verse, researchers can compare a 1,000-year-old poem with a 2020s rap song side-by-side to see how the language has changed (or stayed the same).
4. Who Made the Music?
The collection isn't just random words; it's a "Hall of Fame."
- It features 2,598 unique creators.
- On one side, you have the Legends of the Past: Ancient poets like Al-Maarri and Al-Sharif al-Radi, who wrote centuries ago.
- On the other side, you have the Superstars of Today: Famous singers like Fayruz and Amr Diab.
- Tarab puts them in the same room, allowing us to see how a poet from the 10th century and a singer from the 21st century might use words in surprisingly similar (or very different) ways.
5. Why Do We Need This?
Think of AI as a student. If you only teach a student with news articles, they will sound like a robot reading a newspaper. They won't understand sarcasm, love songs, or the way a grandmother speaks to her grandchild.
- The Goal: Tarab gives the AI a "cultural education." It helps computers understand the soul of the language, not just the grammar.
- The Result: This helps researchers build better tools for translation, better voice assistants that understand accents, and even helps us preserve our cultural history in a digital format.
The Catch (Limitations)
Like any great project, it's not perfect yet.
- The "Blurry Date" Problem: For some ancient poems, we know they are from the "Abbasid Era," but we don't know the exact year. It's like knowing a photo is from the 1920s but not the specific day.
- No Audio: Tarab is just the words. It doesn't include the actual music or the singer's voice. It's the sheet music, not the concert recording.
The Bottom Line
Tarab is a gift to the world. It's a massive, open library that says, "We value the news, but we also value the songs, the poems, and the dialects." It bridges the gap between the ancient past and the digital future, ensuring that the rich, emotional, and diverse voice of the Arabic-speaking world is finally heard loud and clear by the machines of tomorrow.
