🏛️ Indic-CIB: Citizen Information Board Dataset

A Benchmark for Multilingual Indic Scene Text & Tabular Financial Extraction

Bridging the gap between rural public governance signage and open-source Document Intelligence.

---

📌 Dataset Summary

Under major Indian public works initiatives—such as the Mahatma Gandhi National Rural Employment Guarantee Scheme (MGNREGA) and the **Pradhan Mantri Gram Sadak Yojana (PMGSY)**—local governing bodies (Gram Panchayats) are mandated to erect physical Citizen Information Boards (नागरिक सूचना पट्ट / CIB) at public asset sites.

These outdoor installations serve as the bedrock of grassroots public auditing, displaying critical civic and financial data:

• Asset Description: Details of the physical asset (e.g., roads, farm ponds, percolation tanks, check dams).
• Financial Breakdowns: Sanctioned expenditure, skilled material allocations, and unskilled manual labor funds.
• Administrative Metadata: Unique work identification codes, implementing agencies, and execution timelines.

Extracting structured data from real-world CIBs presents unique computer vision challenges: outdoor weathering, hand-painted lettering, complex tabular grids, and regional Indic typography. The Indic-CIB Dataset provides procedurally generated, ground-truth-annotated boards designed to benchmark and train Vision-Language Models (VLMs) and OCR layout pipelines for automated civic audits.

🌐 Supported Scripts & Languages

This benchmark currently spans two major linguistic families of India, covering four prominent regional languages:

Language Family	Language	Script	Region / Primary Context
Indo-Aryan	Hindi (हिन्दी)	Devanagari	Northern & Central Gram Panchayats
Indo-Aryan	Marathi (मराठी)	Devanagari	Western India (Maharashtra MGNREGS / Jalyukt Shivar)
Dravidian	Tamil (தமிழ்)	Tamil	Southern India (Tamil Nadu Rural Works)
Dravidian	Telugu (తెలుగు)	Telugu	Southern India (Andhra Pradesh & Telangana Panchayats)

🗂️ Dataset Structure & Fields

Each entry in the dataset pairs a high-resolution synthesized board image with standardized key-value metadata and raw tabular Markdown.

Field Definitions

• file_name (string): Relative file path to the board image within the repository (train/cib_...jpg).
• language (string): ISO-style language identifier (hindi, marathi, tamil, telugu).
• script (string): Writing system classification (devanagari or dravidian).
• work_name (string): Name and description of the civil works project in the native regional script.
• work_id (string): Official alphanumeric identification code assigned to the project.
• sanctioned_amount_inr (float): Total approved capital expenditure in Indian National Rupees (₹).
• labor_cost_inr (float): Component allocated for unskilled labor and wage compensation.
• material_cost_inr (float): Component reserved for raw materials and technical equipment.
• completion_date (string): Scheduled or recorded completion timestamp (DD/MM/YYYY).
• table_markdown (string): Clean Markdown table representation of the board's core financial ledger.
