🧠 Original Challenge Description

Problem Statement

In this challenge, your team will support Tax Service client by designing an AI-powered agent capable of managing and interpreting deadlines from diverse input channels.

Tax professionals regularly receive time-sensitive obligations through various means:

• Scanned letters from tax authorities
• Client emails
• WhatsApp messages
• SMS
• Handwritten notes
• [...]

Your goal is to develop a solution that can ingest multimodal inputs, extract or infer relevant deadlines, and produce structured output to enhance:

• Operational efficiency
• Risk reduction
• Regulatory compliance

Many real-world deadlines are not explicitly stated. For example:

“You must reply within 5 business days from the date of this notification.”

Your AI agent must:

• Determine the base date
• Apply Portuguese legal logic (e.g., Código de Procedimento e de Processo Tributário, Código do Procedimento Administrativo)
• Produce an accurate due date

This simulates a real consulting engagement where you must deliver both a prototype and a strategic pitch to showcase its business value.

---

🗃️ Dataset

You will receive 26 multimodal inputs, including:

• 📄 scanned letters
• ✉️ plain text emails
• 📱 WhatsApp screenshots
• ✍️ handwritten notes or scribbles

Each document contains explicit or implicit tax-related deadlines, often requiring nuanced interpretation.

---

🧭 Consulting Mindset Expectations

• Legal Logic Designers
  Create a system that understands procedural rules and deadline logic from Portuguese tax law.

• Multi-Modal Integrators
  Unify text, image, and possibly audio inputs to produce actionable intelligence.

• Efficiency Catalysts
  Build tools that save time, reduce manual error, and streamline EY’s deadline management.

• Strategic Communicators
  Present your solution as a business asset that can be adopted and scaled by tax professionals.

---

📦 Deliverables

• ✅ A working prototype of your AI-powered deadline assistant
• ✅ Modular, clean, and well-documented code
• ✅ A consulting-style presentation to EY executives
• ✅ (Optional) (Optional) It’s a major plus if your presentation includes a brief live demo to showcase how the solution works in practice, you can even present over it.
• ✅ (Optional) Provide metrics like:
  • ⏱ Average processing time
  • ❌ Error rate reduction
  • 📚 Legal coverage scope

⚠️ **Important Submission Requirement** ⚠️

✅ Before the 14h00 deadline

Submit a zip folder with:

• The Google Colab notebook (with all cells run & outputs shown)

• Email it to: [email protected]
• Subject: AutoCalendarDeadlineManagerAgent – GroupName
• Include group member names in the email
• 📁 Only one submission per group

---

💡 Tips for Competitors

• Understand the Business Challenge
  Research what types of obligations exist (e.g., notifications from AT), and how deadlines are calculated.

• Design for Ambiguity
  Handle incomplete inputs, conflicting messages, and uncertainty

• Combine Rule Engines + LLMs
  Combine deterministic logic (rules, calendars, holiday lookups) with natural language understanding.

• Visualize Time
  Consider timeline visualizations like:

  • 📅 Calendar views
  • 📊 Gantt charts
  • 🚨 Deadline alerts

• Validate Relentlessly
  Address:

  • ❗ False positives
  • 🤖 Mesread text
  • 🔄 Conflicting data sources

---

🛠 Tech & Tools

🚨 Mandatory:
It is mandatory to develop the solution in Google Colab using Python.

Other than that, you are completely free to choose your own:

• 🔧 Libraries
  LangChain, Pandas, OCR(Tesseract), dateparser, calendar APIs, etc.

• 📈 Visualization Tools
  Streamlit, Dash, Power BI, etc.

• 🤖 AI Assistants
  ChatGPT, GitHub Copilot, Gemini, etc.

💥 Use any tools that enhance speed, accuracy, or creativity

---

⏱ Time Management & Rules

• ⏳ You have 4 hours to complete the challenge
  🔒 No extensions

• 🗣 Present your solution in a 5-minute pitch, simulating a client-facing demo

• 👥 Each group is allowed:

  • 1 technical support session (up to 5 minutes)
  • 1 business guidance session (up to 5 minutes)
