Traditional UML modeling can be time-consuming—especially during early design phases—requiring hours of analysis, brainstorming, and iteration. Enter Visual Paradigm’s AI-Powered Textual Analysis Tool, a revolutionary feature that transforms a high-level idea into a structured, AI-generated UML Class Diagram in minutes.

This comprehensive guide walks you through every step of using this powerful AI-driven tool, based on the latest video tutorial (circa September 2025) and official Visual Paradigm documentation. Whether you’re a software engineer, system designer, business analyst, or student learning UML, this tool streamlines your workflow and accelerates project kickoff.

🔧 Overview: What Is AI-Powered Textual Analysis?

AI-Powered Textual Analysis is an intelligent feature within Visual Paradigm that leverages advanced natural language processing (NLP) and large language models (LLMs) to analyze a plain-text problem description and automatically generate:

Candidate UML classes
Class attributes and operations
Relationships between classes (e.g., association, inheritance, aggregation)
A fully editable UML Class Diagram

This capability allows developers and analysts to jump from idea to visual model without writing a single line of code—ideal for rapid prototyping, requirements analysis, and educational use.

✅ Ideal for:

Early-stage domain modeling

Agile sprint planning

Teaching UML to beginners

Reverse engineering from documentation

Integrating AI into SDLC workflows

📌 Prerequisites: Getting Started

Before diving in, ensure you have the following:

Requirement	Details
Software	Visual Paradigm Desktop (Professional or Enterprise edition recommended)
Download	Free 30-day trial: https://www.visual-paradigm.com/download
Internet Connection	Required (AI processing runs on cloud servers)
Access Path	`Tools > Apps` → Select Software Development category → Find Textual Analysis
Optional Integration	Visual Paradigm Online (for collaboration, export, and advanced editing)

💡 Pro Tip: Use the cloud integration to save your work and continue editing in the browser-based environment.

🔄 Step-by-Step Workflow: From Idea to Class Diagram

Follow this structured, iterative process to generate accurate and meaningful UML models using AI.

Step 1: Launch the AI Textual Analysis Tool

Open Visual Paradigm Desktop.
Navigate to:
Tools > Apps → Select Software Development tab.
Scroll to page 2 (or use the search bar) to locate Textual Analysis (AI-powered).
Click Start Now.

🖥️ The interface opens with a clean, intuitive layout:

Left panel: Input fields and controls

Right panel: Real-time results and visual feedback

Step 2: Generate or Refine the Problem Description

The AI begins by generating a detailed problem description based on your initial prompt.

🔹 Enter a Domain Prompt

Input a concise name or goal:

"Online Shopping Platform"
"Student Registration System"
"Hospital Patient Management"

🔹 Click: Generate Problem Description

The AI instantly produces a paragraph (100–150 words) summarizing the system’s purpose, stakeholders, core features, and constraints.

✅ Example Output:
“The Online Shopping Platform enables customers to browse products, add items to a shopping cart, and complete purchases via secure payment gateways. Administrators manage inventory, view order history, and generate sales reports. Each customer has a profile with personal details and shipping address. Products are categorized, with attributes like name, price, stock quantity, and description. Orders are linked to customers and contain multiple line items. The system must support user authentication, role-based access control, and an analytics dashboard for administrators.”

✅ Critical Best Practice: Edit the Generated Text

The AI-generated description is a starting point, not a final version.

🔧 Enhance it with domain-specific details:

Add: “The system must include an analytics dashboard for administrators to view usage statistics and sales trends.”

Add: “Users must be able to reset passwords via email verification.”

Add: “Orders are categorized into pending, shipped, and delivered statuses.”

✅ Why It Matters: Small edits significantly improve the quality of class extraction, attribute suggestions, and relationship detection.

Step 3: Identify Candidate Classes

Click Identify Candidate Classes.

The AI scans the text and extracts potential domain entities (nouns) and concepts.

📋 Output: List of Candidate Classes

Each entry includes:

Class Name (e.g., Customer, Product, Order)
Reason for Selection (e.g., “appears 5 times in the description”, “central to the domain”)
Brief Description (e.g., “Represents a user who buys products”)

🧠 Example:

Customer: “Frequent noun; represents a user of the system”

PaymentGateway: “Mentioned in context of transaction processing”

Inventory: “Key component for managing product availability”

✅ Review & Refine

Deselect irrelevant entries (e.g., generic terms like “system”, “data”).
Add missing ones manually (e.g., ShoppingCart, OrderStatus).

🛠️ Tip: Use this step to correct AI hallucinations—if it missed a key entity, add it now.

Step 4: Identify Class Details (Attributes & Operations)

Click Identify Class Details.

For each class, the AI proposes:

Attributes (data fields): e.g., name: String, email: String, price: Double
Operations (methods): e.g., placeOrder(), calculateTotal(), updateStock()

📊 Example Output for `Order`:

Attribute	Type	Description
`orderId`	String	Unique identifier
`orderDate`	Date	Date when order was placed
`status`	OrderStatus	Current state of the order

Operation	Parameters	Returns
`addLineItem(item: Item, quantity: int)`	Item, int	void
`calculateTotal()`	—	Double
`updateStatus(newStatus: OrderStatus)`	OrderStatus	void

✅ Review Tips:

Confirm data types (e.g., use LocalDateTime instead of Date for precision).

Adjust method names to match coding conventions (e.g., getTotal() vs calculateTotal()).

Add missing operations like cancelOrder() or applyDiscount().

Step 5: Identify Class Relationships

Click Identify Class Relationships.

The AI analyzes interactions, dependencies, and ownership patterns in the text and proposes relationships such as:

Relationship Type	Description
Association	A general link between two classes (e.g., `Customer` places `Order`)
Aggregation	“Has-a” relationship (e.g., `ShoppingCart` contains `Product`)
Composition	Stronger “owns” relationship (e.g., `Order` contains `LineItem`)
Generalization (Inheritance)	`Admin` extends `User`
Dependency	One class uses another (e.g., `PaymentService` depends on `PaymentGateway`)

📋 Example Output:

Source	Target	Type	Explanation
`Customer`	`Order`	Association	“Customer places multiple orders”
`Order`	`LineItem`	Composition	“Order contains line items”
`Admin`	`User`	Generalization	“Admin is a type of user”
`PaymentService`	`PaymentGateway`	Dependency	“Uses gateway to process payments”

✅ Verify Accuracy:

Ensure composition is used for exclusive ownership.

Use inheritance only when is-a relationships exist.

Replace weak associations with more specific roles (e.g., Order → Customer via placedBy).

Step 6: Generate the Class Diagram

Click Generate Diagram.

The tool assembles all elements into a clean, readable UML Class Diagram.

✅ Features of the Generated Diagram:

Auto-layout: Intelligent placement of classes and relationships
Expandable Details: Click any class to view attributes and operations
Editable: All elements can be modified directly in the editor
Color-coded: Differentiates between entities, interfaces, and abstract classes

🎯 You now have a fully functional, AI-generated class diagram ready for:

Further refinement

Code generation

Integration with other diagrams (e.g., Use Case, Sequence)

Documentation and team sharing

Step 7: Iterate and Refine (Recommended)

One of the most powerful aspects of this tool is its iterative design capability.

🔁 How to Iterate:

Go back to the Problem Description tab.
Modify the text:
- Add: “The system must support user roles: Customer, Admin, and Support Agent.”
- Add: “Customers can rate products after purchase.”
Re-run:
- Identify Candidate Classes
- Identify Class Details
- Identify Class Relationships
- Generate Diagram

🔄 Result: The diagram updates dynamically, reflecting new entities (UserRole, Review) and relationships (Customer → Review, Admin → SupportAgent).

🎯 Use Case: You’re designing a learning management system and realize you need to model courses, enrollments, and grades—just edit the prompt and regenerate.

Step 8: Export & Further Edit in Visual Paradigm Online
