Textual Analysis Support in Visual Paradigm for UML

Textual Analysis is a feature that assists you to perform requirement capturing and analysis. Textual Analysis is started from a problem statement. There are different types of problem statement (e.g. business process and execution procedure). Each type of problem statement provides different levels of detail of the user's requirement. The Textual Analysis in Visual Paradigm for UML can assist you to extract the problem statement and draw diagrams. In Visual Paradigm for UML, you can identify classes, use cases and actors from the problem statement.

Identify candidate class  
First of all, we will identify candidate classes from the problem statement. In other words, we identify some nouns or noun phrases that are relevant to the problem domain.

Create Data Dictionary  

After identifying enough candidate classes, it is time to create a data dictionary for these classes. A data dictionary should contain precise descriptions as well as the scope for each class.

Create UML Model  

The identified candidate classes can be used to create various models such as Actor, Use Case, Class, and Workflow. Models created will be shown in the project tree (Model Tree View). These models can then be used to create UML diagrams. In this example, we have created class diagram and use case diagram.
