Textual analysis

To identify the objects and classes in Software modeling, a textual analysis is performed: 
"One of the first steps is to create scenarios that in aggregate model the various dimensions of the problem domain. From those scenarios, you can identify potential objects, behaviors, and attributes. For example, select the nouns from the problem domain as possible future objects. The next logical step is to identify the verbs and verb phrases in the problem domain. These are potential behaviors. Finally, from the scenarios, identify the adjectives or other descriptive phrases that are potential attributes."

Performing the analysis on the higher level of abstraction, apparently it produces what Attribute-Component-Capability (ACC) model operates with: components (nouns), capabilities (verbs) and attributes.
