ABSTRACT:
A method for modeling requirements of a product includes defining an abstract use case for each feature of said product, hierarchically decomposing each abstract use case until concrete use cases are specified for each feature, depicting every actor who would use the product as communicating with a concrete use case through a boundary, and programmatically extracting requirements from the use case diagram. Programmatically extracting requirements further includes converting use case diagrams into directed acyclic graphs, where each use case corresponds to a node of a graph and each relationship between a pair of use cases is represented by a directed edge between the corresponding pair of nodes in the graph where a directed edge points from a parent node to a child node, converting the directed acyclic graph into a tree, and searching the tree to extract the requirements.
