Semantic-Based Requirements Content Management for Cloud Software

الملخص EN

Cloud Software is a software complex system whose topology and behavior can evolve dynamically in Cloud-computing environments.

Given the unpredictable, dynamic, elasticity, and on-demand nature of the Cloud, it would be unrealistic to assume that traditional software engineering can “cleanly” satisfy the behavioral requirements of Cloud Software.

In particular, the majority of traditional requirements managements take document-centric approaches, which have low degree of automation, coarse-grained management, and limited support for requirements modeling activities.

Facing the challenges, based on metamodeling frame called RGPS (Role-Goal-Process-Service) international standard, this paper firstly presents a hierarchical framework of semantic-based requirements content management for Cloud Software.

And then, it focuses on some of the important management techniques in this framework, such as the native storage scheme, an ordered index with keywords, requirements instances classification based linear conditional random fields (CRFs), and breadth-first search algorithm for associated instances.

Finally, a prototype tool called RGPS-RM for semantic-based requirements content management is implemented to provide supporting services for open requirements process of Cloud Software.

The proposed framework applied to the Cloud Software development is demonstrated to show the validity and applicability.

RGPS-RM also displays effect of fine-grained retrieval and breadth-first search algorithm for associated instance in visualization.
