Abstract
The processes involved in requirements engineering are some of the most, if not the most, important steps in systems development. The need for well-defined requirements remains a critical issue for the development of any system. Describing the structure and behavior of a system could be proven vague, leading to uncertainties, restrictions, or improper functioning of the system that would be hard to fix later. In this context, this article proposes SENSE, a framework based on standardized expressions of natural language with well-defined semantics, called boilerplates, that support a flow-down procedure for requirement management. This framework integrates sets of boilerplates and proposes the most appropriate of them, depending, among other considerations, on the type of requirement and the developing system, while providing validity and completeness verification checks using the minimum consistent set of formalities and languages. SENSE is a consistent and easily understood framework that allows engineers to use formal languages and semantics rather than the traditional natural languages and machine learning techniques, optimizing the requirement development. The main aim of SENSE is to provide a complete process of the production and standardization of the requirements by using semantics, ontologies, and appropriate NLP techniques. Furthermore, SENSE performs the necessary verifications by using SPARQL (SPIN) queries to support requirement management.
Highlights
These concepts are entities mapped onto the semantic model of the aforementioned ontology
Common components of ontologies include individuals, instances, classes, attributes, relations, functions, restrictions, rules, and axioms as well as events. In this context, we have developed two ontologies, the first refers to an eshop software system called Shopy ontology, while the other refers to an ATM system, along with the necessary general ontology for the abstract description of the system
This could be achieved as SENSE allows engineers to analyze their projects from the first design phase while paying attention to different sustainability dimensions, using an ontology and the validation checks provided by SENSE
Summary
Requirements engineering is one of the most important, if not the most important, stages in systems development Whether it is software or hardware systems or embedded systems, the need for well-defined requirements remains the same. Even to this day, most of the projects rely on natural language specifications with loose guidelines. In order to understand how important specifications are, it is enough to think that an incomplete or misinterpreted description can lead to an application restriction or even to improper functioning of the system that will be difficult to fix later [1,2] To this end, in many cases the requirements text is accompanied by a free-form text in an attempt to help clarify the requirements
