Ontology-Assisted Systems Engineering Process with Focus in the Requirements Engineering Process

Toward a better integration of requirements and model‐based specifications

“…It is possible to train ontologies directly with requirements documents instead of general texts on the domain 44,45 . Fraga et al 46 propose to generate templates from ontologies, in order to provide more flexibility. Although all these works are interesting, it seems difficult in practice to obtain enough training material to get good results.…”

“…Regarding the second question, our answer is much more positive. Several tools exist that help the analyst to write requirements in logic‐based controlled natural language, eg, RAT 46 and PROPEL 56 . Our approach could benefit from inputs of these efforts.…”

A language proposition for system requirements

“…One approach for writing requirements focuses on the use of templates (also called "boilerplates") [6] [7]. An example of template could be "The <system> shall <do something> with <a given level of performance> in <a given context>".…”

“…In the work of Fraga et al [7], the templates can be generated from ontologies, which allows more flexibility. The case study presented by Kaindl [10] could also be considered as using ontologies, even if the word itself is not mentioned.…”

A language for writing system specifications in an aeronautical context

“…We however did not find a lot of works focusing on the precise needs presented here, even if there is a real industrial demand for such methods and tools. The CRYSTAL [12] project is focusing on this aspect: ontologies and patterns are used to obtain less ambiguous and more processable requirements [13]. We believe our work is different and complete these efforts by proposing a more flexible approach than static, predefined patterns and by requiring less effort than the construction of a complete ontology before beginning to write a specification.…”
