--- res: bibo_abstract: - "The use of models in requirements engineering (RE) for software-intensive embedded systems is considered beneficial. The main advantages of requirements models as documentation format are that they facilitate requirements understanding and foster automatic analysis techniques. However, natural language (NL) is still the dominant documentation format for requirements specifications, particularly in the domain of embedded systems. This is due to the facts that NL-based requirements can be used within legally binding documents and are more appropriate for reviews than models. In order to bridge the gap between both of these documentation formats, this paper proposes a model-driven RE methodology that makes use of requirements models along with a controlled natural language. The methodology combines the advantages of model-based and NL-based documentation by means of a bidirectional multi-step model transformation between both documentation formats. We illustrate the approach by means of an automotive example, explain the particular steps of the model transformation, and present performance results.\r\n@eng" bibo_authorlist: - foaf_Person: foaf_givenName: Markus foaf_name: Fockel, Markus foaf_surname: Fockel foaf_workInfoHomepage: http://www.librecat.org/personId=8472 orcid: 0000-0002-1269-0702 - foaf_Person: foaf_givenName: Jörg foaf_name: Holtmann, Jörg foaf_surname: Holtmann foaf_workInfoHomepage: http://www.librecat.org/personId=3875 orcid: 0000-0001-6141-4571 bibo_doi: 10.1109/modre.2014.6890827 dct_date: 2014^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/9781479963430 dct_language: eng dct_title: A requirements engineering methodology combining models and controlled natural language@ ...
