This document proposes a framework to efficiently combine ontology and requirement template-based approaches in requirements engineering. It identifies different requirement templates and domain ontologies, defines transformations between templates and mappings between ontologies. A methodology integrates these approaches by analyzing similarities, relationships and conflicts. An evaluation plan will assess requirements consistency, completeness and maintainability using the integrated tool chain.

Enhancing Requirements Engineering Efficiency Using Explicit Semantics and Template-Based Mechanisms Research Preview Thomas Moser, Wikan Sunindyo, Stefan Farfeleder, Inah Omoronyia Christian Doppler Laboratory SE-Flex-AS / Institute of Computer Languages Vienna University of Technology, Austria The Irish Software Engineering Research Centre University of Limerick, Ireland
- 2. Introduction Context – Usage of ontologies and requirement templates (e.g., Boilerplates, EBNF) for support of typical requirement engineering tasks Challenges – A lot of different benefitial approaches, which are hard to combinet Objective – Provide a framework for efficient and effective combination of ontology and requirement template-based approaches 2
- 3. Boilerplates Textual requirement template (Hull, Jackson & Dick 2005) Sequence of attributes and fixed syntax elements Tool support: DODT (Farfeleder et al. 2011) – Domain ontology-supported requirement elicitation 3
- 4. EBNF Extended Bakkus-Naur-Form (Rupp 2002) Generic formal language description approach Tool support: OntRep (Moser et al. 2011) – Requirement categoriziation and consistency checking 4
- 5. Methodology to integrate approaches 1. Identify different requirement templates Define transformation between templates 2. Analyze domain ontologies used Identify similarities Identify relationships Identify conflicts among ontologies Define mappings between ontologies 3. Provide integrated tool chain based on steps 1&2 Tool-supported requirements engineering lifecycle 5
- 6. Interlinking between requirements and ontology representation 6
- 7. Evaluation Plan Requirements consistency – Focus on resolving conceptual inconsistency • e.g., the concepts of „door open“ and „door close“ Requirements completeness – Internal requirements completeness • individual requirements include entire information necessary to validate and implement them, e.g., all pre- and post-conditions – External requirements completeness • completeness of the overall set of requirements Requirement maintainability – effort required for performing typical RE maintenance tasks 7 • e.g., requirement categorization or conflict analysis
