In requirements elicitation, there is almost always a need for the participation of stakeholders (e.g. domain experts, customers and end-users) to help requirements engineers to uncover requirements. This need leads to the problem of how the stakeholders can communicate their needs effectively, but if one addresses existing work on such communication related issues, a wide diversity of techniques is proposed to support better description and understanding, all based on face-toface communication with stakeholders [1]. The humancentred nature of these approaches creates a considerable difficulty in attempting automation of requirements elicitation. Furthermore, stakeholders often lack relevant domain and system knowledge. Modelling techniques are typically applied to analyse the domain-specific data, using the chosen modelling concepts.
