      Conference report
      Open Access
      i* is a well known goal modeling framework, developed by a large and geographically dispersed research community. Currently, i* users tend to ascribe different and conflicting meanings to its constructs, leading to a non­ ...

    • Applying a foundational ontology to analyze means-end links in the i* framework

      Conference report
      Open Access
      The i* community has raised several main dialects and dozens of variations in the definition of the i* language. Differences may be found related not just to the representation of new concepts but to the very core of the ...

      Conference report
      Open Access
      The i* framework is a renowned Requirements Engineering approach. This work is part of an ongoing effort to provide ontological interpretations for the i* core concepts. With this, we aim at proposing a more uniform use ...
