Kurzfassung englisch:
The verification of Extended Entity Relationship (EER) diagrams and other conceptual models that capture the design
of information systems is crucial to ensure reliable systems.
To scale up verification processes to larger groups of experts,
Human Computation techniques were used focusing primarily on closed tasks, which constrain the number and variety of
reported defects in favor of easy aggregation of derived judgements. To address this limitation of closed tasks, in this paper,
we investigate EER verification (as instance of a broader family of model verification problems) with open tasks to extend
the range of collected results. We also address the challenge
of aggregating results of open tasks by proposing a followup HC task for defect validation. We evaluate our approach
for HC-based EER Verification with open tasks in a set of
experiments conducted with junior developers and show that
(1) open tasks allow collecting a variety of insights that go
beyond a manually built gold standard while still leading to
good performance (F1=60%) and (2) HC-based validation
can be reliably used for validating the results of open tasks
(F1=84% compared to expert validation).
