Political viewpoints identification (PVI) is a task in Natural Language Processing that takes political texts and recognizes the writer’s opinions towards matter. PVI reduces ambiguity by identifying underlying meaning clarifying bias margin along spectrum (bias leaning). Thus, even non-experts can better understand texts. For instance, they identify misinformation, bias, hidden agendas. In thi...

Enterprises are socio technical systems whose management involves multiple stakeholders each demanding for a distinct perspective on the enterprise. A large number of modeling languages for describing different viewpoints on an enterprise have been developed in practice and academia. These viewpoints typically reflect the areas of interest that certain stakeholders pertain in respect to the ent...

Inter-organizational business cooperations can be described from different viewpoints each fulfilling a specific purpose. Since all viewpoints describe the same system they must not contradict each other, thus, must be consistent. Consistency can be checked based on common semantic concepts of the different viewpoints. This is sufficient for equal concepts, while weakly related concepts, e.g. r...

Different viewpoin ts are related an d tied togeth er by shared design at ed phenomena. Ch oosi n g which phenomena are to be design ated an d which are shared is a fun dam ental decision about h ow we th in k th e world fits togeth er, h ow our descriptions fit toget h er, an d h ow requiremen ts fit togeth er.

Two studies examine the visual presentation of dynamic sequences. Experiment 1 tests if there are canonical viewpoints, that are especially appropriate for presentation. Participants agreed that viewpoints with 90 degree deviation between axis of sight and axis of main movement in the sequence are better than other viewpoints. Experiment 2 examines if these canonical viewpoints weaken the persp...

The use of multiple partial viewpoints is recommended for specification. We believe they also can be useful for devising strategies for testing. In this paper, we use Object-Z to formally specify concurrent Java components from viewpoints based on the separation of application and synchronisation concerns inherent in Java monitors. We then use the Test-Template Framework on the Object-Z viewpoi...
