Grammar of Dynamic Knowledge for Collaborative Knowledge Engineering and Representation

Abstract

Constructive discussion must lead to a shared understanding. This understanding is commonly expressed as text; however, for the purposes of collaborative research, the tools of knowledge engineering/knowledge representation look more appropriate. The problem with them is that, to the present day, they are developed largely for the tasks that imply fixed relations between things and their properties, termed here as static. However, collaborative research often deals with fields of knowledge that represent changing environments where these relations cannot be considered fixed, and the tools to capture scenarios of evolution (i.e. the dynamic tools of knowledge engineering) are far from that evolved as static ones, mainly due to the lack of strict logical or mathematical foundation for representation of dynamic knowledge. This chapter presents an attempt to formulate a unified grammar to encode the knowledge of changing environments in any field of science.

Organization of a geophysical information space by using an event-bush-based collaborative tool

“…Finally, the event bush has given rise to development of a unified grammar of dynamic knowledge (Pshenichny and Mouromtsev 2015), which would bring to implementation in COLLA numerous methods used to model dynamic environments -such as Petri nets (Rogalchuk and Solomin 2015), sequence diagrams, activity diagrams, influence diagrams and many others, already tested in descriptive domains of knowledge including geosciences (Pshenichny 2014). The road to their computer-based application for the purposes of collaborative studies has been paved by the event bush method.…”
