Process

What is a Process?

1. Process is a naturally occurring or designed sequence of changes of properties or attributes of an object or system. [Ref: Ref: Glossary of Systems Theory]
   1. Process model: An organized arrangement of systems concepts and principles that portray the behavior of a system through time.
2. Process is a sequence of operations and involved events, taking up time, space, expertise or other resources, which lead to the production of some outcome. [Gomez-Perez2010]
   1. A process can be considered as a special concept which encapsulates such things as preconditions, results, contents, actors or causes.

Problem

Existing Process Model do not capture mathematical/scientific relationship between processes/agents etc. (formula: H2 + 2Cl → 2HCl)

Goals

• declarative process-oriented knowledge representation
• and reasoning tools.
• represent complex science processes in large scale scientific systems (ex. statistical hypothesis, equations).
• Extract knowledge from data (interpret data) using the declarative process descriptions. (Data Mining)
• interpret data that are not yet available, through the reasoning of process models.

We have the technology for doing the expected representational as well as reasoning tasks but we wish to design new set of vocabularies, that can become a standard which would then help in building tools etc. For example PML.

Use Cases

• Information Propagation on the Web (Network Evolution on the Web)
• Earthquake volcano

Meeting

March 16: different from workflow: workflow is more goal oriented, where as our design is more for exploring, more for scientific purpose. different from event: event usual has time component, where our language use for scientific may not need time, as a chemical reaction.

we have set of outcomes, and we are interesting in what processes and inputs may lead to some outcome. HEK Example. current science research limited to deductive study.

use case: same place same time, no time, interesting process involved, reasoning involve.
