RuleBasedScheduling¶
Generalization is NonDeterministicDeclarative.
Superclass hierarchy
Definition¶
RuleBasedScheduling perform a fact check on Rules from the RuleSet testing their condition part against the facts in the ResearchDataStore. Fact checking may be assisted by a Curator who can semantically compare the condition part of each candidate Rule with the facts. The fact checker returns the next Activity
RuleBasedScheduling performs the following function:
<i>factcheck (RuleSet, ResearchDataStore, Curator): Activity</i>
Examples¶
One real life situation in which rule-based scheduling is performed involves data virtualization. Here the research datastore has a catalog of views available for use. RuleBasedScheduling might explore the catalog to determine the rule(s) in the RuleSet that currently apply. A software Curator might assist in the decision in case there was no exact match between a rule and its condition(s) and the current state of the research datastore. The curator uses Natural Language Processing.
Explanatory notes¶
RuleBasedScheduling is guided by its SchedulingStrategy. This is an enumeration that consists of forwardChaining and backardChaining.
