When to Trigger Active Rules?

Raman Adaikkalavan, Sharma Chakravarthy
2009 International Conference on Management of Data  
Currently active rules are triggered only when events occur completely.  ...  These rules are termed active rules as they make the underlying application or system such as database management system active capable (i.e., react to changes actively using the push paradigm).  ...  This is a critical issue since active rules associated with an event is triggered iff that event is detected. In other words, an event decides when to trigger the associated active rules.  ...

A concurrent rule scheduling algorithm for active rules

Ying Jin, Susan D. Urban, Suzanne W. Dietrich
2007 Data & Knowledge Engineering  
In particular, since a single event can trigger multiple rules that execute over distributed sources of data, it is important to make use of concurrent rule execution whenever possible.  ...  The use of rules in a distributed environment creates new challenges for the development of active rule execution models.  ...  When an event triggers a rule, the triggered rule can trigger other rules, thus forming a cascaded set of rules triggered by this event.  ...

Data Mining Methods for Rule Designing and Rule Triggering in Active Database Systems

Nasrin Kalanat, Mohammad Reza Kangavari
2015 International Journal of Database Theory and Application  
Additionally an ensemble method is proposed to trigger more appropriate ECA rules when the interesting events occurred.  ...  Active database system has been introduced to extend the database functionality.  ...  When interesting events occurred, each model of the ensemble nominates the ECA rule/s to be triggered.  ...

Digitocracy: Ruling and Being Ruled

Alfonso Ballesteros
2020 Philosophies  
Digital man has animal features and is ruled by his brain's reward system. We need to abandon this new form of government and the resulting man.  ...  If those who are ruled acted like machines, data would not be produced on a mass scale, and machine learning would stop learning.  ...  Humans, in so far as we are animals, when triggered by fear or hunger, act (and ask for help) due to this brain's reward system.  ...

Rule contexts in active databases [chapter]

Martin Sköld, Esa Falkenroth, Tore Risch
1995 Lecture Notes in Computer Science  
However, rules can be directly activated by activating them into a previously activated context. When rule contexts are deactivated all the rules in that context are disabled from triggering.  ...  The same rule can be activated with different parameters and into several different contexts. Rules in a context are not enabled for triggering until the context is activated.  ...  These kinds of rules are usually always active and are triggered when a method is invoked of an instance of the class.  ...

JSON Rules

Adrian Giurca, Emilian Pascalau
2008 Deutsche Jahrestagung für Künstliche Intelligenz  
While the rule engine is enough general, its main purpose is to execute production rules and Event-Condition-Action rules related to the web page DOM processing.  ...  This paper presents a JSON based rule language and its JavaScript-based rule engine towards providing Web 2.0 applications with rule-based inference capabilities.  ...  Opposed to usual rule engines, that stop their activity when no rules can be fired, this stops only when the WorkingMemory exists no more.  ...

Neurosymbolic Alerting Rules

Rosemarie Velik, Harold Boley
2010 IEEE transactions on industrial electronics (1982. Print)  
Integrated with perception, decision-making is based on the rule model of RuleML, which computes alerts to relevant building occupants about current opportunities and risks.  ...  A general model of neuro-symbolic alerting rules is developed and exemplified with a use case of building alerts.  ...  When such derivation rules have decided that a particular user is to be alerted, a top-level reaction rule is triggered to send him/her the actual alerting message.  ...
