Detailed Description

Model that updates the trust in peices of knowledge.

Constructor & Destructor Documentation

KnowledgeTrust()

KnowledgeTrust::KnowledgeTrust	(	const dynet::ParameterMap &	parameters,
		Construct *	construct
	)

Loads the networks and parses parameters.

If the trust and/or kttm networks were already loaded, for every element in the knowledge network that is false, the associated elements in the knowledge trust network are set to 0.5 and in the knowledge trust transactive memory network are removed.

Additionally, this model checks that the "agent" nodeset has attributes "can send knowledge trust" and "can receiver knowledge trust".
