1. An assertion assessment system comprising an assertion database configured to store assertion objects in a multi-layered hierarchical structure, each assertion object has at least one directional link with another assertion object, assertion objects that are linked together in a same direction forms a chain of information sources; and an assessment tracking engine coupled with the assertion database, wherein the assessment tracking engine comprises at least one processor and memory storing software instructions that when executed by the at least one processor causes the at least one processor to perform the following steps: detecting that a user has traversed a first chain of information sources within the multi-layered hierarchical structure, the first chain of information sources comprising at least a first assertion object that is downlink of a second assertion object, and uplink of a third assertion object; monitoring non-assessment interaction data representing the user's non-assessment interaction with the second assertion object; upon receiving the non-assessment interaction data, enabling the user to provide assessment of the first assertion object; receiving, from the user, assessment interaction data representing an assessment of the first assertion object within a first chain of information sources in the multi-layered hierarchical structure; deriving an assertion quality measure as a function of the non-assessment interaction data related to the second assertion object and the assessment interaction data related to the first assertion object; binding the assertion quality measure to the third assertion object; and configuring an output device to present the assertion quality measure associated with the third assertion object.
