Learning Paths Graph is a directed graph which represents all possible learning paths (sequence of learning resources) that matches the learning goal in hand. | Learning Paths Graph is a directed graph which represents all possible learning paths (sequence of learning resources) that matches the learning goal in hand. | ||
To construct the LPG, for each concept of the [[Concepts_Path_Graph|Concepts Path Graph (CPF)]] related learning resources are selected from the Media Space based on the connection between the Domain Concept Ontology and the Resource Description Model. | To construct the LPG, for each concept of the [[Concepts_Path_Graph|Concepts Path Graph (CPF)]] related learning resources are selected from the Media Space based on the connection between the Domain Concept Ontology and the Resource Description Model. | ||
Each node in the [[Concepts_Path_Graph|CPF]]is then replaced by the related set of learning resources retrieved from the Media Space. | Each node in the [[Concepts_Path_Graph|CPF]] is then replaced by the related set of learning resources retrieved from the Media Space. | ||

Assuming that the Media Space does not contain circular references between learning resources, the LPG is again a simple acyclic | The final graph is the Learning Paths Graph.
