Systems and techniques for facilitating link analysis may be implemented by storing data regarding a knowledge domain. The data may include information about nodes and reflective links. Each node may represent an entity in the knowledge domain. Each reflective link may represent a relationship between a respective pair of nodes, including a first node and a second node. Each reflective link may include information about a first set of characteristics for the relationship of the first node to the second node and a second set of characteristics for the relationship of the second node to the first node. By allowing the first set of characteristics to be different from and to include reflective characteristics of the second set of characteristics, different properties and functions can be associated with each direction of the reflective link. Link analysis may be performed on nodes and reflective links to more effectively infer new knowledge.
