Cognition disorientation problem is one of the major problems caused by the self-learning principle in the current web based intelligent learning systems. Providing learners with the personalized learning path can effectively smooth over the problem. In this paper, we provide learners with learning paths which is based on the 3 dimensioned SLN (3d_SLN) map according to their different learning styles. 3d_SLN map is a modified version of SLN whose inferring ability is as strong as ontology for learning path recommendation while more flexible in knowledge relation constructing.
