In this paper, the authors investigate how a user could be aided to explore linked data in a way leading to expanding their domain knowledge. Earlier work has confirmed that users can gain knowledge while exploring information spaces generated from semantic databases. In such exploration, semantic links can play a key role. However, the learning effect of exploration through linked data has not been investigated and is usually unsupported. This paper is to design a way to nudge the user to paths which can have higher knowledge utility, and at the same time avoid known usability drawbacks.
