In this survey we look at what techniques assist users in exploring large knowledge graphs. Knowledge graph exploration entails the process of finding information in knowledge graphs without knowing what we are looking for.
In this paper:
- We propose a taxonomy for knowledge graph exploration techniques (see Figure above).
- We categorize the available work in three large categories: Summarization & Profiling, Exploratory analytics, and Exploratory Search.
- We present challenges and the road ahead to foster further research and open to industrial applications.
