Abstract : As more and more knowledge graphs (KG) are published in the Web, there is a need of tools for abstracting their content for their producers to verify their result, and for their consumers to use it. This implies showing the schema-level patterns instantiated in the graph, with the frequency with which they are instantiated. A profile represents this information. In this paper, we propose a new type of profile that we call TT profile, for Types and Terms profile. It shows the used Types and predicates, and also the used Terms because of their paramount importance in most of KGs, especially in the Cultural Heritage (CH) domain. We present an algorithm for building a TT profile from an online KG's assertional part, and we report on experiments performed over a set of CH KGs.
