Title
Exploring Semantic Graphs using Summaries

Abstract
The explosion of the web and the abundance of linked data have led to the need for effective and efficient methods for exploration, storage, management, and querying. In this direction, semantic summaries have been proposed as a key technology for the quick exploration and understanding of large knowledge graphs. Structural semantic summarization exploits first and foremost the structure of the graph in order to construct the corresponding summaries. In this talk, we initially show how to construct high-quality structural semantic summaries using a plethora of techniques, considering centrality measures, given workloads, and machine learning. Then we will explain how to use these summaries for data exploration tasks, using zoom operations and incremental procedures. Finally, we will proceed to demonstrate how such summaries can be used on big data distributed platforms for efficient query answering, minimizing data access, and effectively grouping data usually queried together.
