Description
The Web of Data, a collection of machine-interpretable facts on the Web, has become the largest knowledge base ever built, and is in wide practical use. With thousands of datasets worldwide, containing billions of facts, it is the first knowledge base large enough to display complex system properties. With its scale, context dependency and dynamics it has outgrown its traditional model-theoretic semantics. Is the meaning of a node dependent on the cluster ("context") in which it appears? Is the pathlength between two nodes related to their "semantic distance"? Do densely connected nodes contain more "information"? Properties such as clustering, connectivity and pathlength are not explained by traditional model-theoretic semantics. Do such properties contribute to the meaning of a knowledge graph? Our central research questions are therefore: Q1. What are the principles that govern the structure of very large knowledge graphs? Q2. How is the meaning of a knowledge graph affected by its structure? Q3. Can we design algorithms that exploit the graph structure for effective use of very large knowledge graphs We have promising early results on scale-free properties of large knowledge graphs, on exploiting the graph structure to handle inconsistency, and on methods to compute a graph?s information content. MaestroGraph will give us insights in the organisational principles of large knowledge graphs, leading to better algorithms for querying and inference. It will be a first step towards a new paradigm in knowledge representation, combining the traditional model-theoretic understanding of meaning with theories from large-scale networks and information theory.
