The basics of Knowledge Graphs. Knowledge Graphs (KGs) are a way of structuring information in graph form, by representing entities (eg: people, places, objects) as nodes, and relationships between entities (eg: being married to, being located in) as edges. Facts are typically represented as “SPO” triples: (Subject, Predicate, Object). First, graph mining approaches tend to extract too many patterns for a human analyst to interpret (pattern explosion). Second, real-life KGs tend to differ from the graphs usually treated in graph mining: they are multigraphs, their vertex degrees tend to follow a power-law, and the way in which they model knowledge can produce spurious patterns.Reasoning over time in such dynamic knowledge graphs is not yet well understood. To this end, we present Know-Evolve, a novel deep evolutionary knowledge network that learns non-linearly evolving entity representations over time. The occurrence of a fact (edge) is modeled as a multivariate point process whose intensity function is modulated by ...
