Graphs make implicit relationships explicit and graph data science infers new relationships, derives semantics, and enriches the overall context transforming the graphs with natural relationships to truly knowledge graphs. In this session, let’s talk about the journey from graphs to knowledge graphs and leveraging unsupervised graph algorithms and graph analytics to analyze the complex features in your data and deliver deeper insights.

WHAT? Use context and
relationships between data points
to enhance analytics and ML
WHY? Faster, simpler, more
accurate predictions and models
whenever/wherever context
matters.

classification:
“What kind of node
is this?”
Link prediction:
“Should there be a
relationship between
these nodes?”
Labeled data: Pairs of nodes
that are either linked or not
Features: Pre-existing
attributes, algorithms
(pageRank), embedding
