Visual Analysis and Querying of Large Knowledge Graphs
Talk Title
Visual Analysis and Querying of Large Knowledge Graphs
Session Overview
Grasping and querying large Knowledge Graphs (KGs) is challenging. I will demonstrate tooling for RDF as well as LPG graph data that uses visual aggregation to enable exploration and querying of large KGs, from the meta level down to node and relationship details without the hairball problem of graph visualization.
Using production data from an industry project, I will share experiences with our codeless query approach that can guide users in developing meaningful queries without any prior idea of the data or any SPARQL or Cypher language skills to:
- investigate not only the structure but also the proportions of millions of nodes in the KG,
- find data flaws, identify data outliers or missing connections,
- build complex queries including sophisticated filtering and path expressions just by visual exploration,
- refine the graph schema with new classes/labels on the fly while browsing the graph.
Target Audience
Data stewards, data analysts, data owners, data domain experts or any other user with a need for
- graph understanding
- graph data quality analysis
- query building
Desired Feedback
User feedback about the tool set or exchange about alternative approaches / workflows etc.
