Info
  • Parent Topics and their child relationships are originated from the Ontology generation process. Additional, branches and sub-branch nodes are added by curators for adding Artifacts.

  • Object Topics are not provided Out-of-Box. These are manually created by Curators or Admins.

  • When an Artifact is curated, candidate object topics are suggested by the curation process.

    • If the Object topic identified for the Artifact already exists in the graph, it is automatically related to the topic.

    • If a new Object topic is identified, the Artifact is related to the selected Domain Node and the QnA is related to the Artifact as a child node. Such an Artifact cannot be published until it is placed under a topic node. This ensures the artifact is assigned to an appropriate topic.

Edit a Node

A topic node in Knowledge Graph is important for the identification of artifacts. It is used to find appropriate Artifacts for a Search query and disambiguate in the case of Guided conversation. It is essential that Topic node details are correct and relevant to ensure the new Artifacts are associated with the correct Topic and appear in suitable searches.

As a curator, you can manage and update Domain and Topic node details in the Knowledge Graph. To do so, follow the below steps:

  • Select the required node in the graph.

  • Click on the Edit Node option.
