Abstract
An application for creating an editing a knowledge graph for document retrieval and exploration. The application may create a data structure, arranged as a directed acyclic graph (DAG), based on user input indicative of categories within a taxonomy and documents within an information repository. The DAG may have a top-level node, interior nodes, and leaf nodes. Interior nodes correspond to taxonomic classifications and point to other interior nodes or leaf nodes. Leaf nodes have corresponding interior nodes and include links to one or more documents in the information repository. The application permits editing of nodes, but does so in a way that preserves links to the arrangement of nodes prior to the editing. The application also permits traversal of nodes of the data structure via a user interface in which a representation of a given node includes an indication of one or more possible paths for reaching the given node.
