1. A method for reducing churn in identifier assignment for entities in a knowledge graph, comprising:

  • identifying a plurality of aliases for a plurality of entities maintained in the knowledge graph, wherein each alias of the plurality of aliases is associated with one entity of the plurality of entities, and wherein each entity of the plurality of entities is associated with an entity identifier;

    for each alias of the plurality of aliases, associating the alias with the entity identifier for the entity to which the alias is associated; and

    in response to an update to the knowledge graph;

    clustering the plurality of aliases based on the update into a plurality of alias clusters, wherein each alias retains the association with the entity identifier made prior to the update; and

    for each alias cluster of the plurality of alias clusters, associating the alias cluster with one entity of the plurality of entities by assigning an entity identifier of the one entity to the alias cluster, wherein assigning the entity identifier of the one entity to the alias cluster comprises;

    identifying each unique entity identifier associated with aliases of the alias cluster;

    for each unique entity identifier, determining a number of the aliases associated with the entity identifier;

    identifying, as a most frequent entity identifier, one entity identifier among each unique entity identifier that has a highest determined number of the aliases associated; and

    assigning the most frequent entity identifier to the alias cluster and to the aliases of the alias cluster.
