Resolving conflicts between data source updates and user edits to ontology data

A computer-implemented method of resolving conflicts in changes to ontology data, comprising:

• receiving a set of data source updates for one or more datasets from one or more data sources;
• receiving one or more sets of user edits to an ontology,
• the ontology including a definition for each ontology entity type of a plurality of ontology entity types,
• the ontology including a plurality of ontology entities instantiated from the plurality of ontology entity types;
• transforming the set of data source updates to a list of updates to the ontology based on a first mapping between the one or more datasets and the plurality of ontology entity types;
• merging the list of updates to the ontology with the one or more sets of user edits into a merged dataset;
• and
• resolving conflicts in the merged dataset related to a first ontology entity type by reviewing data in the merged dataset in a chronological order based on a first strategy that prioritizes a user edit over a data source update, comprising:
• determining that a current user edit to a first ontology entity of the first ontology entity type in the merged dataset is to create the first ontology entity and no earlier user edit to the first ontology entity was to delete the first ontology entity;
• and
• disregarding any later data source update to the first ontology entity in the merged dataset,
• wherein the computer-implemented method is implemented using one or more processors.
