Abstract: The disclosure generally describes methods, software, and systems, including a method for generating suggestions for extensions to data sets. Using metadata for a plurality of documents, data relationships are determined between sets of documents of the plurality of documents. Each set of documents originates from different data sources and does not share common ontologies. The metadata includes terms and labels for documents in the plurality of documents. Using the determined data relationships, enhancement suggestions are determined. Each enhancement suggestion identifies pieces of information from at least one first document in the set of documents that can serve as an extension to information contained in a second document in the set of documents. The identified enhancement suggestions are ranked based on enhancement usability ranking factors. The ranked enhancement suggestions are provided.
