1. A method comprising: obtaining, by a processor, a target knowledge graph generated based on content of a target work, the target knowledge graph including target nodes that represent concepts used within the target work and target edges between target nodes that represent links used within the target work to associate the concepts used within the target work to each other; obtaining, by the processor, a background knowledge graph generated based on content of at least one background work associated with the content of the target work, the background knowledge graph including background nodes that represent concepts used within the at least one background work and background edges between background nodes that represent links used within the at least one background work to associate the concepts used within the at least one background work to each other; comparing, by the processor, at least a portion of the target knowledge graph to at least a portion of the background knowledge graph; and identifying, based on the comparing and by the processor, a potential inconsistency between the at least one background work and the target work.
9. The method of claim 1 , further comprising: determining that a first subgraph of a plurality subgraphs of the background knowledge graph corresponds more closely with the target knowledge graph than remaining subgraphs of the plurality of subgraphs; and selecting, based on the determining, the first subgraph as the at least the portion of the background knowledge graph.
