18. A system, comprising: a processor; and a memory device accessible to the processor, wherein the memory device includes instructions that, when executed by the processor, cause the processor to: generate a plurality of intent maps representing event structures based on sentences included in a plurality of documents, the plurality of intent maps including a first intent map corresponding to a first document and a second intent map corresponding to a second document, wherein the instructions that cause the processor to generate the plurality of intent maps cause the processor to: parse a selected document to identify one or more sentences included in the selected document; and extract an event structure from at least one sentence of the one or more sentences, wherein the event structure includes data descriptive of an actor and an action described in the at least one sentence; perform a comparison of event structures of the first intent map and event structures of the second intent map; and determine, based on the comparison, whether at least a portion of the first document is duplicative of at least a portion of the second document.

The system claim 18 , further comprising instructions that, when executed by the processor, cause the processor to identify a unique set of event structures corresponding to the plurality of documents by comparing each intent map of the plurality of intent maps to each other intent map of the plurality of intent maps.
