US Patent 10452781 Data provenance system

An electronic artifact is accessed which includes content of a particular type of media. Text is determined corresponding to the content and natural language processing is performed on the text to identify at least a subset of words in a statement within the text and determine meanings of each word in the subset of words. A context image is generated for the electronic artifact based on the natural language processing, where the context image includes a graph including nodes corresponding to the subset of words and the context image defines relationships between the subset of words.
