8. A method comprising:
identifying an erroneous term in a text portion of a video asset;
identifying an object in a video frame from the video asset, wherein a descriptor of the identified object is not a candidate correction term for the erroneous term;
analyzing the identified object in the video frame, using image recognition, to identify an object category based on the descriptor of the identified object;
identifying the candidate correction term for the erroneous term that belongs to the identified object category, wherein the identifying the candidate correction term that belongs to the identified object category comprises:
extracting a keyword from the text portion of the video asset;
searching a knowledge graph for nodes corresponding to the identified object category and the keyword;
analyzing the nodes for properties associated with the identified object category and the keyword; and
determining at least one other node based at least in part on the properties associated with the identified object category and the keyword, wherein the at least one other node corresponds to the candidate correction term that belongs to the identified object category; and
replacing the erroneous term in the text portion of the video asset with the identified candidate correction term.
