1. A method for disambiguating an ambiguous entity in a search query based on a gaze of a user, the method comprising: monitoring, using control circuitry, at a current time, a gaze of a user during playback of a media asset, wherein monitoring the gaze of the user comprises monitoring a vertical degree of an eye of the user, a horizontal degree of the eye of the user, and a position of the eye of the user relative to a display screen displaying the media asset; determining a size of the display screen displaying the media asset; calculating, based on the position, the size, the vertical degree, and the horizontal degree, a first area of the display screen corresponding to the gaze of the user; storing, in memory, a data structure indicating the first area and the current time; receiving, using the control circuitry, a search query from the user at the current time; determining that the search query includes an ambiguous entity; and based on determining that the search query includes the ambiguous entity: retrieving, from the memory, the data structure; determining a frame of the media asset that correspond to the current time; retrieving, from a database, metadata relating to the frame of the media asset corresponding to the current time, the metadata including a first location of a first entity in the frame, a second location of a second entity in the frame, and a third location of a third entity in the frame; extracting, from the data structure, the first area corresponding to the current time; extracting from the metadata, the first location of the first entity in the frame and the second location of the second entity in the frame; determining that the first area overlaps with the first location of the first entity and the second location of the second entity; based on determining that the first area overlaps with the first location of the first entity and the second location of the second entity: receiving, using the control circuitry, data indicative of a second area from a user device of a second user, wherein the second area was calculated based on a gaze of the second user at the current time; and determining that the second area overlaps with the location of the first entity; based on determining that the second area overlaps with the location of the first entity, generating for display a first prompt for additional input, wherein the first prompt for additional input indicates the first entity as a first potential disambiguation of the ambiguous entity in the search query; subsequent to generating for display the first prompt for additional input, receiving a negative input from the user, wherein the negative input indicates that the first entity is an incorrect disambiguation of the ambiguous entity in the search query; based on receiving the negative input: expanding the first area to a third area of the display screen, wherein the third area is larger than the first area; extracting, from the metadata, the third location of the third entity in the frame; determining that the third area overlaps with the third location of the third entity; and based on determining that the third area overlaps with the third location, generating for display a second prompt for additional input, wherein the second prompt for additional input indicates the third entity as a second potential disambiguation of the ambiguous entity in the search query.
