Abstract: A video search system includes: an object tag acquisition unit that obtains an object tag associated with an object that appears in a video; a search query acquisition unit that obtains a search query; a similarity calculation unit that calculates a similarity degree between the object tag and the search query; and a video search unit that searches for a video corresponding to the search query on the basis of the similarity degree. According to such a video search system, it is possible to properly recognize the video, for example, by using the search query using a natural language.
