Abstract: In order to implement the foregoing object, an exemplary embodiment of the present disclosure discloses a video retrieval method performed by a computing device. The video retrieval method may include: segmenting one or more video data into two or more unit video data; encoding, by one or more encoders comprised in a machine learning enabled key frame detection module, two or more unit video data; generating one or more key frame detection vectors for each of the two or more unit video data based on the result of the encoding; and generating feature vector of one or more retrieval video data based on a combination of one or more vectors among the key frame detection vectors.

Abstract: In order to implement the foregoing object, an exemplary embodiment of the present disclosure discloses a video retrieval method performed by a computing device. The video retrieval method may include: receiving retrieval query data for one or more video data; generating a retrieval query vector based on the received retrieval query data; comparing the retrieval query vector with a plurality of video retrieval vectors each representing target retrieval video data segmented based on key frame information; and selecting one or more target retrieval video data by the result of the comparison between the retrieval query vector and the plurality of video retrieval vectors.

Abstract: Provided is a method of providing a user interface for video retrieval performed by a computing device, the method including: receiving a search query, providing a search result interface displaying at least one search video content and search section searched by the search query, wherein the search video content and the search section are related with at least one of a plurality of video semantic search attributes corresponding to the search query, and providing a timeline view interface for the search video content when it is determined to display the search result interface according to a timeline view mode, wherein the timeline view interface has a visual characteristic indicating the degree of relevance to at least one of the plurality of video semantic search attributes corresponding to the search query.
