Abstract

The invention discloses a search method and a device based on feature extraction, a computer device and a storage medium. The method comprises the steps of obtaining a search instruction for searchinga plurality of data sources; extracting text data source features, picture data source features, video data source features and voice data source features; converting the keyword characters into keyword pictures, keyword videos and keyword voices; correspondingly calculating a matching degree value of the keyword text and the text data source feature, calculating a matching degree value of the keyword picture and the picture data source feature, calculating a matching degree value of the keyword video and the video data source feature, and calculating a matching degree value of the keyword voice and the voice data source feature; acquiring a hit result set composed of a plurality of specified data sources; and sorting the specified data sources in the hit result set according to a presetsorting method to obtain a search result list, and outputting the search result list. Therefore, the search accuracy is improved.

Description

technical field [0001] The present application relates to the field of computers, in particular to a search method, device, computer equipment and storage medium based on feature extraction. Background technique [0002] Search is an effective means of obtaining information in the network information society. The current search method generally receives the keywords input by the user first, and then judges whether the same keyword exists in the data source. If it is determined that the same keyword exists in the data source, Then, the data source is presented as a hit result. This search method is only suitable for searching text data sources, but not suitable for image data sources, video data sources and voice data sources. However, in the current information network, there are a large number of pictures, videos and voices, so the search scheme of traditional technology will miss these data sources, so the search accuracy cannot be guaranteed.
