SIMILARITY DETERMINING METHOD AND DEVICE, NETWORK TRAINING METHOD AND DEVICE, SEARCH METHOD AND DEVICE, AND ELECTRONIC DEVICE AND STORAGE MEDIUM

摘要

A similarity determining method and device, a network training method and device, a search method and device, and an electronic device and a storage medium. The data similarity determining method comprises: obtaining first data of a first object (S110), wherein the first data comprises first sub-data in a first mode or a second mode; mapping the first sub-data into a first semantic representation in a semantic comparison space (S120), wherein the semantic comparison space enables the semantic representation obtained by mapping the data in the first mode into the semantic comparison space and the semantic representation obtained by mapping the data in the second mode into the semantic comparison space to be computable in similarity; obtaining second data of a second object (S130), wherein the second data comprises second sub-data in the first mode or the second mode; mapping the second sub-data into a second semantic representation in the semantic comparison space (S140); and calculating the similarity between the first data and the second data based at least on the first semantic representation and the second semantic representation (S150).
