Abstract

The invention discloses a method, a device, equipment, a medium and a product for determining related patents, wherein the method comprises the steps of determining a patent retrieval mode corresponding to a current browsing patent when the current browsing patent is detected, wherein the patent retrieval mode is semantic retrieval or non-semantic retrieval, and determining a target related patent corresponding to the current browsing patent from a retrieval database based on target content in the current browsing patent and retrieval text corresponding to the current browsing patent if the patent retrieval mode is semantic retrieval. The method solves the problem that in the prior art, in the process of carrying out patent retrieval, the retrieval result is inaccurate only based on keyword matching or simple semantic analysis, and realizes quick and accurate determination of the patent which is more in line with the retrieval intention of the user according to the current browsing patent of the user, thereby improving the patent retrieval experience effect of the user.
