The invention discloses a method and device for joint retrieval of multi-subject intellectual property data, wherein the method comprises: acquiring an intellectual property field to be retrieved; extracting keywords of a plurality of subject types from the intellectual property field; The keywords of the subject type are searched in the pre-established multi-type subject database to obtain the search results of the intellectual property subject range corresponding to each subject type keyword; the multi-type subject database includes intellectual property data of multiple subject areas, and each subject The intellectual property data of the scope includes multiple levels of intellectual property data, and each level of intellectual property data includes multiple types of intellectual property sub-data; the retrieval results of the intellectual property subject scope corresponding to all subject type keywords are fused to obtain Joint search results of multi-topic IP data. The invention can efficiently and accurately carry out joint retrieval of multi-subject intellectual property data.

Description

technical field [0001] The invention relates to the technical field of big data, in particular to a method and device for joint retrieval of multi-subject intellectual property data. Background technique [0002] This section is intended to provide a background or context to the embodiments of the invention recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] In the prior art, patent search, trademark search, etc. are all carried out based on their own separate databases. If users want to know intellectual property information involving various aspects, they need to query in different databases, and then use third-party tools. The results are integrated, and the retrieval efficiency is low and inaccurate.
