Description

Patent retrieval method, device and storage medium Technical Field The application belongs to the field of retrieval, and particularly relates to a patent retrieval method, a patent retrieval device and a storage medium. Background Traditional boolean searches rely on boolean logic of keyword searches to locate documents to be searched. Because of the binary nature of boolean logic, the user cannot employ too many keywords in order to prevent false negatives. And the user wants to rank the most relevant documents to the front by semantic ranking in order to find the appropriate relevant documents. At present, a user can only adopt a small number of keywords to locate corresponding search documents, but semantic ranking can only provide a scalar (number) degree of relevance of 0-100%, and besides informing that the documents all meet the condition of Boolean search, the user cannot further provide more document information. Therefore, the user has a large amount of reading tasks, and a large amount of time is wasted by reading and finding out more patent documents satisfying the keywords (technical elements) focused by the user. Disclosure of Invention The application provides a patent retrieval method, a device and a storage medium, which can find out the most suitable retrieval parameter combination by browsing parameter labels of the retrieval parameter combination, and further retrieve corresponding patent documents, thereby greatly reducing retrieval time. The first aspect of the present application provides a patent retrieval method, including: Providing a retrieval interface; Determining search conditions on the search interface according to a condition determination operation instruction of a user; determining a retrieval parameter corresponding to the retrieval condition, wherein the retrieval parameter comprises at least one of a keyword, IPC and CPC; Determining P search parameter combinations corresponding to the search parameters, wherein P is an integer greater than or equal to 1; And searching a target data set based on the P search parameter combinations to obtain a patent literature set hit by each search parameter combination in the P search parameter combinations, wherein the target data set corresponds to the search condition. A second aspect of the present application provides a patent retrieval device comprising: an interface providing unit for providing a search interface; the first determining unit is used for determining the search conditions on the search interface according to the condition determination operation instruction of the user; A second determining unit, configured to determine a search parameter corresponding to the search condition, where the search parameter includes at least one of a keyword, IPC, and CPC; a combination unit, configured to determine P search parameter combinations corresponding to the search parameters, where P is an integer greater than or equal to 1; And the searching unit is used for searching a target data set based on the P search parameter combinations to obtain a patent document set hit by each search parameter combination in the P search parameter combinations, wherein the target data set corresponds to the search condition. A third aspect of the present application provides a computer device comprising at least one connected processor, a memory and a transceiver, wherein the memory is adapted to store program code, and the processor is adapted to invoke the program code in the memory to perform the steps of the patent retrieval method described in the first aspect above. A fourth aspect of the present application provides a computer storage medium comprising instructions which, when run on a computer, cause the computer to perform the steps of the patent retrieval method described in the first aspect above. Compared with the related art, in the embodiment provided by the application, the patent retrieval device determines the retrieval conditions on the retrieval interface according to the condition determination operation instruction of the user, determines the retrieval parameters corresponding to the retrieval conditions, wherein the retrieval parameters comprise keywords, IPC (Internet protocol) and CPC (physical control center), performs arbitrary combination on the keywords, the IPC and the CPC in the retrieval parameters to obtain P retrieval parameter combinations, and performs retrieval on the target data set based on the P retrieval parameter combinations to obtain the patent literature hit by each retrieval parameter combination in the P retrieval parameter combinations. Therefore, a user can find out the most suitable search parameter combination by browsing the search parameter combination label without reading each searched patent document, and further search the corresponding patent document, so that the search time is greatly reduced.
