Embodiment 1

[0063] figure 1 It is a schematic flowchart of a patent retrieval method based on a patent database in an embodiment of the present invention. Such as figure 1 As shown, the embodiment of the present invention provides a patent retrieval method based on a patent database, the method comprising:

[0064] Step 110: Obtain the first patent.

[0065] Step 120: Determine the first keyword according to the first patent.

[0066] Step 130: Obtain the first search term of the first patent according to the first patent search database.

[0067] Specifically, a first patent is obtained through the patent database, and a semantic analysis is performed on the first patent to obtain the first keyword of the first patent, wherein the first keyword contains the technical elements of the first patent. Obtain the first search term of the first patent according to the existing first patent search database, for example, the examiner's first search term for the first patent can be obtained th...

Embodiment 2

[0085] Based on the same inventive concept as a patent retrieval method based on a patent database in the foregoing embodiments, the present invention also provides a patent retrieval method device based on a patent database, such as figure 2 As shown, the device includes:

[0086] The first obtaining unit 11, the first obtaining unit 11 is used to obtain the first patent;

[0087] A first determining unit 12, the first determining unit 12 is configured to determine a first keyword according to the first patent;

[0088] A second obtaining unit 13, the second obtaining unit 13 is used to obtain the first search term of the first patent according to the first patent search database;

[0089] A third obtaining unit 14, the third obtaining unit 14 is configured to obtain a first impact factor of the first keyword;

[0090] A fourth obtaining unit 15, the fourth obtaining unit 15 is used to obtain the second impact factor of the first search term;

[0091] A second determinati...

Embodiment 3

[0120] Based on the same inventive concept as a patent retrieval method based on a patent database in the foregoing embodiments, the present invention also provides a patent retrieval device based on a patent database, such as image 3 As shown, it includes a memory 304, a processor 302, and a computer program stored in the memory 304 and operable on the processor 302. When the processor 302 executes the program, it realizes the above-mentioned patent retrieval method based on the patent database steps in either method.

[0121] Among them, in image 3 In, bus architecture (represented by bus 300), bus 300 may include any number of interconnected buses and bridges, bus 300 will include one or more processors represented by processor 302 and various types of memory represented by memory 304 circuits linked together. The bus 300 may also link together various other circuits, such as peripherals, voltage regulators, and power management circuits, etc., which are well known in t...

Abstract

The invention provides a patent retrieval method and device based on a patent database, and relates to the technical field of data processing. The method comprises steps of obtaining first patent, determining a first keyword according to the first patent; obtaining a first retrieval word of the first patent according to a first patent retrieval database; obtaining a first influence factor of the first keyword; obtaining a second influence factor of the first search word; determining a joint influence factor according to the first influence factor and the second influence factor; judging whether the joint influence factor is greater than a first preset threshold value or not; when the joint influence factor is greater than a first preset threshold, obtaining a final keyword according to thefirst search word and the first keyword; obtaining the first target patent according to the final keyword, thereby achieving the technical effects of fusing the historical data of the patent retrieval database, improving the retrieval precision and comprehensiveness, and achieving the efficient and quick searching of the target patent.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a patent retrieval method and device based on a patent database. Background technique [0002] Enterprises enhance their competitiveness in the international and domestic markets by building intellectual property barriers, and the government guides industrial development and innovation through intellectual property management. Intellectual property rights have become an important factor of production and the core competitiveness of an enterprise or even an economy. Patents contain a large amount of technical, legal and economic information. Through patent analysis, enterprises can learn the current technological development trends in the industry, which will help enterprises in their later development. And form its own technical protection to avoid infringement and being infringed. With the continuous development and improvement of the social system and the rapid increa...
